my Rotorpixel won't balance. It was fine then after A routine satellite calibration on the phantom - don't know if I caught the reset button on the back of the gimbal circuit board - but now the Rotorpixel shakes like it can't get a balance fix. I've re balance the gimbal using the back and side sliders so it's seems pretty much perfect but when I switch on it shakes all over the place. I tried contacting Keri and Rotorpixel through their web site and filled out the FAQ/contact form all to no avail. Has anyone had a similar problem?
