2nd day buying a used bebop 2. Looks as if one of the propellers broke about 20ft in the air. Landed on its top. The gps board up too is bent, and obviously the missing propeller. Also one of the gps antenna on the bottom feet came off I ordered a new gps board and new antennas. I noticed the motors seem to have almost a lean to them. All of them when spinning by hand. Like goes a bit up and down. Is this normal. Also anything else I should look out for after a crash. And the battery is shot. Have to order a new one.
