I cant get my radio to work with my plane. Everything is new. Futaba 7CA Gws R4P ch 26 futaba shift, GWS pico servos. when I turn on the radio and plug in the battery nothing happens. no control at all on any channel. There is some erattic glitching(really bad) that sometimes goes away If I hold one of the sticks to one side. But there is nothing that even resembles control of the servos. The GWS reciever is stamped for futaba radios. It has the proper reciever(FM) and crystal. The TX battery is reading 10.2 volts. The lipo is straight off of the charger. The radio is set on PPM(factory default. The bad part is that it is all new. so I cant say for sure that its in the TX or the reciever. One thing I thought of trying was to talk to some of the guys at the flying field and find someone with a Futaba radio and switch the TX crystals between my radio and his for a non flying bench test. If My plane works with his radio then the problem is in my TX. and if my radio works with his plane but his radio doesent work with mine then the problem is in my reciever. And of course after the bench test we would put the TX crystals back in the proper radio so we dont have the feds after us. I really need some help on this. Thanks.

If your transmitter works normally with the Futaba receiver that came with it, then the problem is likely in your non-Futaba receiver. Some non-Futaba receivers just don't work with Futaba equipment. You may wish to contact the maker of your receiver to see if they know about incompatibilities with some Futaba transmitters.

I bought the TX by itself from servo city and the GWS reciever from ALLERC. The servos, ESC and BEC all were tested with my AM car radio when I was building the plane.

"tested with my AM car radio "

Your 7CAP is not AM radio !

Indy, he tested the servos and electonics that come out of the reciever, they dont care if it is am or fm. He merely used what he had to test those components.

This is what happens when you type faster than your brains works

I just re-read post, is by any chance radio set to PCM ? I remember when I did same when
using radio for sim and forgeting getting it back to PPM.

I switched the TX crystal with another futaba radio and everything works like it should. So I boxed up my NEW radio and sent it in for repair. not happy.
And yes it was set on PPM.

Hey Bill, did you guys get a chance to look at my radio yet? I got an email letting me know that it made it to you guys on tuesday. Just wondering.
