I am trying to advise a new club member about a trainer airplane. He is new to the hobby and has no knowledge about what to buy, electric, glow, or gasoline powered. I know very little about electric power and I gave up glow engine years ago. I found on the web a 80" wing span,6 lbs high wing trainer recommended power 40 to 60 glow. The firewall size looks like it could support a small gas engine. The secret to learning to fly is having a dependable airframe and engine. Is their a gasoline engine out there that is dependable. reasonably priced that will fit into this airplane?

Thanks for your help
