I figured away to keep my thumbs under control. When I first had the problem, the VA said it was carpal tunnel. Yeah right. So they gave me the braces for both hands. Later it was connected to nerve damage related to agent orange. Anyways I dug out the braces, and modified them a little. I took the thumb strap and made it where it wraps around the thumb to apply pressure to the thumb. It pulls back slightly, and I can adjust the pressure needed to stop my thumb from shaking. I flew with this for the first time this am, and it works great. I think that with the TX tray it should make it event better. I am so happy that I will be able to fly. It does restrict the full rudder a little but not enough to worry about. Im not a 3d flyer anyways. So I should be fine. My next flite Ill add a camera, and send a video. Just remember Im new, and great at crashing.
