100% Operator error. Short thread here just to ask if anyone has experienced this and how you handled. 2.5M in altitude on a normal landing approach.....sudden wind gusts of 28 km/hour drove her backwards into a low hanging tree branch. Hit branch, flip and drop straight to the concrete. Landed 180 degrees upside down. All 4 propellers hit the concrete at the same time. Immediately hit shut-off of the engines but no response. Bird continued to try to fly itself down into the pavement at full speed for roughly 8 seconds before I could reach it. Picked it up, shut down the engines....... 4 Propellor heads were worn down like I had used a sanding device to smooth them down. Shaved off at least 5mm of the 4 DJI carbon-fiber prop heads. Did a full laptop assessment, changed props, re-tightened hex screws beneath props, new flight, no problem thank goodness...... Should I consider other testing or repair? Thanks guys.
