She's a screamer! I'm still running 3S and just started moving from Horizon to acro today. 2 of my 4 birds will need to go on to the bench for repairs!
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.
