2. Test fit the assembled wing hold-down plate into the
fuselage, placing the larger plate downward and locking it
into the fuse sides. Sand or trim the plate to achieve
the best fit. Remove the plate and glue it in place using
30-minute epoxy.
❏
3. Position the wing on the fuselage with the centerline
of the wing along the centerline of the fuselage. Hold a
string (with one end attached to a pin centered at the tail)
out to a wing tip. Put a piece of tape on the string to mark
the intersection of the string and the wing tip. Swing the
string over to the other wing tip and check to see if the
distances are the same. Make slight adjustments to the
angle of the wing until the distances from the tail to the
wing tips are equal.
❏
4. Once the wing is aligned to the fuselage, use a 5/32"
drill bit to drill through the wing and into the wing hold-down
plate. When drilling, be sure that the drill bit remains
square to the wing bolt plate in all directions.
❏
5. Enlarge the holes in the mounting blocks to 3/16". A
prop reamer or 3/16" drill bit may be used for this operation.

6. Slide one of the
4mm washers
onto one of the
4mm
wing hold-down bolts
. Slide the bolt through the wing
hold-down plate. Thread one of the
blind nuts
with the
“pronged” side up partially onto the wing hold-down bolts
from the underside of the wing hold-down plate. Put a
small drop of 30-minute epoxy on the prongs, then draw it
up into the wing hold-down plate by tightening the bolt.
Repeat this process for the other blind nut.
❏
7. Slide the bolt/washer combination from the last step
through the wing from the top. Slide one of the rubber
O-rings onto the bolt from the bottom. The O-ring keeps the
bolt from falling out during transport.
