RE: Single Stick TX verses 2 stick setup????
Single stick - I just think (but don't know) that it would be difficult to twist the stick (rudder input) without an inadvertant aileron or elevator input. I have never tried one though.
Dual stick - What I'm used to and it works well for me.
If there is one (single stick) available for you to try without endangering a plane you might do so. Maybe connected to a simulator? Or 3 mistakes high/buddy box.
