    Hi,
    Overshooting or not?

    Do you know if there is a way to find if a oscillation of the gimbal is due to a over or a under gain?
    I mean when Roll for example oscillate how do you know if you have to increase or decrease the gain?
    Sure, on the table, the gimbal stay well tuned but in the air .....
    I think a lot of people know this problem. That's could be verry nice if a trick exist.

    If the gain is set too low I very much doubt you'll see any oscillation André -- when the gain is too low the gimbal lags behind the motion. The oscillation is as a result of the gain being too high for the given mass in motion and the gimbal overshoots, corrects for it, the correction overshoots, etc. That's the oscillation.
