RE: Welcome to Club SAITO !
Hey Dave,
Your right, sorry. I run 15% coolpower and a 15x8 APC. The engine is tuned 200-300 rpm below peak. It's strong and will hover the CG ultimate. A few years ago I ran the engine in a Sportsman Aviation P-47. I thought it would be faster than it was. I tried different props on both but never saw much better performance. I also keep the tapets adjusted.
