Again, I just find it a really interesting part of the game, a plane that was given SO much attention and praise, that has fallen from common use, unlike the first week or so it was around. I wish Lusche could chart it's use that first week or two, and compare it say to the last couple weeks.
I do not know in which arena you fly in and at what time, but I see a lot of Yak3s. People stopped complaining about them in the forums because it is pointless to continue to do so without documentations - and so few of those exist, especially in a language that does not include some extra funky-looking letters and letters that are used wrong...

The other reason for the lack of complaints is that like the LA7, there are very few good sticks that fly them. The vast majority of Yak3s that I meet are not flown very well, which is fortunate for the rest of us.
Yaks seem to be where the "bug" in tators comes from...
Definitely have more yaks take a tator and get only oil leak then any other fighter in game.
I hit a Yak-T with a 37mm AA yesterday and he got an oil leak from it 
The Yaks have a funky damage modeling, especially the Yak3. Most players think it is due to their small size and the way damage is assigned to specific parts by the game. I had Yaks survive a full volley of 4 hispanos from nose to tail and come out with a fuel leak. There are some flukes like that with any plane due to some randomization I guess, but it is much more common in the Yak3s.
