This has to be the best value in all of Bückerdom. Hank Galpin has for many years distributed a booklet he wrote called "Tips and techniques for Bücker Wing Builders." The booklet is very well written and illustrated with good quality pictures. It takes you step-by-step through the process of building Bücker wings and ailerons. The booklet has recently been expanded to include a section by Joe Krybus on building the ailerons.
