Hi all,
I have mounted a brushless gimbal to my Quad. It is a HK gimbal found here,
Due to my frame setup I have the controller board and motor mounts mounted directly to my frame with no rubber dampeners such that come with the gimbal. I find when I am at cruising speed the gimbal behaves erratically and has random movements.
When I remove the props it operates fine and at below take off speed it operates fine. My thoughts are that the vibration from the props is effecting the operation of the gimbal. What are your thoughts? Has anyone come across this before?
My props are balanced the best I can with a prop balancer however no luck. Any further suggestions? Do you think I need to utilise the gimbal vibration mounts?

In short, vibrations will effect any gimbal controllers gyro and accel. (The sensor mounted near the camera.)
If high speeds are the only problem causing the gimbal jitter the motors may not be powerful enough to compensate for the forces of the wind. If the motors are rated for a strong enough force then the problem may be induced by an imbalanced camera gimbal.
I am not 100% familiar with your specific camera gimbal but you can represent high winds by holding the quad in your hands and using either a strong fan blowing torwards the gimbal facing the camera or by moving the frame rapidly. If rapid movements causes gimbal jitter you have probably reached the maximum effect of the gimbal.
