I thought the flameout was caused by sudden advance/retreat of throttle levers.
I think our 262 reacts with a 'safety buffer' regarding throttle control, so no matter how fast a pilot fiddles his throttle, the RPM rate of the jet engines change at a certain, slower rate. Something ofcourse, which the real planes did not have, but just implemented in AH.
On the other hand, one thing that would be really interesting is if HTC implemented engine detonation or CSU malfunctions due to sudden throttle inputs in prop fighters. I don't think such a feature would ever be implemented in AH, but it does give something interesting to think about.
IIRC, not many fighter pilots fiddled around their throttle settings as we do in the game. They'd just set the throttle to predesignated positions, and duke it out. I think only the best of the pilots would ever fiddle with the throttle during combat - at least, at the rate we do in the game.
