Ronin S-pan axis not stable in flashlight mode with motors locked

leongrdic

As you can see in the video, when the Ronin S is held in the flashlight mode, with the motors locked (trigger button being held), rotating the handle around its own axis causes the camera to pan randomly. If I rotate the handle a little bit faster (which I didn't want to replicate for the video), the gimbal loses it and starts rotating the camera in random directions fast and uncontrollably, almost damaging it.

I tried turning smoothtrack off for all three motors (and holding the trigger button) but it doesn't change the behaviour.
The gimbal was properly balanced and the balance test showed Excellent for all three axes. Also the motors were auto tuned before trying this.
I tried "Restoring Gimbal Setup" once and the problem still occured after.
Ronin S firmware is latest version (v1.8.0.70) and I tried refreshing the firmware through DJI Pro Assistant for Ronin which didn't help solve the problem.

Does anyone know why this might be occurring and if there are any solutions I could try? Thanks!
