More information needed. Give chapter and verse on the installation and circumstances when glitches occur.

Make sure all your engine's ignition system, switches, wires etc. are well separated from your receiver/servos etc.

Make sure your throttling with a plastic (nyrod or something) throttle cable. Don't use a metal link.

Make sure no metal parts are free to vibrate against each other, make sure the engine's tight, muffler, etc.

Make sure the reciever's mounted in foam.

Those are good places to start.

If it is a mag engine,not electronic ignition, I had the same thing with my Fuji BT32. Tried everything , moving switches, changed freq, isolated servos, etc.. I fnally got a hint from an RCer in England......Get some braided shield, put it over spark plug lead and ground it to the engine.. Solved the problem. Range increased from 20 feet t0 in excess of 120 feet. I used some scrap TV cable I had laying around, but have heard the shielding is available commercialy, don't know where though. Good luck.
