The plan was for a giant delta(a scaled up Diamond Dust to 60"), but I cant find the time in this lifetime to get to it, so there it sits. Maybe if I won the lotto and didn't have to work. [sm=teeth_smile.gif]

The engine was in a Sundowner 80" and plane type dedicated (tight fit) Pitts muffler using the same prop. It was turning 7800, new engine + restrictive exhaust. I liked the 17X12 better, don't remember what that turned.

Sold the plane, kept the engine.
