Default PPM or PCM, single or dual Conversion ?


I suspect that the PCM receiver has masked the problem rather than solved it. Do you have your fail safes set so that the motors go to idle? Setting fail safe that way allows you to know if the receiver is going into fail safe.

A PPM receiver will respond to short giltches and may move the servos wildy, while a PCM receiver will ignore short glitches and not move the servos, at the same time it is not responding to your inputs either. If the glitch persists then it will go into fail safe and move the servos to the fail safe position. With most radios, if you have not set up fail safe, the default choice is to leave the servos at the last good data position.

Suggest you do some investigating to see why your PPM receiver is glitching.
