2 times, first time I had just "found" sport mode, full throttle into the eve of my roof, tore up 2 props, knocked gimbal mount out of place, my heart stopped... fixed gimbal mount added new props was flying in half an hour. Second time, at Knapps Castle near Santa Barbara, Doing a side slide, didn't see the tree. Stuck 50 feet up. Drove down the hill into Goleta home depot, bought 60' 1/2" EMT conduit, pipe cutter, duct tape, pond net, screw driver and conduit connectors... back up the hill, tape net to conduit, start adding more conduit... 5 hours later, Mavic comes down from tree, gather my stuff, go home, PRAY, fresh battery, 4 new props and flies like a champ. I am so thankful this thing is as tough as it is!!!!
