My year old Air spun into the ground from 350 ft. Never has it done anything like it before. needs arm and camera. Should i fix or write it off. Will it do it agian?

I have replaced both front arms with motors on a Mini and it was not very hard. It looks like there are arms for the Air available for $30. I don't know about a camera.

I found an ebay camera for $30,  and it need both rear arms/ motors. just dont know what caused it, or if i should repair

Your .txt log file may have a clue. Post it here (in zip file) or to airdata.com and we can take a look. Possible bird strike or propeller breakage?

Sorry to hear about your crash.  Might be time to upgrade to Air 2 or Air 2S.
