also, I find it strange that the engine sounds the same from 0% to 100% throttle. WEP will change the sound but otherwise it doesnt.
I did some landing practise of the Dover level (played thru both levels on arcade first

for the 5th time, not the last, still counting to september 4th

) and on my approach I set throttle to 0%, no change in audio untill airspeed was like 190km/t then the engine sound started dropping.
Anyone else thought about this?
