One day I launched a Mavic 3 enterprise to 50 feet. It suddenly turned on it's own. I let the controllers go completely. The drone then started flying into a wooded swampy area while decreasing altitude. It hit the trees and fell into the swamp below. It was irretrievable. I made a claim. They asked for my entire flight log folder. After review, they determined I had a faulty Mav 3 enterprise and sent me a new one for free. I couldn't believe it. No questions asked. Sometimes DJI surprises me. I didn't need to use my care refresh either. Anyone else have any free replacements under warranty? If so, tell us your story.
