I believe I have figured out a way to solve your problem.

I used 3 programmable mixers.
The first one is what makes the elevator deflect at down switch.
The second one is what makes the elevator deflect at the middle position.
The third one makes the flaps deflect at the middle posision.


I used mix 1. It should look as follows.
Mix: active
mas: flap
slv: elev
link: off
sw: c or whatever switch you want to use
posi: down
You then go to the first screen of the mix and put in whatever percentage of elevator you want.

Open mix 2. It should look like this
mix: active
mas: flap
slv: elev
link: off
sw c or the same one you used on number 1
posi: center
Then go to the first screen of the mix and input your elevator percentage there.

Open mix 3. It should look like this.
mix: active
mas: ofst
slv: flap
link: on
sw: c or whatever you used on number 1 and 2
posi: center.
Then go to the first screen of the mix and imput the percentage that you want of flap travel in the middle position.

If you have dual elevator servos you will need to have link on on the first two mixes.


That should accomplish what you are trying to do.
