Now the wing pieces probably have more curve than they need. Grab
one of the parts with the airfoil shape, (Like the struts, or the landing
gear mounts, although the fuselage will do too.) and use it to check your
airfoil. If it’s not an exact fit, massage the wing a little until it’s pretty
close. The glue will do the rest.
(Note: If you have the FoamFly.com Wing Jig, you can bake wings for
this plane using the same standard airfoil. The Staggerwing uses a
subsection of the Frog Airfoil. You would cut 1” off the leading edge of a
baked panel, and 1.5” off the trailing edge to make your 4.5” chord
wings.)
d) Use the foam Dihedral Jig to sand the required 5˚ dihedral into each
wing. Clip the tool onto the tip of the wing that you’re working on, and
then cut or sand the root of the wing exactly vertical. You can do this
easily by holding you sanding block against the edge of your kitchen
counter, and then pressing the wing end against it. (I would recommend
that you slide the wing back and forth, and not the sanding block. It’ll
help protect your counters, and maybe your marriage.) Be sure to keep
the wing in it’s finished airfoil shape while you’re sanding. If you like,
you can slip on of the foam landing gear mounts under the wing about
2” from the root, and press down on it to hold the airfoil shape while
sanding.
e) Glue the wing halves together. If you’re using contact cement, you can
just wait until the glue is dry but still tacky (about 10 minutes) and then
press the wings halve firmly together. If you’re using Epoxy, or another
slower setting glue, leave the Dihedral Jigs clipped on the wingtips to
hold the wings at the correct angle while the glue dries.
f)
Identify the Wing Struts (The kit parts are marked with a small ‘L’ and ‘R’
for the Left and Right Struts. They have a 5˚ angle cut into them so
they’ll sit flat on the wings after the dihedral has been sanded in.)
