I don't think I have given you enough information to actually be wrong. I have intentionally been pretty vague because things will change as the design evolves. There will be some "batteries not included" kind of things that will make sense later.Please prove me and and the skeptics wrong.
I'd love to see this work out. Good luck. Please keep us updated as to your progress.I don't think I have given you enough information to actually be wrong.

I fully expect that the version you see there will have some cooling problems. I am not going to worry about it for the first prototype. To start with, I plan on just blowing 5-10 CFM of shop air through the heads and around the cylinders. Not really a great solution long term, but I am much more interested in testing out how the check valves and cylinders work right now. I am only about 50% confident at this point that the mostly off the shelf 3rd stage can handle the amount of air that I want to push through it. The entire stage only cost me $80, so I figured it was worth a try.Interesting.
Looks like there may be some cooling issues
The one off cost to me is around $200 and a bunch of time. I have built a few boosters over the last few years at a total cost to me of about $30 in seals. Material comes out of the scrap bin and I do all of the machining on my lunch breaks or after work if it is a complicated part. Obviously that plan doesn't scale well.
Cool, they let you build your own aircraft from spare parts! But, I thought choppers were more an Army & Navy thing ...This reminds me of the good ol' days when I worked as a prototype machinist for the U.S. Air Force doing R&D work. On the weekends I would come into the shop to design (CAD/CAM) and make all kinds of things from parts for my custom chopper to a full on smoker I used for BBQ competitions. All the material came from the scrap bins which is why my smoker had a very expensive yet very light fire basket.
