The Reno Air Races, officially known as the National Championship Air Races, is a multi-day event tailored to the aviation community that takes place each September at the Reno Stead Airport a few miles north of Reno, Nevada. Air racing is billed as "the world's fastest motor sport" and Reno is one of the few remaining venues. The event includes races in 6 classes and demonstrations by airshow pilots.

The probably most spectacular race class is the "Unlimited". With the exception of very few “scratch-built” aircraft, the Unlimited Class has generally been populated by stock or modified WWII fighters with the P-51 Mustangs, F-8F Bearcats and Hawker Sea Fury being flown most often, flying in speeds exceeding 500 mph.

One of the many P-51 custom racers was the "Gulf Mirage". It was a former military aircraft (ex s/n 44-73350), formerly operated by the Swiss Air Force and bought for around $3,500, that had undergone several successive modifications during its career in order to reduce the aircraft's drag and make it more and more competitive.
"Gulf Mirage" started its racing career in 1968 as an almost original P-51D which had been stripped off of any military equipment, under the ownership of Daniel Haskin, owner of Aeropart Service Inc. and WWII and Korea War pilot veteran. The aircraft's original name was "Mirage", with the civil registration N613C. The debut with the racing number 83 saw only a mediocre result, and, for the next season, the yellow and purple Mustang underwent its first major modifications.
These were carried out by Aero Trans Corp. DBA in Ocala, Florida, and included clipped wings and ailerons (the wing span was reduced by a total of ~5'), and the Mustang's characteristic tunnel radiator was replaced by two recessed radiators, which now occupied the former machine gun compartments in the wings. In this guide, the aircraft took part in the 1969 National Air Races, but severe cooling problems and numerous leaks in the almost untested radiator system prevented an active participation in the Unlimited Class races.
1970, "Mirage" was back, now tested and most technical bugs sorted out, and was able to achieve a respectable 4th place. In 1971, the modified Mustang was back, but during the main race a piston jammed and the aircraft could hardly be controlled - ending in a rugged belly landing after the landing gear had collapsed upon touchdown, which also caused a crack in the motor block.

However, the airframe was mostly intact, and Daniel Haskin started to search for sponsors for a rebuild and upgrade of "Mirage", as well as a new pilot. Through his industrial connections, he was able to win Grady Davis, vice president of Gulf Oil, who was an avid motorsport enthusiast and had founded the Gulf Oil Racing Team in 1966, for his project. In the course of 1972, "Mirage" underwent, thanks to financial and technical support, its second radical modification: the ruined Merlin engine was replaced by a bigger Rolls Royce Griffon (salvaged from an ex RAF Supermarine Spitfire PR Mk 19 reconnaissance aircraft) and its respective engine mounts, now driving a five blade propeller. The wing radiators were slightly enlarged in order to match the Griffon's increased power, and the aircraft was rebuilt with an eye to weight reduction. In the end, 600 pounds (270 kg) were removed from the airframe. The Mustang's original bubble canopy was replaced by a much smaller, streamlined fairing, and, after initial flight tests, the fin was slightly extended in order to counter the new propeller's torque and improve directional stability.
Outwardly, the new sponsorship resulted in a new name - the aircraft was now called "Gulf-Mirage" - a new, very different livery in the typical Gulf Racing colors: light blue with bright orange trim. With Peter Holm, a new pilot was found, too.

1973 saw the first start of the refurbished aircraft with the new starting number 63, but "Gulf-Mirage" did not finish its first race due to oil pressure problems, and any further flights were cancelled. In 1974 the pale blue Mustang was back - and this time everything worked fine and "Gulf-Mirage" was able to score a 3rd place in the Unlimited Class Gold Race. In 1975 the aircraft raced at the California National Air Races and finished in 2nd place - with a speed of 422 miles per hour (679 km/h).

After racing for several years with limited success, the aircraft was sold in 1983 to Wiley Sanders of Sanders Truck Lines, and it lost its characteristic blue and orange livery. After frequent participations in various air races, the aircraft was sold again in late 1989 and moved to the United Kingdom, not to return to the United States again until 1995. Since then, the aircraft has not made any public appearance yet.

The kit and its assembly:

This is another group build submission, this time the topic was “Racing and Competition” – and what’s more obvious than a (fictional) Reno Racer? The Mustang is a classic choice for the Unlimited Class, with many warbirds and some exotic, dedicated constructions with high-volume piston engines. I wanted something plausible, though, that perfectly blends into the class’ pedigree, so I took inspiration from different real P-51 racers and modified my build with whatever I considered plausible.

The basic kit is Academy’s P-51D, which I like because of its good fit, surface structure and nice details like the good cockpit and landing gear, as well as the option to build the model with lowered flaps. Just the tail wheel is IMHO a little short and needs an extension at its base for a proper stance of the model.

However, in order to turn the Mustang into a mutated Reno Racer and high speed aircraft, I gave it the following modifications – everything gathered from real-world Mustang modifications throughout the years:

Clipped wings, a traditional way to reduce drag and improve low altitude handling. I cut away about 1cm from each wing – and there have been more radical modifications in real life, even including the transplantation of swept wings from a Learjet! The original wing tips were retained, though, and slightly extended so that they would match with the slightly deeper, shortened wing.

The ventral radiator was cut away and faired over; instead, two smaller radiators were integrated into the wings where the machine gun bays had been, scratched from styrene sheet material. This was inspired by Anson Johnson’s Mustang N13Y, as flown in 1949.

The spacious bubble canopy was replaced by a much smaller hood. At first, I wanted to use a Spitfire or Typhoon bubble canopy, but, after some dry fitting tests, these were still too big for a radical racer. Eventually I came up with a weird combo: the cockpit glazing from an 1:100 Tamiya Il-28 bomber (which, unfortunately, turned out to be quite thick), extended rearwards with the rear section of an 1:72 Academy Fw 190 cockpit canopy/fairing. Both had to be tailored to match each other, as well as the Mustang’s different fuselage shape, and the cockpit opening itself in the fuselage had to be drastically made smaller, with the help of styrene sheet and lots of PSR.

The engine was upgraded from a V-1710/Merlin to a Griffon engine; this was pretty easy, thanks to the transplantation of conformal rocker cam fairings from a Special Hobby Spitfire kit: they almost match the cowling shape perfectly!

In order to create a more Griffon-esque look (using the Griffon-powered RB-51 “Red Baron” Mustang as benchmark), I made the original carburetor air intake under the propeller disappear and modified the lower cowling. A new carburetor intake was scratched from a piece of a small drop tank and placed further back, just in front of the landing gear wells. Looks very Spitfire-like now!

Additionally, a different propeller with more blade area was incorporated, a one-piece five-blade propeller from a Frog Spitfire Mk. XIV. The new piece was mounted onto a metal axis and a styrene tube adapter was inserted into the Mustang’s nose. Since the new propeller’s spinner came with a slight increase in diameter (overall maybe just 1mm, but it would be recognizable), the cowling was adjusted accordingly, realized through some PSR work.

As a visual counterbalance to the bigger nose section, the fin tip was slightly extended (maybe by 2mm) through the integration of a piece from a Special Hobby He 100.

Finally, the OOB pitot under the wing was replaced by a more delicate alternative made from thin wire, and no other antennae were fitted, for a sleek and clean look.

In the end, a lot of changes - but the overall effect is IMHO still subtle, and the whole thing looks quite plausible. And there had been more radical conversions in real life!

Painting and markings:

This started as a tough challenge, since I wanted a simple livery, yet something well-known from the Seventies. One option was a black “JPS Special” livery, but I eventually came across a very nice “Gulf Racing” sponsor markings set from A.C.B.-Shop, a German car model specialist. The team’s light blue and orange cars are still iconic and popular today, and why should Gulf Oil not even have sponsored a Reno Racer…?

Painting started with an overall coat of pastel blue from the rattle can – a generic tone from Duplicolor, which comes close to RAL 5024, but it’s less saturated. Initially I thought that the blue tone was just too pale, but things became more convincing once I added orange bands (Humbrol 18, it comes very close to the decals’ tone) to the wings and the fuselage, as well as to the nose section and the spinner. The latter received a chrome silver tip, created with Humbrol’s Polished Aluminum metallizer, which was also used on the blades’ front side. Their back side became black. Black was also used for a narrow anti-glare panel in front of the windscreen.

The cockpit interior became dark grey while the landing gear wells and covers were painted in zinc chromate yellow (Humbrol 81) – an ugly but deliberate contrast to the colorful exterior. The struts were painted in aluminum (Humbrol 56). As another color highlight, the wheel discs were painted in bright red – seen on a WWII Mustang, probably a personal addition of the pilot?

Once dry, the kit received a light black ink wash, in order to emphasize the engraved panel lines. Then orange sections received black rims, created with generic 2mm decal stripe material from TL Modellbau. The lowered flaps were a bit problematic, but the curved trim under the nose posed serious problems because the straight decal stripes had to be bent into curves. Thanks to some Gunze decal softener, this eventually worked – not perfect, but O.K. for what I wanted to achieve.

Next came the major sponsor markings and the race numbers. The Gulf logos came from the aforementioned decal set while the number was puzzled together with white decal circles from a Hasegawa Ki-61 (actually foundations for hinomaru with white borders!) and single numerals, which actually belong to contemporary Russian Air Force aircraft, from a Begemot sheet with generic tactical codes in various sizes.

In the scrap box I also found some sponsor decals (from a Heller 1:43 Lancia Delta), and some stencils were taken from an Academy P-47D sheet.

Finally, after some finishing touches, the kit was sealed with semi-gloss acrylic varnish from Italeri.

Well, the “Gulf-Mirage” looks simple and plausible, but in the end a lot of modifications were integrated that shift the Reno Racer away from the standard warbird. I am actually quite pleased with the outcome, because neither the technical modifications, nor the fictional/adapted Gulf Racing livery look out of place. The combo works well!

+++ DISCLAIMER +++

Nothing you see here is real, even though the model, the conversion or the presented background story might be based historical facts. BEWARE!

Some background:

The Georgian Air Force and Air Defense Division (თავდაცვის ძალების ავიაციისა და საჰაერო თავდაცვის სარდლობა; tavdatsvis dzalebis aviatsiisa da sahaero tavdatsvis sardloba) was established on January 1, 1992, and in September the Georgian Air Force conducted its first combat flight during the separatist war in Abkhazia. On August 18, 1998, the two divisions were unified in a joint command structure and renamed the Georgian Air Force.

In 2010, the Georgian Air Force was abolished as a separate branch and incorporated into the Georgian Land Forces as Air and Air Defense sections. By that time, the equipment – primarily consisting of Eastern Bloc aircraft inherited from the Soviet Union after the country’s dissolution – was totally outdated, the most potent aircraft were a dozen Suchoj Su-25 attack aircraft and a handful of MiG-21U trainers.

In order to rejuvenate the air arm, Tbilisi Aircraft Manufacturing (TAM), also known as JSC Tbilaviamsheni and formerly known as 31st aviation factory, started a modernization program for the Su-25, for the domestic forces but also for export customers. TAM had a long tradition of aircraft production within the Soviet Union. In the 1950s the factory started the production of Mikoyan's MiG-15 and later, the MiG-17 fighter aircraft. In 1957 Tbilisi Aircraft State Association built the MiG-21 two-seater fighter-trainer aircraft and its various derivative aircraft, continuing the MiG-21 production for about 25 years. At the same time the company was manufacturing the K-10 air-to-surface guided missile. Furthermore, the first Sukhoi Su-25 (known in the West as the "Frogfoot") close support aircraft took its maiden voyage from the runway of 31st aviation factory. Since then, more than 800 SU-25s had been delivered to customers worldwide. From the first SU-25 to the 1990s, JSC Tbilaviamsheni was the only manufacturer of this aircraft, and even after the fall of the Soviet Union the production lines were still intact and spares for more than fifty complete aircraft available. Along with the SU-25 aircraft 31st aviation factory also launched large-scale production of air-to-air R-60 and R-73 IR guided missiles, a production effort that built over 6,000 missiles a year and that lasted until the early 1990s. From 1996 to 1998 the factory also produced Su-25U two-seaters.

In 2001 the factory started, in partnership with Elbit Systems of Israel, upgrading basic Su-25 airframes to the Su-25KM “Scorpion” variant. This was just a technical update, however, intended for former Su-25 export customers who would upgrade their less potent Su-25K export aircraft with modern avionics. The prototype aircraft made its maiden flight on 18 April 2001 at Tbilisi in full Georgian Air Force markings. The aircraft used a standard Su-25 airframe, enhanced with advanced avionics including a glass cockpit, digital map generator, helmet-mounted display, computerized weapons system, complete mission pre-plan capability, and fully redundant backup modes. Performance enhancements included a highly accurate navigation system, pinpoint weapon delivery systems, all-weather and day/night performance, NATO compatibility, state-of-the art safety and survivability features, and advanced onboard debriefing capabilities complying with international requirements. The Su-25KM had the ability to use NATO-standard Mark 82 and Mark 83 laser-guided bombs and new air-to-air missiles, the short-range Vympel R-73. This upgrade extended service life of the Su-25 airframes for another decade.
There were, however, not many customers. Manufacturing was eventually stopped at the end of 2010, after Georgian air forces have been permanently dismissed and abolished. By that time, approximately 12 Scorpions had been produced, but the Georgian Air Force still used the basic models of Su-25 because of high cost of Su-25KM and because it was destined mainly for export. According to unofficial sources several Scorpions had been transferred to Turkmenistan as part of a trade deal.

In the meantime, another, more ambitious project took shape at Tbilisi Aircraft Manufacturing, too: With the help of Israel Aircraft Industries (IAI) the company started the development of a completely new attack aircraft, the TAM-1 “Gvelgeslas” (გველგესლას, Viper). It heavily relied on the year-long experience gathered with Su-25 production at Tblisi and on the tools at hand, but it was eventually a completely new aircraft – looking like a crossbreed between the Su-25 and the American A-10 with a T-tail.

This new layout had become necessary because the aircraft was to be powered by more modern, less noisy and more fuel-efficient Rolls Royce AE 3012 turbofan engines - which were originally intended to power the stillborn Yakovlev Yak-77 twin-engine business jet for up to 32 passengers, a slightly derated variant of the GMA 3012 with a 44 in diameter (112 cm) fan and procured via IAI from the United States through the company’s connection with Gulfstream Aerospace. Their larger diameter (the Su-25’s original Soyuz/Tumansky R-195 turbojets had a diameter of 109,5 cm/43.1 in) precluded the use of the former integral engine nacelles along the fuselage. To keep good ground clearance against FOD and to protect them from small arms fire, the engine layout was completely re-arranged. The fuselage was streamlined, and its internal structure was totally changed. The wings moved into a low position. The wings’ planform was almost identical to the Su-25’s, together with the characteristic tip-mounted “crocodile” air brakes. Just the leading edge inside of the “dogteeth” and the wing roots were re-designed, the latter because of the missing former engine nacelles. This resulted in a slightly increased net area, the original wingspan was retained. The bigger turbofans were then mounted in separate pods on short pylons along the rear fuselage, partly protected from below by the wings. Due to the jet efflux and the engines’ proximity to the stabilizers, these were re-located to the top of a deeper, reinforced fin for a T-tail arrangement.

Since the Su-25’s engine bays were now gone, the main landing gear had to be completely re-designed. Retracting them into the fuselage or into the relatively thin wings was not possible, TAM engineers settled upon a design that was very similar to the A-10: the aircraft received streamlined fairings, attached to the wings’ main spar, and positioned under the wings’ leading edges. The main legs were only semi-retractable; in flight, the wheels partly protruded from the fairings, but that hardly mattered from an aerodynamic point of view at the TAM-1’s subsonic operational speed. As a bonus they could still be used while retracted during emergency landings, improving the aircraft’s crash survivability.

Most flight and weapon avionics were procured from or via Elbit, including the Su-25KT’s modernized “glass cockpit”, and the TAM-1’s NATO compatibility was enhanced to appeal to a wider international export market. Beyond a total of eleven hardpoints under the wings and the fuselage for an external ordnance of up to 4.500 kg (9.900 lb), the TAM-1 was furthermore armed with an internal gun. Due to procurement issues, however, the Su-25’s original twin-barrel GSh-30-2 was replaced with an Oerlikon KDA 35mm cannon – a modern variant of the same cannon used in the German Gepard anti-aircraft tank, adapted to the use in an aircraft with a light-weight gun carriage. The KDA gun fired with a muzzle velocity of 1,440 m/s (4,700 ft/s) and a range of 5.500m, its rate of fire was typically 550 RPM. For the TAM-1, a unique feature from the SPAAG installation was adopted: the gun had two magazines, one with space for 200 rounds and another, smaller one for 50. The magazines could be filled with different types of ammunition, and the pilot was able select between them with a simple switch, adapting to the combat situation. Typical ammunition types were armor-piercing FAPDS rounds against hardened ground targets like tanks, and high explosive shells against soft ground targets and aircraft or helicopters, in a 3:1 ratio. Other ammunition types were available, too, and only 200 rounds were typically carried for balance reasons.

The TAM-1’s avionics included a SAGEM ULISS 81 INS, a Thomson-CSF VE-110 HUD, a TMV630 laser rangefinder in a modified nose and a TRT AHV 9 radio altimeter, with all avionics linked through a digital MIL-STD-1553B data bus and a modern “glass cockpit”. A HUD was standard, but an Elbit Systems DASH III HMD could be used by the pilot, too. The DASH GEN III was a wholly embedded design, closely integrated with the aircraft's weapon system, where the complete optical and position sensing coil package was built within the helmet (either the USAF standard HGU-55/P or the Israeli standard HGU-22/P), using a spherical visor to provide a collimated image to the pilot. A quick-disconnect wire powered the display and carried video drive signals to the helmet's Cathode Ray Tube (CRT).

The TAM-1’s development was long and protracted, though, primarily due to lack of resources and the fact that the Georgian air force was in an almost comatose state for several years, so that the potential prime customer for the TAM-1 was not officially available. However, the first TAM-1 prototype eventually made its maiden flight in September 2017. This was just in time, because the Georgian Air Force had formally been re-established in 2016, with plans for a major modernization and procurement program. Under the leadership of Georgian Minister of Defense Irakli Garibashvili the Air Force was re-prioritized and aircraft owned by the Georgian Air Force were being modernized and re-serviced after they were left abandoned for 4 years. This program lasted until 2020. In order to become more independent from foreign sources and support its domestic aircraft industry, the Georgian Air Force eventually ordered eight TAM-1s as Su-25K replacements, which would operate alongside a handful of modernized Su-25KMs from national stock. In the meantime, the new type also attained interest from abroad, e. g. from Bulgaria, the Congo and Cyprus. The IDF thoroughly tested two early production TAM-1s of the Georgian Air Force in 2018, too.

The kit and its assembly:

This rather rigorous conversion had been on my project list for many years, and with the “Gunships” group build at whatifmodellers.com in late 2021 I eventually gathered my mojo to tackle it. The ingredients had already been procured long ago, but there are ideas that make you think twice before you take action…

This build was somewhat inspired by a CG rendition of a modified Su-25 that I came across while doing online search for potential ideas, running under the moniker “Su-125”, apparently created by someone called “Bispro” and published at DeviantArt in 2010; check this: (www.deviantart.com/bispro/art/Sukhoi-Su-125-Foghorn-15043...). The rendition shows a Su-25 with its engines re-located to the rear fuselage in separate nacelles, much like an A-10, plus a T-tail. However, as many photoshopped aircraft, the shown concept had IMHO some flaws. Where would a landing gear go, as the Su-125 still had shoulder wings? The engines’ position and size also looked fishy to me, quite small/narrow and very far high and back – I had doubts concerning the center of gravity. Nevertheless, I liked the idea, and the idea of an “A-10-esque remix” of the classic Frogfoot was born.

This idea was fueled even further when I found out that the Hobbycraft kit lends itself to such a conversion. The kit itself is not a brilliant Su-25 rendition, there are certainly better models of the aircraft in 1:72. However, what spoke for the kit as whiffing fodder was/is the fact that it is quite cheap (righteously so!) and AFAIK the only offering that comes with separate engine nacelles. These are attached to a completely independent central fuselage, and this avoids massive bodywork that would be necessary (if possible at all) with more conventional kits of this aircraft.

Another beneficial design feature is that the wing roots are an integral part of the original engine nacelles, forming their top side up to the fuselage spine. Through this, the original wingspan could be retained even without the nacelles, no wing extension would be necessary to retain the original proportions.

Work started with the central fuselage and the cockpit tub, which received a different (better) armored ejection seat and a pilot figure; the canopy remained unmodified and closed, because representing the model with an open cockpit would have required additional major body work on the spinal area behind the canopy. Inside, a new dashboard (from an Italeri BAe Hawk) was added, too – the original instrument panel is just a flat front bulkhead, there’s no space for the pilot to place the legs underneath the dashboard!

In parallel, the fin underwent major surgery. I initially considered an A-10-ish twin tail, but the Su-25’s high “tail stinger” prevented its implementation: the jet efflux would come very close to the tail surfaces. So, I went for something similar to the “Su-125” layout.

Mounting the OOB stabilizers to the fin was challenging, though. The fin lost its di-electric tip fairing, and it was cut into two sections, so that the tip would become long enough to match the stabilizers. A lucky find in the scrap box was a leftover tail tip from a Matchbox Blackburn Buccaneer, already shortened from a former, stillborn project: it had now the perfect length to take the Su-25 stabilizers! To make it fit on the fin, an 8mm deep section was inserted, in the form of a simple 1.5mm styrene sheet strip. Once dry, the surface was re-built with several PSR layers. Since it would sit further back on the new aircraft’s tail, the stinger with a RHAWS sensor was shortened.

On the fuselage, the attachment points for the wings and the engine nacelles were PSRed away and the front section filled with lots of lead beads, hoping that it would be enough to keep the model’s nose down.

Even though the wings had a proper span for a re-location into a low position, they still needed some attention: at the roots, there’s a ~1cm wide section without sweep (the area which would normally cover the original engine nacelles’ tops). This was mended through triangular 1.5 mm styrene wedges that extended the leading-edge sweep, roughly cut into shape once attached and later PSRed into the wings’ surfaces

The next construction site were the new landing gear attachment points. This had caused some serious headaches – where do you place and stow it? With new, low wings settled, the wings were the only logical place. But the wings were too thin to suitably take the retracted wheels, and, following the idea of a retrofitted existing design, I decided to adopt the A-10’s solution of nacelles into which the landing gear retracts forward, with the wheels still partly showing. This layout option appears quite plausible, since it would be a “graft-on” solution, and it also has the benefit of leaving lots of space for underwing stores, since the hardpoints’ position had to be modified now, too.

I was lucky to have a pair of A-10 landing gear nacelles at hand, left over from a wrecked Matchbox model from childhood time (the parts are probably 35 years old!). They were simply cut out, glued to the Su-25 wings and PSRed into shape. The result looked really good!

At this point I had to decide the model’s overall layout – where to place the wings, the tail and the new engine nacelles. The latter were not 1:72 A-10 transplants. I had some spare engine pods from the aforementioned Matchbox wreck, but these looked too rough and toylike for my taste. They were furthermore too bulky for the Su-25, which is markedly smaller than an A-10, so I had to look elsewhere. As a neat alternative for this project, I had already procured many moons ago a set of 1:144 resin PS-90A engines from a Russian company called “A.M.U.R. Reaver”, originally intended for a Tu-204 airliner or an Il-76 transport aircraft. These turbofan nacelles not only look very much like A-10 nacelles, just a bit smaller and more elegant, they are among the best resin aftermarket parts I have ever encountered: almost no flash, crisp molding, no bubbles, and perfect fit of the parts – WOW!

With these three elements at hand I was able to define the wings’ position, based on the tail, and from that the nacelles’ location, relative to the wings and the fin.

The next challenge: how to attach the new engines to the fuselage? The PS-90A engines came without pylons, so I had to improvise. I eventually found suitable pylons in the form of parts from F-14A underwing missile pylons, left over from an Italeri kit. Some major tailoring was necessary to find a proper position on the nacelles and on the fuselage, and PSRing these parts turned out to be quite difficult because of the tight and labyrinthine space.

When the engines were in place, work shifted towards the model’s underside. The landing gear was fully replaced. I initially wanted to retain the front wheel leg and the main wheels but found that the low wings would not allow a good ground clearance for underwing stores and re-arming the aircraft, a slightly taller solution was necessary. I eventually found a complete landing gear set in the scrap box, even though I am not certain to which aircraft it once belonged? I guess that the front wheel came from a Hasegawa RA-5C Vigilante, while the main gear and the wheels once belonged to an Italeri F-14A, alle struts were slightly shortened. The resulting stance is still a bit stalky, but an A-10 is also quite tall – this is just not so obvious because of the aircraft’s sheer size.

Due to the low wings and the landing gear pods, the Su-25’s hardpoints had to be re-arranged, and this eventually led to a layout very similar to the A-10. I gave the aircraft a pair of pylons inside of the pods, plus three hardpoints under the fuselage, even though all of these would only be used when slim ordnance was carried. I just fitted the outer pair. Outside of the landing gear fairings there would have been enough space for the Frogfoot’s original four outer for pylons, but I found this to be a little too much. So I gave it “just” three, with more space between them.

The respective ordnance is a mix for a CAS mission with dedicated and occasional targets. It consists of:

- Drop tanks under the inner wings (left over from a Bilek Su-17/22 kit)

- A pair of B-8M1 FFAR pods under the fuselage (from a vintage Mastercraft USSR weapon set)

- Two MERs with four 200 kg bombs each, mounted on the pylons outside of the landing gear (the odd MERs came from a Special Hobby IDF SMB-2 Super Mystère kit, the bombs are actually 1:100 USAF 750 lb bombs from a Tamiya F-105 Thunderchief in that scale)

- Four CBU-100 Rockeye Mk. II cluster bombs on the outer stations (from two Italeri USA/NATO weapon sets, each only offers a pair of these)

Yes, it’s a mix of Russian and NATO ordnance – but, like the real Georgian Su-25KM “Scorpion” upgrade, the TAM-1 would certainly be able to carry the same or even a wider mix, thanks to modified bomb racks and wirings. Esp. “dumb” weapons, which do not call for special targeting and guidance avionics, are qualified.

The gun under the nose was replaced with a piece from a hollow steel needle.

Painting and markings:

Nothing unusual here. I considered some more “exotic” options, but eventually settled for a “conservative” Soviet/Russian-style four-tone tactical camouflage, something that “normal” Su-25s would carry, too.

The disruptive pattern was adapted from a Macedonian Frogfoot but underwent some changes due to the T-tail and the engine nacelles. The basic tones were Humbrol 119 (RAF Light Earth), 150 (Forest Green), 195 (Chrome Oxide Green, RAL 6020) and 98 (Chocolate) on the upper surfaces and RLM78 from (Modelmaster #2087) from below, with a relatively low waterline, due to the low-set wings.

As usual, the model received a light black ink washing and some post-shading – especially on the hull and on the fin, where many details had either disappeared under PSR or were simply not there at all.

The landing gear and the lower areas of the cockpit were painted in light grey (Humbrol 64), while the upper cockpit sections were painted with bright turquoise (Modelmaster #2135). The wheel hubs were painted in bright green (Humbrol 101), while some di-electric fairings received a slightly less intense tone (Humbrol 2). A few of these flat fairings on the hull were furthermore created with green decal sheet material (from TL Modellbau) to avoid masking and corrections with paint.

The tactical markings became minimal, matching the look of late Georgian Su-25s. The roundels came from a Balkan Models Frogfoot sheet. The “07” was taken from a Blue Rider decal sheet, it actually belongs to a Lithuanian An-2. Some white stencils from generic MiG-21 and Mi-8 Begemot sheets were added, too, and some small markings were just painted onto the hull with yellow.

Some soot stains around the jet nozzles and the gun were added with graphite, and finally the kit was sealed with a coat of matt acrylic varnish.

A major bodywork project – and it’s weird that this is basically just a conversion of a stock kit and no kitbashing. A true Frogfoot remix! The new engines were the biggest “outsourced” addition, the A-10 landing gear fairings were a lucky find in the scrap box, and the rest is quite generic and could have looked differently. The result is impressive and balanced, though, the fictional TAM-1 looks quite plausible. The landing gear turned out to be a bit tall and stalky, though, making the aircraft look smaller on the ground than it actually is – but I left it that way.

1:72 Saab J 19B; aircraft ‘31’ of the Flygflottilj 3 (F 3) 3rd Division, Flygvapnet (Swedish Air Force); Lidköping, early 1941 (Whif/Hobby Boss kit conversion) by Dizzyfugu

+++ DISCLAIMER +++

Nothing you see here is real, even though the conversion or the presented background story might be based historical facts. BEWARE!

Some background:

The Swedish Air Force was created on July 1, 1926 when the aircraft units of the Army and Navy were merged. Because of the escalating international tension during the 1930s the Air Force was reorganized and expanded from four to seven squadrons. When World War II broke out in 1939 further expansion was initiated and this substantial expansion was not finished until the end of the war.

Although Sweden never entered the war, a large air force was considered necessary to ward off the threat of invasion and to resist pressure through military threats from the great powers. By 1945 the Swedish Air Force had over 800 combat-ready aircraft, including 15 fighter divisions.

At the onset of World War II, the Swedish Air Force (Flygvapnet) was equipped with largely obsolete Gloster Gladiator (J 8) biplane fighters. To augment this, Sweden ordered 120 Seversky P-35 (J 9) and 144 P-66 Vanguard (J 10) aircraft from the United States. However, on 18 June 1940, United States declared an embargo against exporting weapons to any nation other than Great Britain. As the result, the Flygvapnet suddenly faced a shortage of modern fighters. Several other foreign alternatives were considered: the Finnish VL Myrsky and Soviet Polikarpov I-16 were unsatisfactory, and while the Mitsubishi A6M Zero was available, delivery from Japan was impractical. The only way out appeared to be a modern, indigenous fighter aircraft.

The origins of the Saab 19 date back before the onset of WWII. Just in time for the American embargo, Saab presented to the Ministry on Sep 4th 1939 a fighter that had been meant to replace the obsolete Gloster Gladiators. The aircraft carried the internal development code ‘L-12’ and had been designed in collaboration with US engineers in Sweden, who were to aid with license production of Northrop 8-A 1s and NA-16-4 Ms.

The L-12 looked very much like the contemporary, Japanese Mitsubishi A6M “Zero”. The aircraft was a very modern all-metal construction with fabric-covered control surfaces. The L-12 was to be powered by a 1.065 hp Bristol Taurus and maximum speed was calculated to be 605 km/h. Its relatively heavy armament consisted of four wing-mounted 13.2mm guns and two synchronized 8 mm MGs on top of the engine, firing through the propeller arc.

The design was quickly approved and the new aircraft was to be introduced to the Flygvapnet as the ‘J 19A’. Production aircraft would be outfitted with a more powerful Bristol Taurus II, giving 1.400 hp with 100-octane fuel and pushing the top speed to 630 km/h. But the war’s outbreak spoiled these plans literally over night: the L-12 had to be stopped, as the intended engine and any import or license production option vanished. This was a severe problem, since production of the first airframes had already started at Trollhättan, in the same underground factory where the B 3 bomber (license-built Ju-86K of German origin with radial engines) was built. About 30 pre-production airframes were finished or under construction, but lacked an appropriate engine!

With only half of a promising aircraft at hand and the dire need for fighters, the Swedish government decided to outfit these initial aircraft with non-license-built Wright R-2600-6 Twin Cyclone radial engines with an output of 1.600 hp (1.194 kW). The fuselage-mounted machine guns were deleted, due to the lack of internal space and in order to save weight, and the modified machines were designated J 19B. This was only a stop-gap solution, though. P&W Twin Wasp engines had also been considered as a potential power plant (resulting in the J 19C), but the US didn't want to sell any engines at that time to Sweden and this variant never materialized.

An initial batch of 24 J 19B aircraft was eventually completed and delivered to F3 at Lidköping in late 1940, while airframe construction was kept up at small pace, but only seven more J 19Bs were completed with R-2600 engines. Uncompleted airframes were left in stock for spares, and further production was halted in mid 1941, since the engine question could not be solved sufficiently.

The J 19B proved to be a controversial aircraft, not only because of its dubious engine. While it was basically a fast and agile aircraft, the heavy R-2600 engine was rather cumbersome and not suited for a fighter. Handling in the air as well as on the ground was demanding, due to the concentration of weight at the aircraft’s front – several J 19Bs tipped over while landing.
As a consequence, the J 19B simply could not live up to its potential and was no real match for modern and more agile fighters like the Bf 109 or the Spitfire – but the Swedish equipment shortages kept the machines in service throughout WWII, even though primarily in a ground attack role and fulfilling other secondary line duties.

Towards the end of WWII, the J 19’s intended role was eventually filled by the indigenous FFVS J 22 fighter – ironically, it could be outfitted with a license-built P&W Twin Wasp. By that time about forty J 19 airframes were more or less complete, just lacking a proper engine. Mounting the now available Twin Wasp to these had seriously been considered, but the aircraft’s performance would not suffice anymore. Consequently, a thorough modification program for the J 19 was started in late 1944, leading to the highly modified post-WWII J 19D with a liquid-cooled Packard engine.

No J 19 ever fired in anger during WWII or was involved in battle, since Sweden remained neutral and stayed out of any conflict with its neighbors at war. Another major problem for the Swedish Air Force during World War II was simply the lack of fuel: Sweden was surrounded by countries at war and could not rely on imported oil. Instead, domestic oil shales were heated to produce the needed petrol, which was rather allocated to the interceptor units, though.

After WWII, the remaining dozen J 19Bs were kept in service and soldiered on until 1948, when all remaining aircraft were scrapped. Additionally, Wright was also paid the overdue license fees for the originally unlicensed engines. The late-war J 19D served on for some time, though, together with the J 26 fighters, until 1950, when both were replaced by de Havilland Vampires and the Swedish Air Force underwent a rapid modernization into the jet age.

The kit and its assembly

The Saab J 19 never saw the hardware stage, but it was a real life project that was actually killed through the outbreak of WWII and the lack of engines. Anyway, it was/is called the “Swedish Zero” because it resembled the Japanese fighter VERY much – wing shape, fuselage, even the cockpit glazing! Since I had an unused Hobby Boss Zero (a late model) in store, I decided to build a personal J 19 whif, just in case it would have entered service…

Much of the Zero was taken OOB – Hobby Boss kits are of simple construction, but they have thick/massive material which makes conversions rather difficult, so I changed anything that was easy to handle. This includes:

● A new R-2600 engine, from a Matchbox B-25 Mitchell bomber

● New horizontal stabilizers from a Matchbox Brewster Buffalo

● A new propeller with spinner

● Main landing gear was inverted, so that the wheel discs face inwards

● Wheels from a Brewster Buffalo

● New retractable tail wheel, from a P-51 Mustang

● A Matchbox pilot was added to the cockpit, as well as some details

Painting and markings

I did not want to use a typical olive green/light blue Swedish livery on this one, even though it would have been the most suitable option. Furthermore, I would not fall for the popular splinter scheme (Viggen style), which would by far not have been appropriate for the intended early WWII era. What to do…?

I did some legwork and found the Swedish B 3 bombers (Ju 86K), which were actually produced in Trollhättan under license in the late 30ies These wore various camouflage schemes, including German RLM colors, even the pre-WWII Luftwaffe splinter scheme in RLM 61, 62, 63 and 65. That made me curious, since I expected the colors to have a sharp contrast and make the Swedish and squadron markings stand out – but I did not go for the splinter look, I rather based my livery on a late B 3 scheme.

Painting was done with free hand and brushes, using Model Master enamels from the Authentic range, namely 2075 Dunkelbraun, 2076 Grün, 2077 Hellgrau and 2078 Hellblau as basic tones. These semi-gloss enamels are – in contrast to the other WWII RLM tones from the brand – easy to use and create a very fine finish.

Some weathering was done through dry-painting with lighter shades on the panels and leading edges, and a thin black ink wash was applied in order to emphasize the fine recessed panel lines of the Hobby Boss kit. Later some smoke and soot stains were added with dry-brushed matt black.

Only a few decals were applied: the Swedish roundels come from a TL Modellbau aftermarket sheet, the code numbers on nose and tail from a Swedish Fiat CR.42 Falco. The yellow color on the propeller boss was generally associated with a 3rd squadron, and the ‘3’ on the fuselage was lent from an Airfix Saab Draken. Plain and simple.

In the end, a simple whif, and it still looks a lot like a Zero – but so did the J 19! I am not truly happy with the RLM tone cammo, it almost looks like a winter scheme? But after taking pics with a forest background, both scheme and colors seem very appropriate for that environment, blending shapes. And it looks far more interesting than a pure olive green aircraft, doesn’t it?

As a side note: if you ever consider building a Star Trek Klingon ‘Bird of Prey’, consider RLM 62 as you basic color of choice!

Some background

After Mil Helicopters' Mi-28 combat helicopter did not find takers, the design bureau decided in the 2000s to take a huge development step forward and question the basic helicopter layout. The result was the Mil Mi-62 (NATO reporting name: Hepcat), a single-seat attack gyrodyne/compound helicopter: a VTOL aircraft with a helicopter-like rotor system that is driven by its engine for take-off and landing but basically relies on conventional means of propulsion to provide forward thrust during cruising flight. Lift during forward flight is provided by a combination of the rotor, like an autogyro, as well as conventional wings, even though these alone would not keep the aircraft in the air.

The Mi-62 featured a tip-jet-powered rotor that burned a mixture of fuel and compressed air, bled from two wing-root-mounted jet engines. The rotor was only driven during the start/landing phase and at low speed. The air for the rotor was produced by compressors driven through a clutch off the main engines, though, which was fed through ducting up to the rotor head. Two Progress AI-222-25 turbofans, each rated at 24.52 KN (5.512 lbf), provided thrust for translational flight while the rotor autorotated, enabling VTOL and STOL start with overload. The cockpit controls included a cyclic and collective pitch lever, as in a conventional helicopter.

Each engine supplied air for a pair of opposite rotor blades. The rotor blades were a symmetrical airfoil around a load-bearing spar. The airfoil was made of carbon fiber and light alloy because of center of gravity concerns. The compressed air was channeled through three tubes within the blade to tip-jet combustion chambers, where the compressed air was mixed with fuel and burned, driving the rotor. As a torque-less rotor system, no anti-torque correction system was required. Propeller pitch was controlled by the rudder pedals for low-speed yaw control. To support handling at low speed, bleed air from the main engines was also ducted to a control vent system in the tail.

Transition from helicopter to autogiro took place at around 60 mph by extinguishing the tip-jets, and at higher speeds up to half the lift was provided by the fixed wings. At high cruising speed, the Mi-62 almost behaved like a standard aircraft. Cruising speed was to be at about 500 km/h (312 mph), coupled with a range of up to 1400 km (870 ml).

Since the speed of the advancing rotor tip is a primary limitation to the maximum speed of a helicopter, this arrangement allowed a faster maximum speed than pure helicopters such as the Mi-24/35 or the AH-64. The elimination of the tail rotor is a qualitative advantage, too, because the torque-countering tail rotor can use up to 30% of engine power. Furthermore, the vulnerable boom and rear gearbox are fairly common causes of helicopter losses in combat. The Mi-62’s entire transmission presents a comparatively small target to ground fire, and is a rather simple/rigid arrangement with much less moving parts than a standard helicopter.

The Mi-62 was designed as an alternative to Kamov's successful Ka-50/52 program, and regarded as a heavier alternative. While the Ka-50 was designed to be small, fast and agile to improve survivability and lethality, the Mi-62 was to rely on speed, quick acceleration and decelleration as well as on good low altitude handling, coupled with sufficient protection against small caliber weapons. Since operation would be primarily at low level and using the landscape as cover, not much emphasis was put on stealth features, even though many passive protection elements like RAM were incorporated into the aircraft.

One of the program priorities was to enhance the helicopter's survivability. With this goal in mind, the configuration and systems' arrangement were chosen, assemblies designed, and structural materials tested, beyond the robust rotor propulsion system. The following measures to enhance pilot survivability were taken:

• Engines were placed on both sides of the airframe to prevent a single hit from destroying both engines
• The gyroplane could fly on a single engine in various modes – even with a damaged rotor a controlled landing glide was possible
• The cockpit was armored and screened with combined steel/aluminum armor and armored Plexiglas
• The hydraulic steering system compartment was armored and screened
• Vital units were screened by less important ones
• Self-sealing fuel tanks were filled with polyurethane foam
• Composites were used to preserve the helicopter's efficiency when its load-carrying elements are damaged
• A two-contour rotor-blade spar was developed, integrating the air ducts
• Control rod diameter was increased by positioning most of them inside the armored cockpit
• The powerplant and compartments adjacent to the fuel tanks were fire-protected
• The hydraulic system is capable of operating for 30 minutes if the oil system is damaged
• The power supply systems, control circuits etc. were made redundant and placed on opposite sides of the airframe

The armor consisted of spaced-aluminum plates with a total weight of more than 300 kg. The armor is fitted into the fuselage load-bearing structure, which reduces the total weight of the helicopter. GosNIIAS tests confirmed the pilot's protection up to 20mm caliber cannon rounds and shell fragments.

Another unique feature of the Mi-62 is the use of a rocket-parachute ejection system in case of an emergency. The helicopter emergency-escape system uses the K-37-800 ejection seat that was developed by the Zvezda Scientific Production Association (Chief Designer Guy Severin). The pilot's safety was also ensured by the undercarriage design. The undercarriage is capable of absorbing large loads in an emergency landing, and the cockpit has a crunch zone of up to 10-15% upon impact.

Basic armament consists of a twin-barreled Sh2A42 30-mm gun. The gun is mounted in a shallow turret which can rotate full 360° near the center of fuselage. It has 460 rounds of ammunition, firing high-fragmentation, explosive incendiary rounds and armor-piercing rounds.
The cannon has a dual-feed, which allows for a cyclic rate of fire between 300 to 900 RPM. Its effective range varies from 1500 meters for ground vehicles to 2,500 meters for air targets. Stated penetration for the 3UBR8 is 25 mm of RHA at 1,500 meters.

Beyond that, the aircraft carries a substantial load of weapons in six external hardpoints under the stub wings. An total of some 2.000 kg mixed ordnance, including AAMs, AGMs, gun and unguided rocket pods which include the S-13 and S-8 rockets, can be carried. Even unguided and guided (IR, optical, laser) bombs have been successfully tested, so that the Mi-62 could eventually replace early Su-25 combat aircraft in the CAS role. The "dumb" rocket pods can be upgraded to laser guided with the proposed Ugroza system.

The main armament against moving ground targets consists of up to sixteen laser-guided Vikhr anti-tank missiles (transl. Vortex or whirlwind) with a maximum range of some 8 km. The laser guidance is reported to be virtually jam-proof and the system features automatic guidance to target, enabling evasive action immediately after missile launch.

Like the Ka-50, the Mil gyrodyne was from the outset to be operated by a single pilot only. Mil’s designers concluded after thorough research of helicopter combat in Afghanistan and other war zones that the typical attack mission phases of low-level approach, pop-up target acquisition and weapon launch would not simultaneously demand navigation, maneuvering and weapons operation of the pilot. Thus, with well-designed support automation, a single pilot was expected to carry out the entire mission alone.

During operational testing from 1995 to 1996 the workload on the pilot was found to be similar to that of a fighter-bomber pilot, and the pilot could perform both flying and navigation duties. Later flight tests of the Mi-62 prototypes proved that its handling was more like an aircraft with VTOL capabilities than a standard helicopter, so that jet pilots could master it with some training.

Initially the Mi-62 was to be have been fitted with the Merkury Low-Light TV (LLTV) system. Due to a lack of funding, the system was late and experienced reliability and capability issues. As a result, focus shifted to Forward Looking Infra-Red (FLIR) systems, including the Shkval-N sighting system with an infrared sensor. Many versions were tried; on some the original "Shkval" was supplemented by a thermal imaging system, while others saw a complete replacement by the "Samshit" day-and-night system, which has become the final sensor standard, mounted in a chin sensor turret.

The fire control system automatically shares all target information among the four Mi-62 of a typical flight in real time, allowing one helicopter to engage a target spotted by another, and the system can also input target information from ground-based forward scouts with personnel-carried target designation gear.

The Mi-62 was, after a lengthy development and constant lack of funds, eventually adopted for service in the Russian army in 2015. It is currently manufactured by the new Russian Helicopters company that was founded in 2009 in Moscow, and built at the Mil Moscow Helicopter Plant. It has been introduced to both Air Force (Mi-62 sans suffix, ‘Hepcat A’) and Naval Aviation (Mi-62K, ‘Hepcat B’) and is being used as a heavily armed attack helicopter against both ground and airborne targets.

The navalized Mi-62K derivative has been selected as the new ship-borne attack type for the Russian Naval Aviation (Aviatsiya Voenno-morskogo Flota Rossii). It will feature folding rotor blades and life-support systems for the crew, who will fly in immersion suits. The fuselage and systems will be given special anti-corrosion treatment and a new fire-control radar will be capable of operating in "Sea Mode" and of supporting anti-ship missiles. Aviatsiya Voenno-morskogo Flota Rossii will need no fewer than 20 Mi-62, which will be operated together with Ka-52Ks.

The first Mi-62K is tentatively slated to enter squadron service by late 2014 or early 2015, coinciding with the delivery of the first carrier of the new Mistral class amphibious assault ships, ordered by the Russian Defense Ministry. These small carriers will contain rotary-wing assets, formed into aviation groups, and each of these groups is planned to include eight attack and eight assault/transport helicopters.

The kit and its assembly:

Another entry for the “Za Rodinu - The Anthony P Memorial Build” at whatifmodelers.com, and this time it’s a modern and rather exotic whif. Helicopters are rare among whiffers, so I thought I’d give that subject a chance, and I actually had the basis kit in store for some time, as I intended to build it for another GB but never got that kick to start it.

The fictional Mi-62 is a conversion of a snap-fit kit from Kotobukiya from a series of generic, roughly 1:72 scale mecha vehicles that do not belong to a specific series or movie, but they seem to be intended to go well with Gundam or Dougram. These are rather toy-like, sturdy things, but they have potential for more – especially the gyroplanes (two different types exist).

These seem to be unmanned drones/UAVs, though, and that immediately leads to the conversions I made. Most important change is a manned cockpit with a clear canopy (from a KP Su-25) and the respective, scratched interior.

Another big change was the deletion of the original, gigantic gatling gun under the fuselage, replaced by a much smaller twin cannon turret. That left a lot of ground clearance – as a late modification I decided to chop the landing gear and the respective fin/wing endplates by more than 1cm, so that the gyroplane would sit closer to the ground.

Further small cosmetics include an asymmetrical radome and a protruding pitot boom, some antenna bulges, new engine exhausts, chaff dispensers in the fuselage flanks, and free-standing main wheels.

The ordnance comes from a Dragon Soviet-Air-To-Ground-Ordnance kit, hung onto six new wing hardpoints (from a 1:144 F-4E and an ESCI Ka-34 in 1:72, IIRC).

Painting and markings:

Choosing a proper scheme was tricky. The helicopter was to look realistic, but still exotic, at least for Russian standards. I considered various options:

● An all-mid-grey livery, inspired by current Mi-35 attack helicopters. Too dull & simple!

● A trefoil-style scheme in khaki and olive drab, with blue undersides. Flashy, but IMHO rather old-school.

I finally found an original scheme on a Ka-62 prototype (shown at MAKS-2009): a wraparound scheme in olive drab, medium grey and chocolate brown. The colors are enamels, I used Olive Drab ANA 613 (ModelMaster #2050), German Uniform “Feldgrau” (ModelMaster #2014) Grey and German Armor Red Brown (Humbrol 160), later highlighted through dry-brushing with lighter shades of the basic tones and a black ink wash, standard process.

The interior was to be Russian-style, too, but instead of the eye-boggling turquoise I went for PRU Blue (Humbrol 230) inside of the cockpit. Still looks odd, but it’s not so bright.

As a twist I decided to use Russian Navy markings – and the real world introduction of Mistral Class ships was a good excuse for a naval version of this attack helicopter. The Naval Aviation used to and does employ many land-based aircraft and helicopters, incl. e. g. the Mi-24, in similar liveries to the Air Force or Army cousins.

The markings were puzzled together from various aftermarket decal sheets from Begemot , Authentic Decals and TL Modellbau, as well as from the scrap box. After some additional dry-brushing with medium grey overall, the kit was sealed with a coat of matt acrylic varnish.
