After 2 nights of trying to balance this thing I am ready to give up and return it. I have tried different cameras (all on the supported cameras list) and lenses and have done the hand balancing PERFECTLY each time. When the Ronin is turned on the roll begins to drift and drift and drift. If I try to "Auto Tune" The gimbal goes nuts and starts rocking all over the place and making the same terrible noise I have seen in many youtube clips.
I don't think I have a choice but to return it. Good luck trying to get DJI to write you back and assist you with your $3000 product.
