Wooden fuselages

I have posted several design ideas for wooden fuselages to fit Jack Womack's Houston Hawk, Yardbird, and Bantam wings and tails. These fuselages are not official parts for the Houston Hawk, Yardbird, or Bantam and planes built with them need to be understood to be modifications and not true planes bearing Jack Womack's design names. They are just drawn up as options that can work as wooden versions for those wings and tail sets.

Here they all are. The revision date is listed on each plan. I have not built and tested some of these yet (I hope to soon) and I am not an engineer, just a modeler, so these are use at own risk drawings. There are photos at the bottom of the ones I have built.

Before printing be careful that the printer results with 100% scale at the bottom right of each drawing to confirm that you get 1:1 (1 inch on drawing equals one inch on printed page).

** My suggestion is that before printing, have the person doing the printing double check that the scale will be correct for their file+printer. Sometimes printers shrink or expand the drawing when printing. I have received a report of the Yardbird fuselage pdf printing at a result that was 68% of full scale. This may have been because I had too much on one page for the drawings so I have split the large drawings into two sheets, one that is the plan and the other that shows the profile and dimensions.

If reduction persists with these new files, I believe that you might be able to avoid that by setting the print percentage to the inverse of the resulting reduction (132% to compensate for a 68% reduction) or print directly from the dwg files with no reduction applied when printing, but that will require use of a CAD program at the printer. **

Fuselage for Yardbird wing (see photos at the bottom):

Updated: 10-20-12 -- Added a more accurate rendition of the airfoil which makes the top of the wing saddle area very slightly curved to match the bottom of the wing.

Updated: 12-22-12 -- Changes and modifications resulting from build of prototype fuselage.

Adapter to fit Houston Hawk wings to Yardbird or similar top-mount fuselage (see photos at the bottom):

Updated: 10-21-12 -- Added a plot of the airfoil and a more accurate rendition of the airfoil which will fit with to the Yardbird's wing saddle area which is very slightly curved to match the bottom of the wing. Matched the HH root rib for the joiner rod and incidence pin.

Updated: 11-24-12 -- Redesigned reinforcement around joiner cavity.
