Hi rcwarbirdbuilder,
Looks like it ought to be a nice fun flyer. My only suggestion is to make really sure you water proof the spar and spar socket area. If water gets into any bare wood it will swell and cause all kinds of interesting things to happen. It will definitely expand your vocabulary of colorful metaphors!
Good luck with the build and keep good notes. You may have a line of people wanting plans for your Great Drake.
