RE: pull pull geometry
This was a great find. I was having some issues with my pull-pull resistance increasing near full travel - to the point where I was not able to make it full deflection (3" on my big monocoupe). I re-rigged the cables and introduced positive ackerman and voila!! Problem fixed. I now have a very smooth 3" rudder deflection with no binding. Wish I saw this thread weeks ago, I probably took a lot of life out of my servo!
This really works, you made a believer out of me!!
