ok i have a gws r-4P|| /H 4 channel reciever. now its 1, 2,3, and then 4/b, now i thought u plug the esc/battery into the 4th channel and then the others into 1,2,3, but i plugged the 3 servos into channels 1-3 and a temp. battery into the 4th, it works but the rudder on channel 3 is being controlled by throttle movement. do i need the esc plugged in/lipo into channel 4 for it to work properly!? help!!!!! i wanna fly this thing already!
