Waffen,

I can tell you right now, YES!
UP has altered some stock flight models, damage models and weapons models.

Specifically tested by myself are the heavy bombers. Their engine performance has been lowered drastically while FW 190's have been improved.

N.B. i have it on good authority that UP has also altered some of the fm's from hsfx buttons file, which is one of the reasons that the two are not compatible with crt
P.s, UP also say that hsfx buttons is an arcade buttons file (which i dont believe for one minuet)
