Two months ago I bought a Futaba 7CAF on channel 23. I recently found out through my club that there is a guy that flies in his backyard close to the field that operates on the same channel and if I wanted to fly on that channel I would have to call him everytime I wanted to fly, which I'm not going to do. So I need to change channels. Is it possible to send the radio to futaba and have them change the channel or should I just try and sell it? Thanks.
