S900 Vibrating and jumping

Hi,

I've just fitted a brushless gimbal to my S900 and when in flight the whole aircraft vibrates and jumps up and down and when you raise the gear it gets worse.

The gimbal is mounted using a plate which is mounted in the same way a Zenmuse is. The gimbal does sit lower than a zenmuse too with about 3-4 inches clearance from the ground.

I tried to lower and raise the gains, but nothing seemed to help get rid of the vibrations.

When i put the Zenmuse back on its smooth as silk!!!

Any ideas to try?

Thanks

That's pretty interesting -- that the gimbal would affect the S900 so dramatically. Can you post a video? May be some sort of balance issue, but I don't know.

If the gimbal is not working properly it can induce oscillations and cause you issues. Also is the new gimbal heavier or lighter? If so you would need to re-CG the helicopter.

Also weight would change the Gains and also the CG location...

When you change things on a rig there are a lot of adjustments needed.
