Simple answer is no. Can't be done with a retract servo.

No. A retract servo is designed to, upon a signal, move to either end of its travel and stop automatically. There's no way to adjust one from the TX EPA. You must use servo arm and retract control horn holes to properly adjust the travel.

As stated above, no. On the bright side though, when at the end of travel and stopped, they draw zero load.

If you look at the retract mechanisim itself, measure the throw of the rod that the servo is driving.

Lets say that from full up and locked to full down and locked the rod moves for example 1"

Take a blank servo wheel and drill two holes, that far apart and 180 degrees apart on the wheel. That is where you want to attach your pushrods. Now the rods will move exactly that amount when the servo goes end to end.

Confirmed.
If further information to assist with installation of retracts is required, refer to sub sections "Servo - alterations, calculators, repairs, make an ESC or winch & FAQ." and "Retract Undercarriage, Flaps and payload release" on Alan's Hobby, Model & RC FAQ Web Links
