I somewhat reluctantly offer the parts I have completed to build a Hummel Ultracruiser, but I realize I'll probably never finish it. I have all bulkheads made and the MDF form blocks are included. All stick-built rib parts are cut. Misc small brackets and tail ribs are built/formed. 6 - 4'X 4' sheets of .016" 6061-T6 aluminum. Serial Numbered plans will be included and would contact Hummel to re-assign the Serial Number. Firm at $600.00 Contact Lynn (573) 788-2574 email@example.com I can take photos but a phone call would be a great place to start.
