If I leave my servo ATVs at 100% my cylic pitch in both aileron and elevator will cause binding at high pitch with the washout arms and outer swashplate ball arms. Did I set something up wrong or is it normal to have to adjust the ATVs down a bit?

TIA Ned

How far from center is the ball mounted on your servo horn?

If your cyclic and collective pitch is where you want it to be, an idea is to shorten the pushrods from the washout to the flybar cage about 1-1.5 mm. On several of my Hirobos(not the x-spec though) I have done that and sacrificed the 90 deg. angle on the washout to not have binding at extreme collective with cyclic pitch.

Thanks for the replies......
At the monment, I have +11 / -10 -- 0 at mid stick. At +4 both the wash-out arms and mixing arms are level. I have adjusted so many times I am seeing ball threads. I will have to adjust my elevator atvs for sure, but this setup seems to give the least interaction/binding. My servo wheel balls on elevator are at +-9mm from center. I know the more mechanical setup is spot on the better she will fly.

Thanks
Ned
