Programmin split elevator on Spektrum DX7

[TrikeFlyer]

One of the reasons I bought the DX7 was their advertisement said it has "servo sync" to operate 2 servos together. No where in the manual can I find how to program a second channel to operate the second servo on the elevator.

When I mixed the elevator channel with AUX2 , the AUX2 servo only travels one direction as it is not centered and I can not find a way to center it.

Anyone out there had this experience and found out how to make second servo track with the elevator servo???

Thanks for your help - Trike

I had no trouble with this. I mixed elevator to Aux 2, using pmix 5 or 6 (this allows trims to pass through) I then zeroed out the travel for Aux 2, then I went to the servo reversing reversed aux 2, then I went to the sub trim menu and sub trimed the servo.

I used the P mix amounts to match the throws, SW: on OFFSET: 0

My elevators match perfect

Thanks rolling thunder for the reply. What do you mean by "zeroing out" the travel???

How do I get the AUX2 servo to start in the middle of the travel instead of at the far end??

I was almost there but could not "center" the servo travel.

go to the travel adjustment for Aux 2 and make them 0 instead of 100.

Also be sure to inhibit the AUX2 switch and AUX2 trim. That is done in the setup menu.
