I'm having an issue with DJI through my dealer, The Drone Pros. My gimbal is defective, limp as a biscuit, less than one month old. It did work when I installed it for a couple of flights. So It's defective in my view, the dealer says make a video and will let DJI decide. DJI sez the filter makes the Zenmuse HD-2D heavier thereby breaking the Gimbal. Can this be true? I've seen videos with the Phantom 2 flying with the filter.
