rfi caused by the engine can this be stopped i have fitted a sheiled cap and it has made little differance,iam running am 27 meg and with the engine running and ariel fully up i am only getting about 30 feet range before the throttle and steering servos start to glitch ,i have tried a different receiver ,transmitter and different crystal set and with no other cars running ,so i would imagine that with more cars the worse it would be ,would simply changeing to fm cure all of the problems or would i still encounter the same problems,if it would cure it could some one explain why it would be cured thanx guys.
