Was checking out the GUI on my cheap 2 axis chinese gimbal and somehow reversed the pitch axis 180*. Not sure what happened and I've been over all with a fine tooth comb. I can basically hang the gopro from the arm now in the up position :) All is stabilized with good power and response. Used this little sucker for a few months now. Not sure why I had to tinker with it. Probably because I was able to use the GUI with the 3 axis gimbal with great success. But how did I do that?
