Maybe the transmitter should be checked by JR service as well? I agree with other posters that that type of receiver should not be used with the radio.

For my Futaba gears, Radio-south and Futaba Service here are very good verifying air-worthy for receivers/radios. I have one FM receiver went dead as the plane making the final turn during the landing. The plane just dropped itself to the ground at 5 feet. The receiver was sent in and the diagonsis was intermittent connection. I ended up buying a new unit from the Service at the swap price. The crystal is verified OK. Note the receiver was checked normal after the 'minor' crash.
