Okay I will admit that I did try to balance the Ronin SC with the phone mount right when I got the Ronin SC.  I had the Sony a6400 on it with the Sigma 16mm...and I could not get the gimbal to balance with the phone attached.  It was so frustrating.  I gave up and forgot about it.  Then my daughter wanted me to do some tracking of her for her kids YouTube video so I decided to finally figure it out.  It did take some time but I can now safely say I can balance the Ronic SC with the phone mount without any problems.  It's still a bit trick but it is possible.  Hopefully this video will help.  Don't get too frustrated.

Thanks for the insight!

Has anyone managed to get the sc balanced with a sony a7rii w/ a pixel 2 xl? Or am I asking for too much?
