I do beleave the Typhoon should be perked, 400mph top speed, bubble cockpit and 4x hispanios, that thing is a terror! I fly it all the time to challange people in temps (H2H), and if used right it's awesome, just keep your speed up.
The Ta-152, I understand why it's perked, best performance at 30K and one of the only planes that fighters well above that, awesome firepower and very good range. I can use it well around 15k, but forget it if your below that.
The La7 I do beleave should be perked, aswell as the 109G10, but that seems to be being replaced by the K4.
I also agree the that the P-47N should be perked, same reason that the Ta is. You can have something almost as good as a Ta at alt thats even better at low alt, it's a monster!
Also for the Spit 5, I heard that the FM is being toned down a wee bit, so perking won't be needed.
AND REMODEL THE N1K!!!! lol (I love that plane, but god is the model ugly)
