I am building a sailplane that has a T tail with flexable pushrod inside. The problem is that the cable inside is too tight for my servos to move easily. I am considering putting bellcranks inside the Vertical fin instead of the flex cable. (the first bend is causing the problem it has to turn in 1/2 inch radius.).

Maybe it would be better to take the existing stab and turn it into a V-tail. Which I am happy to do if someone better than me thinks there is enough area to be effective.

The plane is a Bobcat.
