Thanks fellows for the feedback,has given me some food for thought.I do have a GP simulator and have been working eith that do OK there problem seems to be when need quick response not as fast as am with thumb.Tried the neckstrap the other day need to get used to it as does help with that feeling might drop the transmitter and since at this time all my flying is on the water wouldn't want to do that,or step off dock while watching plane.Thanks much to all of you.Bob Moodie
