Default RE: RE: FM or PCM??

PCM glitches will show up as a no-responce as opposed to an unwanted responce on a PPM system. No matter what you do, they'll still show up. If you notice them, that's another story. Any number of tricks can be done to hide your perception of those errors. Then again to the average RC user, they'd perceive PCM as being better, even though it's not. Because the average RC user can't perceive a PCM frame drop, and the average user CAN perceive the average PPM frame error. Just ***** at servo manufactors, a simple 3 point servo signal buffer could be introduced to eliminate something like 50% or more of all errors on a PPM system with an absurdly small delay (1ms or less) This cost is PENNIES per servo.
