After contacting the people at Horizon hobbies apparently the JR single conversion reciever (not dual conversion crystal) is not compatable with the transmitter I have for futaba unless you open it up and modify it a little bit. They said I can send the controler into Futaba and they will modify it and then I have to get another set of crystals for the JR reciever. Its basicly a pain to get the micro jr reciever even though it is negative shift set up with the futaba radio. Sucks huh? Now I have to get a Futaba radio setup and probably try to return the reciever because its negative shift? This is such a pain.
