Step 11.
Using a 1/4" drill bit, carefully drill through the wing
at the indents in the bottom of the wing. Be careful when the drill
bit exits the top of the wing that you do not tear the covering.
Note:
When you drill the wing bolt holes, be sure to drill the
holes perpendicular to the top surface of the wing.
Step 12.
After you have drilled the wing for the wing bolts, trial
fit the wing into position on the fuselage. Carefully thread each
bolt just a few turns into the installed blind nuts in the fuselage.
Note:
If the wing bolt holes are not perfectly aligned and you
can’t get the bolts to thread into the blind nuts, care-
fully use a round file and enlarge the hole in the wing.
It only requires that a small amount of material be
removed. The wing bolts may be hard to turn when
you first install them but will get easier in time. Be
careful not to cross-thread the bolts into the blind
nuts. Remove the wing bolts.
Step 13.
Locate the wing bolt hold-down plate. Note the wing
bolt hold-down plate has holes already drilled for the wing bolts.
The holes in the wing bolt plate have the same spacing as the
preinstalled blind nuts in the fuselage. Carefully remove the cov-
ering over the predrilled openings using a sharp hobby knife.
Step 14.
Insert the wing bolts through the wing bolt plate
(covered side up) and insert the bolts through the wing bolt
holes in the wing.
