Much as I'd like to see the "USAAF Uber Flaps" toned down, I have to ask:
What if they're talking full flaps or takeoff flaps? 1 Notch is a small amount. Perhaps the 198MPH is meant to prevent destruction from a higher angle of deployment?
If you can find more info please send it to HTC! I'd like to see P41 and P47 and P38 flaps efficiency reduced.
