I have this weird issue with my tilt motor. When I test it out by tilting the ronin-m quickly the camera stays level. But when I slowly tilt the camera down the gimbal not longer works to keep the camera level and it moves down to the floor with my movement. Here is a video to show what I'm talking about. I'm have a lot of issues with the tilt motor I suspect this ronin-m needs to be returned for a new one. Any advice would be appreciated, thanks  

Did you set the mode switch to the top on your remote?
Make sure your ronin-m is well balanced and up to date
