RE: Digital Servos on KingCat flaps?
My experiance suggests that an analog servo will still pull higher amps, but will "give" so to speak and not eat itself up.
This is somewhat the same situation why I suggest using an analog 4131 on nose wheel steering. If you hit a rut in the runway high speed, the analog servo won't eat itself up trying to hold against the rut. While an 8411 will pop that nylon gear trying to hold.
