RE: Theoretical question
From what I have seen, you can't compare DF thrust to turbine thrust. I have seen a BVM F-86 fly with the little GWM 7 pound thrust turbine and it flew every bit as good as one with a Viojett fan with a BVM.91.
If that F-22 will fly on 2 Dynamax fans with K&B .82s, then it would probably fly with 2 MW 44s, but it would not performvery well. For vertical performance similar to the real one, you would need more thrust than the RTF weight of the airframe.
