Thanks all. By the way, my school is in the process of building a Sopwith Pup. They are just getting started on it and I'm looking at volunteering time on it. If I can, I'll start a thread that will cover the build of this plane from wood to fabric to engine to flight. The school also just received a sea plane for the students to work on... It's still in pieces so this means we get to build it back up.
