Wow Jim that is a serious set of engines, I have a hydro that I run once and a while, nothing serious but by far the most fun to run out of all my r/c vehicles. May I ask where you are from?
Your research and development work is extremely impressive! I'm definitely looking forward to seeing everything that you share with us! Your engine test stand looks like a useful fixture. Do you use it to run engines in or to get power measurements? Is propeller speed your primary method of determining an engine's performance or do you have a different method?
1 HP is approximately 4700 watts of heat.

Still, 7HP (5.2kW) is roughly 20% more heat than a typical gas stove top burner on max heat. Have you run any of the Nelson engines on the dyno?Jim, great stuff as usual. I've been reading about your work since 2008 or before.Greg
Please let us see a picture of crankshaft ,bearing and Coupling.What is mass of piston plus pin?.The reason that You do not need needles in the upper conrod eye is that at 30000plus rpm piston is lifting against combustion pressure so that oil can come under pin.For normal speed two stroke this is not the case .
Thanks for that. I was curious how much power Q40 engines were making. I saw mention of 4+HP and didn't realize they were making that much these days.Greg
