I currently have alpha 60 and I recently purchased an Ultra Stick .60 and I need another receiver for it. I have a JR XP6102 radio. It came with a PCM R770 receiver and I was wondering is that the only receiver I can use with my radio are is there other models that I can use. Those run around $100 and I been looking, it seems that the futaba receivers are a good bit cheaper. I just dont know if you can mismatch receivers are what. Do you think I should stick with the R770? Any help would be appreciated.

Thanks, Mike
