3GX rudder endpoint adjustment advice?

[hedge]

I hate to say it but I down graded again. Once I have a couple of spare days I will try again. The whole deal has made me refine and perfect the mechanicsl set up and the heli is working very well - better than before. My only issue with 3.1 is the interaction in tic-tocs which I believe 4.0 addresses. So as I say after a few weeks of flying I will try again.
