I have .looked everywere for a answer on this and no luck. I have a JR XP652 and I am trying to get it to work with G3. My radio is six channels and when I go to Control Mapping it trys and makes me setup Dual Rate switches, and KNOB. My radio has these D/R on the top but there not really a dang channel so I shouldn't have to set these and there is no knob. So when I try to setup just Trottle, pitch, yall, & roll it overwrites my others settings trying to make me point out D/R & Knob. I was kinda upset about this since all I fly is helicopters and I cannot leave some of the settings out to leave my radio compatible to practice helicopter flying. If anyone knows a solution to this let me know. I know some of Knife Edge staff browse this forums so if you have a solution let me know I have been looking on your forums and others and no luck.
