I have a regular style 3 axis nex5 sized gimbal underneath my hexa, but in anything other than hovering, it's getting a lot of wobble through the yaw motor interface which I can't seem to get rid of. The manufacturer is telling me that on his Naza he drops the gains till it stops doing it. I'd like to avoid buying DJI if possible.
The yaw motor is hard mounted to a carbon plate which is attached to the rails with rubber grommets.
I've just tried lowering my tilt rate D to 26000 and angle P to 210 and D to 7000 to see if that'd fix it, but it didn't much. I'm wondering if any of you have a strategy for dealing with this sort of wobble? Which PIDs should I be changing? Should the Tilt angle PIDS be changed together, or would you keep the D up while lowering the P?
I spent hours last night checking and replacing motors that weren't running smoothly, and the props have been balanced and checked to be running smooth thinking that would fix the issue, but it didn't.
Thanks!
