Soviet fighters and 4.12

[JtD]

It's possible to fly fuel tanks dry on 110% with rads open in a 109 K-4, and that not only on winter maps. I just climbed one from 0 to 10 km at 300 km/h IAS on the Smolensk map. I left it on auto rads and firewalled it upon starting the engine. I didn't even see the overheat message, let alone had temperature related troubles.

Also, just because it overheats it doesn't mean there's any damage. In real live WEP was an 80% overload condition, and it is only logical that the plane overheats in game to illustrate this.
