I am switching over to electric flight and have a great planes ultimate biplane with a electrifly 35-30-1250 outrunner , ss-35 esc and futaba electronics. The receiver is a 4 channel and on it it specifies that channel 4 is battery (esc wire). Well I connect it as stated and that channel 4 controls the motor the only deal is it uses the rudder on my remote and not the throttle portion of it while the throttle portion activates the rudder. everthing else is ok. Now if I hook up the battery wire to the channel 3 everything acts as it should. Does it hurt it to hook the battery up to channel 3? any ideas on what is going on?
