Branden,
An Idea. I helped a friend add some authority to his - still in phase - I Avid Mk 4 by extending his elevator. He brought full size drawings obviously copied from an elevator that was laid over the paper. It was fairly straightforward and easy to do. I particularly liked the means of attaching the trim tab - so much easier than the cut out tab on the Kitfox. I have done several of the Kitfox style trim tabs as well - but without extending the elevator.
