So is there no way to limit the servo arm travel?

Again, my setup is good.
But my slider has to be way over towards the tail box in order to get the pitch/thrust I need to hold the tail.
And it holds well in this configuration.
I'm just worried what happens when I give it full right rudder input, with the stick, to rotate/piro the heli.

I don't know that the slider is rubbing the tail box in flight but it doesn't have far to go before it would.
On the bench, full right collective stick pins the slider against the tail box.
Maybe this isn't a problem, maybe I'm not explaining myself...maybe I just don't know.

I do understand now that Trav. Adj. will not help.
