Pre-flight anticipation is for the plane to feel not as fast as a mustang (but similar), and not as nimble as a spit but maybe a 109 (like a bloated early-mid model 109 with less rudder/tail authority). If the books are right, it should have the potential in speed and maneuverability to hold its own in AH, but still won't be the most user/pilot friendly fighter in the game (small/squat cockpit, and I've read a couple sources and heard from a couple pilots that it's tail/rudder surfaces (or rather, lack there of) is the plane's real problem, often times resulting in departures from controlled flight if you were careless and/or heavy with the yak's ailerons.
It's not a 152, and due to not having a similar CG I don't think it will have similar problems with tail-first slides from 28k to terra firma, but (books, manuals, and pilots have indicated) it should have a similar departure from controlled flight at high speeds along the yaw axis if one gets too heavy/agressive with the ailerons in a roll/break. I will be looking for this in AH tonight while flying the plane.
The one thing I don't know to believe the documentation on though, is that supposedly this described manuever doesn't wipe all your speed
and you recover (maybe the plane recovers itself) rather quickly after inducing the uncontrolled departure,
and in the original forward direction. (You're going 350 knts, slam the stick over, tumble with your arse infront of your prop a couple times in the air, and miraculopusly will recover heading in the same general direction and just a bit slower than before....

.... sounds way too Hollywood/unreal to be true!)
