2. Using a sharp exacto blade, cut a slit through the wing in the center of the spar slot
12.5” long from the center on each side. Apply a little white glue or epoxy to both
sides of the 1/32” plywood vertical spar. Insert the vertical spar so that it goes
completely through the wing without extending beyond the surface of the wing on
either the top or the bottom.
3. Install the spar strips. Measure and cut two lengths of 1/2" plastic strapping so that
they are the length of the wing. Sand the strapping to help the glue adhere.
This is very important. Lay a strip down on a sheet of wax paper and apply epoxy
to the strapping, ensuring that there is an even layer of epoxy with no dry areas.
Lay the strapping in the notch on the wing and apply a length of wing tape or
packing tape over the strapping to hold it in place. Install the second spar in the
same manner. Give the epoxy a chance to set up before moving on to the next step.
4. If you prefer, you may shape the wingtips. I like to cut a radius into the front of the
wingtip to give the wing a more sweeping look. This is also a good idea if you expect
to be crashing as it makes the wingtip stronger. Cut the radius with an xacto then
sand the cut even and rounded.
