The Yak9T.
Pros:* Good visibility all the way around, probably as good as P-51D and P-47 bubbletop.
* 1 shot, 1 kill capability via the awesome 37mm nose cannon.
* nose-mounted cannon means no convergence worries.
* fast enough to engage the other late-war planes, such as the Mustang, 109Gs, 190D, Corsair, etc., so long as you use the 12.7mm machine gun to ping them up a bit and scare them into turning.
* compression is not an issue, unlike the 109G series and P-38 Lightning.
* durable and turns fairly well, particularly down low.
* unlike the Yak9U, the 9T has WEP.
* cannon has better ballistics than the 30mm mounted in the 109.
* could probably put a hurting on ground armour if I could avoid nose-planting long enough to see the results of my handywork.
Cons:*Don't leave the airfield perimeter with less than 50% fuel, particularly on the bigger maps like AKDesert where the airbases are spread far apart.
* slow rate of fire in the nose cannon, and only 32 rounds of the 37mm shells, so fire it like a sniper rifle - 1 shot is all you need and it'll be awhile before the 2nd shell reloads, so make that shot count.
* 12.7mm machine gun is good for strafing gun emplacements, making the wild-guess snapshot where you just want to wound the enemy plane as best you can, and for pinging a running plane at long distance.
Advice:* Don't fire the cannon and the machine gun at the same time. You'll never know if you're hitting with which gun. Use the cannon for the kill shot and the machine gun for general-purpose shooting.
* Use tracers. I normally don't use tracers, but for this plane I think the tracers have the advantage of allowing you to scare the other plane into turning if you fire a few rounds of 12.7mm past his canopy. Tracers will also let you figure out the rate of fire of the cannon.
* The cannon has good muzzle velocity and seems to keep its trajectory pretty well, certainly better than the 30mm in the 109. Still, you don't get many shells so make sure you have a shot before you squeeze that trigger. This means get in close if you're a bad marksman like me.
