JPX 240 Turbojet Model-Aircraft Engine built in France, circa 1992
Practical gas-turbine power for model aircraft became reality when Bryan Seegers of Arizona flew his miniature turbojet powered aircraft in 1988; it was the first jet powered model aircraft flown in the United States.
By 1992 commercially available miniature jet engines similar to this JPX 240, began to appear on the market. This engine burns propane fuel and can produce up to 13 pounds of thrust. Today’s model-jet engines burn gasoline or jet fuel and produce several times more thrust.
The first jet plane, a Heinkel He 78, flew in 1939. A jet engine has no propeller. It sucks in air at one end and burns it with fuel. Hot gases blast out the other end, thrusting the aircraft forwards.
