I have a JR r700 reciever. When I plug in the rudder channel the servo twitches and the throws are jumpy. I tried all the other channels and different servos and it seems to be just that channel. Is this a common thing? Is it ready for the trash? Any advice is appreciated thanks.

did u check the battery?

I agree, check your battery. I have the R700 in my LT40, and it performs flawlessly.

If the battery is OK, I'd contact JR. Has the rx been in a crash? If so, send to back to JR for a check -up.

It was in a crash about a year ago. But it worked fine up until today. I am charging the bat in hopes that is all it is.

Anytime an rx is in a crash you should have it checked. There can be internal problems waiting to bite you during flight. Is your plane worth it?

Does it do it with the transmitter on? If not its okay, I have three and they all do it with the transmitter off, but are solid with the transmitter on.
