Well, if I up the sound volume on the bombers more then they are now, U will start to get distortion. I have all engine sounds at -1 db which is about the max before distortion starts. When I get more recordings for nikis's and lala's, they will be fixed too. I just noticed that the 109 supercharger sound is to loud. The eng1.wav file is the actual recording sound within the 109 cockpit. If u notice, there no supercharger whine. I think the next release I just gonna use that file. BTW, that 109 eng sound is from a actual bf109G6. That includes the startup and the shutdown. Most of the actual early 109's like the e4, f4, g2 and g6 were windup type start system. Not sure about the later 109 series though. What it was is a person or two had a crank that they turn to windup a flywheel. After the flywheel is spining at a decent RPM, the pilot wound engage it to start the motor. It actually takes about 3 mins from the start of the cranking to actual engine running for a 109.
