Rudder servo zero
I have a Futaba 6 channel radion, non computer, and my rudder servo is not zeroed. Is there any way I can go in the radio or the servo and change the zero setting. No matter which way I put the servo arm on the post it still comes out offset a little.
Also on my rudder pull pull system, how much tension should there be on the cables to the rudder?

Hi Jim,
Not familiar with Futaba but you should have a "sub-trim" menu for all channels. Get the arm as close as possible and then adjust your position using the rudder sub-trim feature.
As for the tension, you should have a fair amount but not so much that you are flexing the servo arm. Somewhere between playing a tune on it and having it flapping in the breeze is fine.

I've always been able to get the horn to line up be rotating it either 90 or 180 degrees on the output shaft.
Pull/pull cables should be snug, but not so tight they sing like a guitar string. Make sure you are using a BB servo with your pull/pull installation or you will wear out the final gear in short order.

Those 4 arm jobs are supposed to split a spline differently
evevey 90deg .mine dident either so I got a round one from lhs & drilled it where I wanted & cut away for clearance with a zona saw. Don't look like factory but is where i wanted to go.
