Imagine the following. We are programming a CCPM heli using 3 servos to control the swash. Assume that the servos used a not quite ideal. They move at slightly different speeds and they travel slightly different distances for the same servo output.
The radio that is going to be setup allows to calibrate a 5 point servo curve for each of the 3 servos. Starting with a straight line moving the 5 points slightly up or down from this line might compensate for the servos traveling different distances, thereby allowing for a perfectly level swash plate at each possible position of the collective stick.
Now to my question. How does one compensate for difference in speed? (if at all possible).
Thanks for any replies.
