as far as this is concerned....and this is only my opinion....to minimise the chance of reciever problems make sure you use a resistor plug. next use a braid around the plug lead and ground it at both ends. finally use a fully shielded sparkplug boot. this should help lessen the chance of you losing your aircraft because of ignition noise.

also dont use any metal fittings to connect your throttle servo to your carb. keep your reciever and throttle servo AT LEAST 12 inches away from your ignition system...this includes the battery and switch that is used in cdi systems.

i have personally had more success from using a pcm reciever than a normal fm reciever.
