Joe,
Your timing is perfect! I was looking for a nice VN diagram last night to use as an example. This one has all the complexity to show what is needed for a WW-I design and a few things that aren't (so we can explain why).
As a starting point, every design has a different VN diagram! DON'T try to use this one for your Eindeker!

OK, I really didn't think anyone would think they could take an Eindeker to over 200 mph, but you never know!
