AKAK is correct, as a fighter vs fighter in the LW the Yak-9T is mediocre at best, over 10k alt it's very mediocre.
As for killing GV's that's never been my interest I simply can't see the reason for wasting good ammo on a tank and there are plenty of better aircraft for gv killing if that's your thing. I rarely even bother with buffs.
What I can comment on is the planes performance/abilities vs cons in the LW most of which are the usual late war uber rides.
Basically the Yak-9T unlike the Yak-9U which usually has parity or some performance advantage over any other ride which makes it quite deadly. The Yak-9T has little or no performance advantage. Cons are either faster with much higher performance and climb rates and those that are equal speed or slower turn harder and maintain E much better.
Also someone mentioned fuel range, that's true it is very short by the time you reach 10k if you were to bother you'd already used up 1/4 or a tank at full power, hence most flights only climb to the 7k range. To extend the range you can reduce MAP to 31" but then your traveling a little over 250mph and acceleration to 300mph is slow unless you want to sacrifice alt.
Having said all this, I think the Yak-9T is fantastic and the most enjoyable (for me) ride of the entire planeset probably why I've stuck with it as sole ride for couple years now.
It sucks at base defence or large furballs, simply because the uber rides with hispanos are going to get all the kills much faster then you. Unless your having a very good day with gunnery and able to nail a few first pass. Often though you need time to saddle up and look for snap shots in Scissors. Plus furballs over or around bases friendly or enemy aren't my cup of tea anyway.
Basically the Yak makes for a great lone wolf interceptor style of play which I enjoy.. And to sucker people in for extremely close up ACM and snap shots. Yak-9T is good at this for the obvious reason, the massive 37mm single shot KO on almost anything. Though the 37mm can be the most frustrating and difficult thing to hit another fighter with. But at times when you have the timing right and can nail most shots it is extremely rewarding to get right.
I've never seen the Yak-9T as a long range sniper, simply that wastes ammo and I think a lot of the stories on this BBS about kills at 1.5k on an extending Pony are pure BS. Simply because if you load a target in TA and fire a round the group at over 1000 isn't very tight compared to the size of an aircraft at this range, so to hit at 1k or over you either have to be extremely lucky or empty half the ammo load which isn't smart with only 32rnds to start with.
Anyway I could yap on for a while in the Yak-9Ts fun against other fighters, and really that's why I fly the plane, because it's the most fun and challenging for me and that it gives others something different and interesting to come up against then the usual lineup of LW uber rides.
If anyone wishes to discuss the Yak, please message me as I don't frequent the BBS much anymore.
MBailey thank you sir, and for your comments. Always a pleasure and that fight was one of the best, great fun!
