Bring it on.
I prefer the "feel" of the Yaks to the LAs. Tho I dont know why you would perk the Yak-3p.
Yak-3P year-1944 engine-M-105PF2 armament-B-20M & 2 B-20S 370 20mm rounds altogether Load 0 Speed sea level-572 KMPH speed at Alt 646 at 3900 climb to 5km- 4.8 mins turn-19 seconds climb turn-1400 meters ceiling 10.05 KM range 610km weight 2708kg produced-596
LA-7 year-1945 engine M-82FN armament- 3 B-20S 450 rounds total load 2 FAB-100kg bombs speed sea level 615 KMPH speed at Alt 670kmph at 6000 climb to 5km 4.3 minutes Range 635km ceiling 10.5km turn time 10.5 seconds weight 3300
So the unperked 3 cannon LA-7 carrys more 20mm rounds, is faster both at sea level and alt, climbs better, turns better "close", carries ords while the Yak doesn't, and has more range. So why would you perk the Yak?
In fact the Yak-9U outperforms the 3P in speed and climbs/turns about the same. The only difference is, of course, the 3 cannon.
Which would earn the Yak-3P a 5 eny, or close, but certainly no perk price.
