RE: .30 or smaller 4 stroke engine?
I must confess that I get very little sense of pride from just slapping together a kit just so I can have a model to fly. Gluing balsa is nothing special. Now on the other hand, if I really want to pour my heart and soul into a model, I'm going to be doing more than just "put a kit together." But, honestly, I'd rather have a nice looking ARF than a self-built 4*40.
