My pleasure, Pakrat sir.
Unfortunately the old flightmodels of Warbirds were/are not very historically accurate when it comes to handling and stall speeds etc. The Yak-3 historically not only had small wings, but also quite thin wings with a Clark YH profile of only 14% thickness ratio at the wing root. What this means is that it's wings cannot sustain a high angle of attack when pulling G's, and the plane more easily high speed stalls. A positive effect is that it is quite fast for it's low horsepowers due to lower drag, and the Yak was good at countering the German Fw 190 as it could easily turn inside a Fw 190A-8 and roll with it while almost matching it's top speed at low altitude.
The Yaks were documented to have quite a snappy stall behaviour with the wing dropping quickly at stall, which is what we've tried to model. Their predecessor the MiG-1 was extremely hard to fly with pilots stalling out and spinning to the ground even when intercepting German bombers. The Russian engineers fixed most flaws with the development of the MiG-3 which also was given automatic slats. The Yaks didn't have slats though in order to save money and production time, but their wings were a bit redesigned and more stable, although a Yak pilot still needs to know his aircraft in order to be able to fully ride on the edge of stall. I will fly the Yaks this week and check so that this snappy stall behaviour is not harsher than intended. It's always good to re-check things

Bollok has been learning how to bring new flightmodels into the game, so tbh it should be quite possible to put the Yak-9U, with the VK-107A engine, in Warbirds if Ient approves. This version had a much stronger engine so should be both faster and hold a sustained turn better than both current Yak versions in Warbirds. Would be nice as this would allow the Yakovlevs to stay competitive even in the late war RPS era. I will look into it this coming week, sir.
