Default YS 45 for a scale subject?

I am considering this engine for a scale WWII fighter model with 800 sq.in. of wing area and will weight about 7.5-9 pounds loaded with fuel.

Will the .45 be stong enough? I'm not looking for unlimited verticle, just typical WWII manuverabilty with some HP to spare in emergencies.

The .45 interests me because of is reputation as a "hot 45", its pumped fuel system (I want to put the tank on the CG) and rear exhaust (I want to use a tuned pipe running through the fuse).

Thanks for any insight or comparisions your can provide

A 45 of any type will not be enough for this airplane. Maybe if you just wanted to cruise around the sky it would be ok, but if a situation ever arises where you need some extra HP, you will be in trouble. Go for a YS 91.

Thanks Dave for your quick response and insight. I think the 91 would more than do the trick, however, I was looking for a two stoke solution. Its too bad YS does not make a big brother to the .45, say about 75 -90. I know of the YS helicopter engines, but I am unsure of their application inside airplanes - any thoughts.

Thanks
ScaleME

PS. The model is a scratch built ME-163, 73"WS
