Wing Construction Continued.
Check wing for twist. Sight along the bottom
portion of ribs
forward of the spar S1
.
Straight wings will have each rib bottom
parallel to the next. Warped wings will show
deviation from rib to rib. To correct a warped
wing: mist wing panel with glass cleaner, then
pin to a flat building surface. Once
completely dry, the wing will assume the
shape of the surface it has been pinned to.
Final sand wing. Then using a clear lacquer
or polyurethane based spray, apply a light
coat to seal the wood. We suggest “Deft”
brand “Clear Wood Finish”.
Use the covering guide on plan sheet 1 of 2
to cut the covering for your wing panels and
apply according to the directions provided by
your covering film manufacture. We suggest
AeroLITE covering film, available at
StevensAero.com
Cover only the top surface of the wing.
