You should be able to hover ok.

You're mixtures will probably be a bit leaner at that altitude.

The os 32 is a decent engine and the hawks are pretty darn light.

Hawk sports are OK but WATCH the tail when you build it. If you don't jb weld the lock ring you will lose the tail in flight and crash.

Personally, I think having to JB weld anything is pretty poor engineering, also if you ever want to take the tail down to lube it you gotta pry the JB weld off.

For the $159.00 though its a deal. The stock links though are pretty tough to get smooth and the head is not very smooth.
(I'm comparing this to my Freya though so its really not too fair)

However, as soon as you're over the hovering stage the limitations start to show, like slop in the linkages, lack of bearings in critical places etc.

DOn't get me wrong though, a pretty good heli to ring out and try everything with no fear of crashing.

Just my 2 bits...
