29. Drill a ¼" hole through the wing and wing mounting plate at the
marks made in the previous step. Insure the drill is straight and the
wing is aligned and held securely in place.
30. Enlarge the fuselage wing mounting plate holes to 19/64" and
install the 1/4-20 metal blind nuts securely on the back side using CA
or epoxy. Note: Do not use the nylon 1/4-20 bolts to set the blind
nuts in the plywood because they are not strong enough. The best
way is to use a spare 1/4-20 metal bolt or strong pliers.
31. Bolt the wing to the fuselage and test fit the belly pan to the cen-
ter of the wing bottom
32. If your belly pan doesn’t fit exactly (turned up edges, wrong con-
tour, etc) you can adjust it by taping the edges with masking tape
and using a heat gun to soften the fiberglass while carefully pressing
it into place with a gloved hand. You may need to go over it a cou-
ple times, letting is cool in between. Note: Be careful not to bend the
fiberglass too much while it is cool or the paint will crack.
33. Once you have a good fit, remove the tape on one side of the
belly pan and mark a line on the wing at the edge of the belly pan.
Repeat for the other side.
Belly Pan Mounting: The belly pan is made using very heavy duty
fiberglass and is very inflexible. We made it extra rigid so it won’t
collapse if you lift the plane by the belly pan or have a gear up land-
ing. Due to this, every belly pan may not match the wing contour
exactly. We have listed some steps to make for a better fit.
