RE: PAK-FA: video
Was the F-117 really setup as a dynamically unstable aircraft? I thought they went away from that and back to relaxed stability when the F-16 didn't work out so well initially.
Interestingly, the F-22 seems to have gone back to full dynamic instability. Pretty amazing to watch the elevators deflect to set a pitch rate and then immediately return to neutral, then deflect in the opposite direction to stop the rate upon command of the pilot.
