FHHUBER,
I can't disagree with you totally. Under normal circumstances I would agree that a 10-7 2-blade is a pretty good load for a .46.

However, in looking over the Irvine specs, I found that the lightest prop that this engine wants to see is a 10-8. And, it lists heavier props in the 11" and 12" range. The Irvine spec sheet doesn't even list a 10-6 or 10-7 prop.

So, I decided to try the 3-blade prop. I think I was mainly looking for an excuse to see what a 3-blade prop would be like in a plane. If it doesn't work, I have a 10-8 and an 11-7 for the Irvine. I also expect the torque to be different for a 3-blade prop.

Has anyone else tried this combo???? I'd be curious in your feedback, though we are getting far away from the original question here...
