9 months the unit worked perfect, never crashed it or even came close to it. No hard landings at all. Fired her up today to go fly and i hear this clanking sound the camera is hitting the the body of the mavic. Looked it up online and there are many of these issues online. I see a video that shows you if you tilt the mavic to the right during startup the gimble will fire up. That works no overload but when I try to calibrate it it sticks at 73% and says failed calibration. It will not set the gimble up if I start up on a flat surface. There is no debris and the gimble moves smooth and free powered down. I am going to call helidirect monday to see if they will do anything. If they will not I guess it needs to go back to DJI for repair.
