Big F-16 turbine jet flies well until the engine quits

Most jet model write-ups end with a tidy landing and everyone pleased. This F-16 goes the other way: it covers a whole session, from a ground run through a full aerobatic routine, right up to the failure every turbine pilot fears, the engine stopping mid-flight and leaving no thrust at a critical altitude.



The airframe is a 1/8 scale F-16 Fighting Falcon from a FlyEagle Jet kit, driven by an older-generation Kingtech 80 that uses gas starting. Taking off the top fuselage hatch reveals the micro-turbine, the speed controllers, receiver boards and wiring, plus transparent bottles holding fuel with a yellowish tint. The exhaust nozzle carries an illuminated LED afterburner ring.



The flying is the standout. Once the dorsal panel was secured, the model taxied across a mowed grass strip and lifted into clear skies. It then flew fast passes, banked turns, a stretch inverted and low sweeps over the field, all while a chase drone filmed from the air. An FPV drone tracking a large turbine jet is a detail worth praising on its own.



Then the session, flawless until that point, turned: the turbine cut abruptly and the jet came down off the runway in tall grass. Several people walked in and carried it to a paved path. The cause has not been stated, and Club d'Aéromodélisme de Ribérac asks viewers to offer their own theories. With the INTERCLUB 2026 meet in Ribérac set for June 27 and 28, I hope this airframe is back in the air by then.

Pairing an older-generation Kingtech 80 with a 1/8 scale airframe seems a sensible call to me; that class of turbine suits the size of the model. The transparent fuel bottles also strike me as clever, since the level is visible at a glance without opening anything. The trade-off in my view is appearance: with the top panel removed, the interior looks busy, with bottles, wiring and boards all sharing the same space.

How is the afterburner ring powered? I would like to know whether the LED ring in the nozzle draws from the receiver board or has its own supply, and how the maker controls the glow so it shows during the ground run alongside the heat haze.

The maker has not said how the ring is wired. The only detail shared about it is that the exhaust nozzle contains an illuminated LED afterburner ring, and that it was lit during the ground test along with the heat haze from the turbine. Anything beyond that would be guesswork on our part.

Before the INTERCLUB weekend in late June, I would suggest another bench run of the recovered turbine, done the same way as the earlier ground test with the heat haze and the lit ring to confirm all is well. If it runs cleanly there, a few calm circuits with plenty of altitude before any low passes would give a margin that the final descent clearly did not have.
