Did you hear any noises from the engine?

Same thing happened to me and I heard sputtering(coughing) noises from my engine and I immediately assumed I took some dirct hits.

not sure yet, but your engine can suddenly stop in Sim.

If you run WEP too long your engine will overheat.

I've seen that happen in Arcade i tested it in SIM flying with WEP for long time nothing, but stil often my Engine suddenly stops or i lose airspeed. Still dont know what is causing this.

:-P Vapor lock?:rolleyes:

What's that?

I believe that its where the fule turns to vapour and travels to the carburettor stopping fuel flow to the engine. Sort of like having a bubble in your blood. Correct me if im wrong!

and why would this suddenly be happening?
There is just so much i dont understand :P
Like cant seem to Trim, my plane also always wants to roll to either sides.
Or the engine stops or i just lose random power.

Well how high were you? its probably the altitude as the fuel would have a lower boiling point. The rolling is possible induced by the torque of the engines. Does it occur when throttling up and down?

Last time i lost power i was just flying average height i always fly in Tiger Hunt, About 1000 meters, height u start in.
The rolling is just sometimes there, but doesent have to, just tested with different speeds stayed the same. Maybe a trimming issiue?
