regarding your JR radio. it is not true that you will damage your radio when using it with aerofly professional. and also you do not have to switch on your JR radio when using it with aerofly professional. simply plug in the cable and the radio will turn on automatically. just make sure its set to PPM mode. some older pro cable didn't have the correct wiring for the JR X378 radio. you would have to do a slight modification to the cable for it to work. the newer ones should already be fixed.
