Unless I'm looking in the wrong places, it seems that websites selling plans don't do a great job at describing specifications/purposes/etc. for planes. I guess they assume that if you are smart enough to build your own, you can figure the rest out.

I'm looking for plans for a flat-bottomed, high wing trainer (preferably a Basic Trainer). The only Basic Trainer I can find is from RCM. It is a bit smaller than I want (it being 53" wingspan at approx 470 square inches) and was drawn up in 1968--I'm assuming some building techniques have changed since then. I was wondering what another good flat bottomed wing trainer plans exist out there that would take a ".40ish" engine.

Thanks.
