RE: Exceed RC Rx question
Ch 3 is throttle for sure, ch4 is rudder. If your new plane's ESC doesn't have BEC then you must attach a bec to the B channel on the receiver.
Chan 1 is alieron and ch 2 is elevator. You might have to make changes on the radio's to reverse some of the channel for your new plane. The switches are located in front of the radio.
