OK. My cameraman and I have owned an M-10 for a year now. Done some network television, and music videos. All good. We don't use the tool for everything, so I'm admitting I'm not a specialist. We got the Movi-15 a month ago, and just now getting it out of the box. We will use an Epic Dragon, as we did on the M-10, but for now I'm setting it up with a Canon T2i for simplicity. Balanced as I did with the M-10, felt good about it, and turned on power. IT HAD A MIND OF IT'S OWN, SPASMING LIKE A FISH ON ACID. TURNING AND TWISTING ALL OVER THE PLACE. I'm currently rebalancing, and feeling the need to try again, but before I do, and possibly cause permanent damage to the unit or myself, I am putting this out there.... What caused this??
