To the tenth is definitely not used in aerospace industry all the time outside of precision fit items. Usually to the thousandth, and we have trouble getting vendors to hold it to that on a regular basis. Shafts/blades/etc are built/measured to smaller tolerances but those are definitely precision fit items. Did you put an extra zero in, or, since your name is Aerotest, do you test a small selection of very precisely machined parts? I work on APU's mostly.
It depends where youre looking, but a quick look at my APUs here show splines, blades, shafts, pump components held to 0.0001 and greater, and tight tolerances for straightness and flatness. "
It sounds crappy. There are some rolling vids with shifting too - it farts on shifts like the twin turbo V8 - like in the X6M...it farts also and that is a V8. I don't get what they are doing with their exhausts. They should be able to make it sound better.
There is that official video with it rolling through the dark past all the other gens. The vid is awesome, it looks the business. At the end it revs it's motor and I literally LOLed the first time I heard it.
