Well, there poses another problem. I believe if you get another Airtronics receiver, you're going to have to get another transmitter. I may be wrong, but I don't think a Futaba transmitter will work with an Airtronics receiver. I would just go ahead and spend the money for a new complete radio. You can get a Skysport 4 for like $130. 90% of the time the radio's going to outlast the plane anyways.
