But, on IL-2 1946, when i fly the 262 throttling up and down frequently, my engines catch on fire. So it can be that as well.
That is not modelled in Aces High, Shyguy.
The 262's engines were known to misbehave when their throttle was worked too hard but engine management is very rudimentary in AH.
Actually, Pilots were limited in how fast they could throttle up between certain RPMs in real life, otherwise they would damage the engine. That is to say, very slow below (I don't remember, but let's say) 7400rpm, but above that you can do it as fast as you want.
AH is actually quite clever. Jam the throttle full if you like, but watch the RPM dials. They move very slowly, because they are modeled to the limits that pilots had to obey in WW2. Then above whatever the cutoff point is (7400 rpm??) they start reacting almost instantly.
Basically AH models this limitation into the game.
IL2 must not, which is stupid, really. Basically lets you do something you shouldn't be able to do, and will result in engine failure very often based on historical reports.
You couldn't fly a P-51 at 200" boost, could you? Does IL2 let you do THAT too? So why should it let you rev the RPMs too fast with the same result (engine failure)?
Never mind, don't answer that. I don't care. I stopped flying IL2 a long long time ago.
Let me just say: AH has that accounted for. You won't get engine fires from throttling the engines because the position of your throttle and the position of the RPM needle are not instantly linked. It's like flaps. No matter how fast you hit the key, they still deploy at their set speed.
