John, I'm not sure where you get where I say that Subes are "best". My last reply was pretty clear in saying that there are advantages and disadvantages to both engines. My engine is better in certain categories than a Lycoming and worse in others- facts that I have published on many forums, my webs...

I should have added that my view on experimental aviation probably does not interest more than 5% of the RV community. I think most just want to enjoy flying their RVs without the tinkering I have done. What I do is certainly not for everyone and I tell most people who don't have the mechanical back...

Ross, With all due respect for your considerable prototyping and experimenting skills, I can't share your enthusiasm for this installation.

I've got over 200 hours on my IVO Magnum 3 blade on a turbo Subaru. No problems or issues. Works great. Good company to deal with. A much cheaper alternative to MT/ Hartzell for auto engines. Always lots of speculation about these props from people who have never flown one. I know a guy who does ins...
