I am setting up a super flying king. This plane has two servo's for the two elevators. The plane also has flaps using only one channel. I have the one elevator servo in the elevator port of the receiver and the other in aux.2. I am using prog mix 1 to slave the aux servo to elevator. This works except the elevator trim on the radio will only actuate the elevator channel. I have the flap on the flap channel using the three positions. Any thoughts? Thank you in advance. -Tom


PS I am using conventional wing
