Thanks for your comment. I am working on the electronics for those. They need to have a smooth rpm. Most ideally they take time to smoothly start and gradually stop when fuel is cutoff. I did make a simple circuit that does something like this for the first engine. Its far from perfect yet, it's a pretty difficult problem.
A wonderful plane. Although the designers did copy a bit of work from other planes, it (unofficially - it is faster than the de Havilland Mosquito) is the fastest propeller driven plane out there.
It is as if the designers fitted every possible modern (at the time) enhancement on that plane, such as swept back wings, double propellers mounted on each engine, turbo prop engines rather than piston, etc.
If my information is also correct, I've heard in some book from my local library that it is so fast that it has gotten a reputation for the noisiest plane in military service to exist - it's propellers spin faster than sound.
Enough talking from me, you've made it brilliantly. :D
I think I have an idea to improve your DEUT factory creation. I have noticed that there are times when there isn't enough O2 to interact with BOYL and it makes BOYL get all over the place. Perhaps you could do the same thing with BOYL as you do with GLOW. That way, there would be a perfect amount of BOYL coming out to turn the O2 into fog.
