RE: Futaba 9c: lost radio link to 148DP receiver
I had a similar problem with a 7C and a R138DP , fueled it up ,range checked it ,then while trying to start it the receiver failed. After I fussed with batteries , checked the crystal , nothing. I switched the crystal with another plane and it worked , switched back and it still worked. Tat crystal and receiver have been shelved , can't quite trust them.
