There are some tests made for pure curiosity, and this is one of them. I've flown this thing a few times and thought it was pretty underrated, a gem in the muck. Now, the LaGG-3 was considered a bad plane because of it's wood construction, bad handling, and shoddy inconsistent quality.. Since this is a game, all quality is all the same, the instructor negates most of the bad handling, and wood construction is more widely considered a gift from Stalin himself, leaving an okay plane. Level speed is great and firepower is amazing, but the climb rate is quite bad and the redline fairly low. Vertical dives are particularly dangerous as the plane is very heavy and accelerates very well in a dive, so you can hit the red quite quickly and won't be able to pull out until it's too late.
There's also a strange problem with turning when below 300m, the plane goes wild and the instructor goes nuts trying to correct it. Really screws the turn time.
