was wondering if someone could tell me how far would you consider a safe distance from the E.I. to the receiver . also can I put a throttle servo near the E.I. I am trying to locate the fuel tank on the CG there should be a large area in front of the tank to locate receiver battery and a servo or 2 like my retract actuator and throttle servos any input would be helpful this is my first gas plane so working out the kinks
