pretty interesting discussion this turned into . But i never had any of these "mig vs f15" thoughts when i started it.
I just noticed, that i couldn't stay up in air @ 40.000 feet without afterburners in the mig. It will just gradually lose speed and start falling.
If i remember, with LOMAC you couldn't do that in F15 either . Now however, you can quite easily stay up there without burners, and reach pretty good speeds as well (350 knots, just cruising @ 43000 feet, 1 outer tank, and 8 amraam's and full inner tanks).
You can't move or anything cause you'll spin right out of control but i guess that's work in progress.
I just thought that maybe i was doing something wrong when flying the mig.
I am not sure how the mig performs in real life, but since the power to weight ratio is high (?) and since it's a very manouverable aircraft (big wings) it SHOULD be able to do it.
