It SHOULD be flown as a Alt/speed junkie funky monkey.
The best thing about the yak is at high speed the lil' beast can still cut and turn with the best of them.
The shape is hard to hit,and also allows for a very clean airframe.
One thing is has trouble with tho,is the acceleration because it lacks wep.
However if you keep her over 250 for most of the fighting,you should do alright.
The real trouble comes when the yak gets low and slow "this is a no duh to almost every plane"
Simply put, the only REAL downfall is the dog crap ammo loadout. "some may say the small fule also"
If it had even a bit more cowling ammo, i would fly it more than my ki-84.
Shame.
"Edit" the yak is one of those planes that, if you make it home..you will be out of ammo, with maby a few minutes of fule left.
