a buddy of mine has suffered a partial loss of a hand, and he is not able to fly with two hands. I've been looking to help him get back to flying gliders and I think he is ready to fly solo with one hand. The biggest challenge we see is the lack of rudder, and we think the perfect solution would be to find a 3D stick, similar to the stick with potentiometer, but with a self-centering proportional knob. Our idea:
Normal stick function for stab and ailerons, and self-centering potentiometer for rudder.
Possibly, a 3d or 4d stick like these would be very helpful:
