I have finally rebuilt my quad after a bad crash, which destroyed the roll arm. So I had the parts 3D printed and glued them together with Loctite 401. Seems to be fine, if expensive.
I now find that after about ten minutes the gimble has an attack almost like epilepsy, rolling around uncontrollably, mainly in the roll axis. Otherwise it behaves very well indeed. (RCtimer yaw motor, Walkera pitch and roll motors)
I suspect it might be that I had the motor power setting dialed up too high.
I have now set them all to 150.
Could somebody post their PID setting for reference please?
Would be much appreciated.
By the way I have the power from a 3S/4S regulated so that it is a maximum of just over 10V.
