Servos - Coreless or Digital?
Ity also eliminates some radio problems. There was a guy with a trainer, using a futaba ppm reciever. That means, automatically, that it was negative shift. We did a test. He turned on his plane and radio, I turned on my plane and radio. His plane went Whacko, but mine was unnefected and i still had full control, not evel lockout. Less people (or so it seems) have pcm than do ppm, so it is just that extra litle bit of insurance.
