    Hey guys,

    Recently have been trying to tune in my gimbal for my GH3 and I'm having trouble finding a sweet spot on the Yaw axis. Roll and Tilt I've got pretty smooth but can't seem to figure out the yaw axis. The Alexmos guide/setup pdf doesn't share much on the Yaw axis so I'm looking for help here. Do I have to have the gimbal mounted to the copter? Curious if I should suspend the copter and then pick up and test on each setting change, so far I have been doing by hand without copter attached. Also need to know what ball park my PID settings should be since yaw have a little more weight to spin than Roll or tilt.

    Thanks guys, Any help much appreciated!
    Nick

    To answer your questions I think a little more info would help;

    Weight of camera?
    Tot Weight of Gimbal and camera?
    What gimbal?
    What gimbal motors?
    3s or 4s lipo?
    Alexmos or Martinez?
    Two cards or ad on 3rd axis.

    Regards.

    To start with, I think the 5208 motors will give more power with 4s lipo vs 3s.
