Initially I was using an OS 46AX to power my Long-EZ. It was quite adequate but once I installed the cowling with plenty of openings it tended to run lean. Now part of that problem was more than likely the defective "quick fueler" I installed on the side of the plane. So I changed out the "quick fueler" and since I have always liked Supertigre engines, I figured the Supertigre GS45 ABC with its very tall thin cylinder head fins just might cool a little better.

About $69 spent at the LHS for the Supertigre and things are much much better. This engine makes a LOT of power even set slightly rich--enough to leave a very noticable smoke trail in flight--running on 10% Wildcat fuel. It is also very fast, I generally fly at about 50% power and that is plenty fast. I've probably got it under-propped as it makes a very unique sound in the air. The stock muffler being the rotatable "barrel" shaped thing I've got turned 90 degrees to the fuselage.....so it looks kind of like a volkswagen (or better yet a Porsche 911 "sausage" ) muffler. Idling on the ground is no problem. Even with the cowling installed it will tick over at an extremely low idle without getting hot. So no worries about "get it flying quick in order to cool the engine!"

I'll take a look at what prop I'm running and report back. Maybe even a picture.
