RE: Problem with Futaba 7C and Hitec Electron 6 FM
Last three thoughts, then I would say send the radio and receeiver to Hitec.
1) check to see that shift select is set properly for your receiver
2) Make sure you ahve not put the radio into PCM mode
3) Power off the radio. Remove the channel module. Reseat it. Power up.
That's all I have. Sorry!
