Do you have any of the electronics close to the electronic ignition, that would be my guess. It should be as far away as possible from the receiver servos ect.

do you have the firewall covered with sheet metal(this acts as an rf sheild)?no metal or wires going from the engine into the radio compartment including the cut off switches.

I had an elderly gentleman tell me one time to wrap the ignition module in aluminum foil. You might check the ground wire.

You probably have some metal to metal contacts that are vibrating or rubbing together when the engine is running. Make sure all metal to metal contacts are secure with no chance of movement against each other. If you are using a resistor spark plug and a non conductive throttle push rod, it is doubtful that the ignition system is causing the problem.

A flying buddy had a vibration glitching problem with a glow engine. He changed everything that could be changed including the radio with no results. He ended up putting chokes on the servo leads and the glitching stopped; never did find the problem.
