Radius fight vs. an F-18? Not a great gameplan.
Now, the Mig cannot win against the old F-15. Even a young inexperienced pilot can easily beat a Mig-29 in an Eagle. Mainly because of the massive power and superior thrust to weight ratio. Add to that, the incredible maneuverability and agile slow flight characteristics of the F-15.
My nephew (Who now flies an F-22) went against the Navy's best Top-Gun program instructors, them in F-18’s and him in an F-15E. He beat them hands down. After defeating them one on one, they ganged up on him 2 to 1 and he beat them again. He said it was easy. All he had to do was force them to push the limits of their limited flight and climb performance as well as several proven tricks he had learned during actual combat dog fights. (Desert Storm)
What he can do in the Raptor is classified but surely well suited for a pilot like Lt Col. P’.
