Yak3 was a totally different bird in Warbirds compared with AH.
In Warbirds it was a very fast fighter, one of the fastest in the plane-set, but lacked the turn at high speed, and exceptional ability to zoom up like a homesick angel like it does in AH.
Turning hard in the yak3 at speed in Warbirds felt close to how a 190 turns, very high AOA resulted in snapstalling it, in here it really is a non-perked uber-bird together with the bruteforce La-7.
If people in the area worked together as wingmen in a yak3- la7 combo they should be very hard to beat, fortunately for me cooperation almost always come only with numbers.
