I justbuilt a42% Extra with a Spectrum 7ch receiver and transmitter module in my Futaba 9CAP. All the servos jitter bad for a couple seconds when you turn on the airplane. Both the satellite and the master rec. bind to the transmitter in less than a second, but then all the servos twitch randomly for a couple seconds. It is getting longer it seems each time. After they settle down there is no way to get them to do it again. Even with the engine (DA 150) running. They do not care if the engine is running or not. This only happens on power up. I tried Li-ion batts, on 6.0V regs, and I tried Nimh 5 cell packs wired direct. Exact same results. Range check is normal, well beyond the 90 ft min. It happens at the field and in the garage. Did not do it at all for the first few days after install. I am eager to fly my new model but have this nagging feeling that I had better figure this out first. Anybody seen this before?

Have you tried rebinding the system after you did your setup & programming?
