Another good point. I think it was said a long time ago that the Il-300 uses cylinders that are much too long when compared to the actual stroke of the pistons. I seem to recall that the explanation was about having a more scale like engine for certain applications (perhaps WWI inline engines?). The downside is that this makes the engine unnecessarily tall, making it harder to cowl than it should be.
I wish OS would make a "short cylinder" version of this engine with, say, 1 to 1.5cm shorter cylinders. Same everything else. It would be so much easier to cowl...
