You have a 6 channel RX and a 4 channel TX......Not a problem....However I got an RX, a while back that had the sockets mis marked.....Channel 1 is ailerons, 2 is elevator, 3 is throttle, 4 is rudder.....The RX I got was backwards. If that was your case, you would have the motor plugged into channel 4 which would be rudder stick...Pat
