Have a Great Planes SU 26, and mounted a Fuji 46.5. Getting inteference in the throttle servo but nothing else. I used gold rod on the throttle link, spaced everything at least 12" away from engine, grounded the elect. module to engine.......... Nothing else is glitching, just the throttle when it running, even replaced the servo. Is my module bad? Do I need to wrap my spark plug wire? Do I need a different spark plug? Do I need to install sometype of loop that kills rf noise? Flustered.........
