Andy, Thanks. Before I do a complete reset let me review my info. The Transmitter is set to Acro. The Wing type is set to 2 servos and the elevator is set to 2 servos. If the mix between Elev and Aux 2 is inhibited, the Aux 2 Elev servo does not move. If the mix is on, it does. The servo plug into the receiver is correct I believe because all other surfaces move correctly and the all of the receiver ports are being used.
