Does GY401 require digital servo?
Jason - thanks, that does help. I had problems on a plane that used all digital servos (hitec 5925s) and a Futaba PPM receiver. The range check was terrible and it glitched severely and randomly. Many people then told me you must use a PPM Rx with digital servos. So, I bought a PCM Rx and sure enough it fixed the problem. A local guy told me he tried a single digital T/R servo in his heli with non-PCM Rx and it caused glitching. I would rather use the 9253 if it really won't cause glitching problems. Mike.
