I am really new at this -- but this is the beginners forum...

If you want to use a 60 engine why not consider the Four Star 60? I am building it as my first kit and putting a OS 61fx in it. It seams like the obvious choice??

Not being critical I am just curiuous of why put 60 engine on a 40 airframe when the same airplane is available in a sixty size.

Standard fuel tank is a 12oz but some people are uping that to 14/16 oz. Certainly would give you longer flight times.
