DJO you should listen to NJSwede and not just dismiss him out of hand because of things you think are happening. If there really is a lot of interference there that could be an issue, but I still think another component could be the real issue and deserves to be checked out thoroughly. I have also had my esc shut off because of servos drawing too many amps. The whole thing will usually shut off including throttle so not having throttle response is not a cut and dry indicator of an rx lockout. In reality an rx lockout is extremely rare where there isn't some other issue that causes it. Getting 2.4 interference while flying fpv is normal in just about any environment. Cell phones, wifi, and wireless internet providers use the same frequencies and your fpv tx/rx uses a raw channel with no coding. I don't think that kind of normal interference would cause an rx lockout on spektrum or any other system.
As was stated before it is your $ and equipment but I personally recommend looking into things more deeply for a real cause. If you still come up empty then you may have a radio problem. Without checking you are risking future planes regardless of the radio system.
I'm not dismissing him. I'm saying that I had these same problems with two completely different planes with completely different servos, with different radios and different RXs. The one thing in common between the issues was that it was Spektrum.
Thanks for the info!
