I hinged the tail today and here is a problem....The problem is in geometry. There is no way for both elevator halves travel the same distance when both servos travel the same angle. It is no good for precision flyng.
Sitting in the hotel room in the middle of nowhere (with high speed internet at least) I run some calculation on the original tail setup. I simulate the situation where at full servo deflection (45 degree) both elevators are at the same spot (holes in both servos are at the same distance from the stab). Servo horn and elevator horn is 1 inch long. I wanted to see that is the difference between both elevators halves between neutral and max deflection.
As you can see the maximum difference is at 35 degree at it is about 0.65 degree. The maximum relative difference is at 30 degree about 2%.
So it looks like it is not as much as I was affraid of. I might dump the idea of changing the servo setup and go with stock.
