There are several notes I need to provide to aid you with the enclosed package. The original
kits used 1/16" balsa. Since I wanted to print these directly on balsa sheet I developed the
parts for 1/32" balsa sheet. My printer will handle up to 1/20" sheet, but I find 1/32" is a little
easier to handle in the printer. As a result, some of the parts have been drawn to allow for
cross grain laminations. The fuselage formers are a good example. The fin as also been drawn
with a mirror image to allow for markings on both sides. This works fine as long as you are
using 1/32" sheet stock.
I like to use a removable nose for winding. The Zero parts have been drawn with this in mind.
The nose former has been drawn so a removable nose plug can be used. Colored parts have
been included on the parts sheets to allow the build up of a removable nose plug. The plug will
fit into the square opening that has been drawn in formers 3 and 4. Use enough disks so the
prop will clear the cowl. This assembly will fit through the opening in the cowl. I like to use a
Peck thrust bearing for 1/32" prop shafts in the removable nose plug. A drawing of this
removable nose plug has been provided for your reference.
When using 1/32" sheet for the fuselage sides, I was concerned about the load of a fully
wound motor on the rear motor peg. I like to use a piece of 3/32" aluminum tubing for the rear
peg. Makes holding the model in a winding stooge very easy. To create a bit more strength at
the rear peg, I apply a 3/8" diameter disk of 1/64” plywood to the inside of each fuselage side
at the peg location. This has proven to be plenty strong for a fully wound motor of 1/8" Tan II
rubber. A piece of 3/32” OD aluminum tubing is used for the rear motor peg.
The landing gear parts for the Zero have been drawn per the original kit. Mirrored parts have
also been drawn to allow sandwiching the landing gear legs between the 1/32” balsa parts.
This makes a nicer looking installation and is quite strong. The location of the gear legs has
been printed on each wing panel. You will see a line with a circle on one end. Push the landing
gear wire through the printed circle. The bent wire will line up with the printed line.
The original kits came with a vacuum formed canopy and cowl. A drawing has been provided
that will allow you to develop forms for making your own vacuum formed parts. The original kit
cowl came in red plastic.
I do hope you build and enjoy a model from this plan package.
