Optional Assembly Procedures:
The following are optional assembly steps/processes that are referred to through-
out the assembly manual. Whether or not one performs these steps is completely up to
the builder and how the builder might feel these procedures will enhance the strength or
performance of the airplane.
OAP-1: “WPFG-1” Wing Panel, Fiberglassing:
Prepare to Fiberglass:
After removal of the OraCover© material from the wing
bottom, as described in step 4, apply two strips of masking
tape at least 3/16” inside of the OraCover edge. Wrap the
masking tape around the leading and trailing edges. Apply
masking tape along the trailing edge at the intersection of the
trailing edge and the wing bottom. Repeat for the leading edge.
Cut a piece of fiberglass (1/2 to 2 oz.) to fit about 3/16” to
1/4” inside the masking and from the leading to trailing edge.
Apply Fiber glass:
Mix fiberglass resin (polyester or thinned-epoxy), apply
to the fiberglass cloth and squeegee out as shown. Squeegee
it thoroughly into the fiberglass cloth and do not let it built up
too much. Allow to flow and drip off the leading and trailing
edges .... the masking tape will prevent the resin from flowing
under the wing. Allow to cure.
Finish:
Remove the tape and trim (flush) any cured fiberglass
from the leading and trailing edges. Sand as necessary.
