Nice addition to the ISO cellar, Kugerfang, really a nice one.
For those who try it out and likes it, a tip:
You should also give Falcon 3.0 a try, even if SU-27 is a nice game, Falcon 3.0 beats it completely regarding gameplay and graphics.
Or even better Falcon Gold (that's Falcon 3.0 plus additional campaigns and extra planes you can fly).
.... just saying .....
