Hi there I have a Futaba 3GRFS 40mhz and a Futaba R103F receiver and I have a (40.675 RA; CH51) cystal I know how to change the frequency settings on the tx but it will not work and respond to the receiver, Do I need another crystal?
I could really do with a manual but I can only find 2.4ghz versions. Is there anyone out there that could help.
