Just wanted to add, the F210 seems virtually indestructible, I took my eyes off it for second or two ( was interrupted by a spectator ) and slammed it into a telephone pole at full speed, then it spun around and slammed into a brick wall of a restroom building. Thought for sure it was toast, picked it up brushed it off and it flew perfectly afterwards.
The most vulnerable spot are the 2 antennas protruding from the frame, easily replaced and cheap.
I highly recommend this pocket rocket for entry level racing drone enthusiasts.
Check it out.
