A couple of years ago I attended a Jet meet in Winamac, Indiana. It was called the Spiderman Jet Meet and was in October. There was a young guy who only had one usable arm. He was flying a Skymaster F18, with a Two Stick Tx that had a Single Stick Knob glued to the top of the Aileron/Elevator Stick. He used that for Rudder. He was a very good pilot.

In the 80's, I helped some pilots that only had Single Stick radios. Some of my fellow RC club members, today, have Ace Single Stick Tx's.
