I'll get a few 5955 and see what I can discover. My programmer works as I described with a 5945, I reassured myself previous to my last post. I did not try a 5955 at that time. I don't have a 5995.

I agree with turning down the travel arc volume, 60 degrees is most desirable but you have to have the right linkage ratio to realize full travel and a linear response from the TX through to the servo. Also your ATV or End-Points should be nearly maxed out. Best setup is realized with programming the servos to the TX and model specific linkage and deflection needs.
