I've had my bird since august, and have flown it about 75 times i would say........only had 2 close calls, and both were my fault.......first day i had the drone, i clipped at tree branch that sent her tumbling, luckily she fell back into a hover and i was able to bring her home safe.....second time i was flying over water and wanted to fly backwards to capture the shoreline, and instead of pulling down on the right stick, i pulled down on the left stick, and almost put her down into the lake! so 2 incidents (both my fault) out of 75 flights, i'd say thats a pretty good statistic towards how great these birds fly.
