This uninteresting shot shows how high my brother flew his quadcopter. It also shows roughly how far the quad dropped from the sky like a 1.4kg (~ 3lb) rock. The results were surprising.
The cause is somewhat unknown. We are guessing it was caused by a radio brown out but we failed to check the radio (the blinking orange LED) before disconnecting the battery. Using the Spektrum DX8 we used the range check feature and found out the receiver an OrangeRX 610 (6 channel) was poor it stopped after about 10m (~33 feet) from what I’ve read this should be closer to 30m (98 feet). We also did a range check using my radio gear: a Spektrum DX6i and an OrangeRX 910 (9 channel) it dropped out just over 30m.
I will attempt to edit and post the video shortly.

Enthusiasts of radio-controlled drones or UAV showed up for a small meet. Some had home-made machines and others had commercially manufactured machines. Everyone customizes their flying machines!

A quadcopter, also called a quadrotor helicopter, quadrotor, is a multirotor helicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed-wing aircraft, because their lift is generated by a set of rotors (vertically oriented propellers).
Unlike most helicopters, quadcopters use two sets of identical fixed pitched propellers; two clockwise (CW) and two counter-clockwise (CCW). These use variation of RPM to control lift and torque. Control of vehicle motion is achieved by altering the rotation rate of one or more rotor discs, thereby changing its torque load and thrust/lift characteristics.
Early in the history of flight, quadcopter (referred to as 'quadrotor') configurations were seen as possible solutions to some of the persistent problems in vertical flight; torque-induced control issues (as well as efficiency issues originating from the tail rotor, which generates no useful lift) can be eliminated by counter-rotation and the relatively short blades are much easier to construct. A number of manned designs appeared in the 1920s and 1930s. These vehicles were among the first successful heavier-than-air vertical take off and landing (VTOL) vehicles. However, early prototypes suffered from poor performance, and latter prototypes required too much pilot work load, due to poor stability augmentation and limited control authority.
More recently quadcopter designs have become popular in unmanned aerial vehicle (UAV) research. These vehicles use an electronic control system and electronic sensors to stabilize the aircraft. With their small size and agile maneuverability, these quadcopters can be flown indoors as well as outdoors.
There are several advantages to quadcopters over comparably-scaled helicopters. First, quadcopters do not require mechanical linkages to vary the rotor blade pitch angle as they spin. This simplifies the design and maintenance of the vehicle. Second, the use of four rotors allows each individual rotor to have a smaller diameter than the equivalent helicopter rotor, allowing them to possess less kinetic energy during flight. This reduces the damage caused should the rotors hit anything. For small-scale UAVs, this makes the vehicles safer for close interaction. Some small-scale quadcopters have frames that enclose the rotors, permitting flights through more challenging environments, with lower risk of damaging the vehicle or its surroundings.[8]
Due to their ease of both construction and control, quadcopter aircraft are frequently used as amateur model aircraft projects.
Een onbemand luchtvaartuig of "drone" is een luchtvaartuig zonder piloot aan boord. De toestellen worden vaak op afstand bestuurd, waarbij de bestuurder zich in de nabijheid kan bevinden, maar ook op duizenden kilometers afstand. Er zijn ook autonomere toestellen, die volgens een geprogrammeerde opdracht handelen.
Er bestaan verschillende namen waaronder een dergelijk toestel bekend is: UAV (Unmanned Aerial Vehicle) of RPAS (Remotely Piloted Aircraft Systems), Micro Air vehicle (MAV), Autonomous Aerial Robotics (AAR), Small Unmanned Aircraft System (SUAS), microcopter, mini UAV of small UAV, rotor-UAV of RUAV, Quadcopter.
In het Nederlands wordt ook wel eens het woord drone gebruikt. "Drone" is oorspronkelijk een militaire luchtvaartterm voor een onbemand vliegtuig dat dient als 'vliegend doel' om uit te schakelen bij oefeningen; het zijn vaak aangepaste voorheen bemande uitgefaseerde straaljagers zoals de F-16 Fighting Falcon en in de toekomst de F35 ofwel JSF. .

Following its world premiere at the Linz Klangwolke in September 2012, the Ars Electronica Futurelab’s (AT) computer-controlled swarm of four-rotor mini-whirlybirds—so-called quadcopters—took to the air again on Saturday, March 23, 2013 in a role and setting no less spectacular than the exciting technology itself: as high-tech heralds of Paramount’s “Star Trek – Into Darkness” that’s opening in movie theaters on May 9th. A squadron of 30 LED-studded AscTec Hummingbird quadcopters hovered above Potters Fields Park near London’s Tower Bridge and, in conjunction with Earth Hour, formed a three-dimensional Star Trek logo in the night sky.

What we have learnt about quadcopters and props:
- Experiment with props to find the ones that suit the quad the best
- These grey APC 10x4.7” props suit the quad better than the three bladed GWS 9050 we were using. The APS 10x4.7” props provide more lift, more stability and better handling response (the rudder was poor with the GWS). The motor KV/power, frame size and total weight and everything else all effect what size prop will best suit
- Props must be properly mounted and this can be painful. Prop adaptors, motor shafts and the hub of props must all be matched up to fit properly. This is probably where we have had problems before with other props. It doesn’t matter how well props are balanced if they are not mounted properly
- It almost goes without saying- balance the props
- Carry spare props: we have had some pretty major crashes with our quads and the parts we have broken the most are the props. Remember you’ll need pushers and pullers (or CW and CCW) as spares
The black board on the left was purchased as part of a quadcopter kit from Goodluckbuy. It’s a KK 5.5 board and only uses gyros to attempt to stabilise flight. One of the hardest things with this board is working out how to use it and setting it up. There is little feedback from the board and adjustments must be made using the pots. When something is wrong it’s very hard to work out what the cause is.
However the new board is completely different. The LCD display and buttons provide a complete menu system with diagrams of motor numbers and directions. It also uses gyros with additional accelerometers. I have high hopes for this board and making my quad easier for me to fly.
