In my opinion, I see to major issues:
1:The "curve" seems to be off - I can takeoff and climb at 500kts, but I can't reach FL450, even though it's in the B-52's range with no extra weight and 50% fuel.
2:The infamous "no pitch takeoff" is impossible. i assume some of that is because of the lack of weapons, affecting the handling. Any change would be apprecaited! I'm wating for V1.1 to reprint my manual so it will reflect all the changes!
