I spoke with the Technical Service folks at Horizon Hobby, distributors for JR Radios. I was told that I could buy a JR Sport ($149.95), which is the radio I wanted to buy all along, and Horizon Hobby will convert it over to Mode III at no charge. So now I have the choice between Futaba 6EXA and the JR Sport SX600. Both in my price range and both in Mode III. I'm a happy camper once again. All I need to do is make the decision which radio manufacturer to go with.

The statement that was made about my not being able to be an instructor or trainer. with my Mode III configuration is quite true. But I'm a long way from being able to do either and Father time will probably grab me before that happens.
