I have built a 3D model for OS 50 SX. Is 1 servo (S3001 or equivalent) enough for the elevators? I'll be using a regular Y pushrod with hardwood stick between the 6" - 8" metal rods on both ends. It has large elevators about 2/3rd of the total stab area.

The other option is 2 servos and pull pull setup on each elevator. But since the S3001 servo is not a high end one, I may have speed or centering difficulties between the 2 halves.

Weight is not a problem.
Any feedback would be appreciated.
