As the others have said, it's not compatible to your JR radio. For future reference Futaba and Hitec use negative shift while Airtronics and JR use positive shift in there receivers. This applies only to the 72 mhz radio systems and not to 2.4 ghz radios. For the 2.4 radios you must use the same receiver as transmitter as the radios are proprietary.
