looks like a good alternative. But there’s also an option to use joystick twist function as well if you have joysticks with it.
I don’t have a leg disability myself, but I don’t have the space to have a rudder pedal, and I don’t use rudder that often anyway since I only fly Airbus airliners, but if I do need rudder controls, I use my sidestick twist function which works just as well.
