We're building an experimental PA-12, using Dakota Cub wings. The Dakota wings use ailerons with the PA-18 shape, and they also use the -18 actuation horns rather than the -12 bellcrank. I'm at the stage of rigging control surfaces so looked up the control surface movement specs in the PA-12 and PA-18 TCDS. I was surprised to see the aileron specs are quite different. PA-18 has considerably less travel.
PA-12 is 31 deg up and 25 deg down.
PA-18 is 18 deg up and 18 deg down.
I know we can't obtain the -12 up/down differential with this system, so here is my question:
Is there is any reason we shouldn't increase the aileron travel to 25 or 28 deg both up and down? 28 deg would be the average of the -12 spec.
