I have decided to put in the OS FS 91. I was checking the throws on the elevator and noticed that the Right Elevator travels approx 5 -6 mm higher than the Left Elevator. Full down and the Left is 5 mm lower. I have the DX7 with AR7000 RX. I have the two elevator servo connected to 2 different channels. Right Elevator is connected to Elevator and the Left Elevator is connected to Aux2. I tried playing with the travel adjust and that changed it but now when I bring the stick back to center it is completely off. Someone told me that I can adjust that with the DX7 but How? Can some one help please.
