The yak9u is an incredible plane. If anything, it's ENY value needs to be lowered. Under 8k it's a nightmare. It can turn better than an la7, it can zoom climb as well as a G10, out-accelerates a G10, and outguns it. Basically, the 9U is the low-alt E-fighter's dream. The 9T on the other hand is garbage...
And Chris, you left out the 109F. I'm considering switching from G10's to F's, despite the obvious disadvantage I'll be giving myself

It's ENY value is too low.
The LA7 and Mustang should have an ENY value of 10... I personally don't think the Spit14 should be perked, since it's just a spit-shaped mustang. The dora should be perked, and the 152 de-perked. I think the Typhoon's ENY value is a bit too high (22 or 24, I believe?).. it should be in the neighbourhood of 15. The thing is the ultimate fighter in AH.
Give us the later-war stuka with 20mm and I'll gladly attack bases (I know it's unrelated, but hey

)
