31. Sheet (cross grain) the wing saddle area
with leftover 1/16" balsa wing sheeting. Trim and
block sand edges of the sheeting to blend with the
fuse sides and the wing saddle.
WING MOUNTING
❏
1. Draw an accurate centerline on both the wing
and the fuse to aid you in the wing mounting
process.
❏
2. Drill a 5/16" hole in the LE of the wing
through the existing hole in the forward dowel plate
(DP) and through the aft dowel plate (ADP).
❏
3. Round the ends of the 5/16" x 3-3/8" dowel
and install it into the hole you drilled. Trial fit the
wing onto the fuse. Make any adjustments to the
wing and fuse necessary for a good fit. If the dowel
alignment is interfering with the wing fit, “oblong” the
hole in the forward dowel plate using a round file.
❏
4. Epoxy the dowel into the wing so it protrudes
about 1/2" forward of the LE.
❏
5. Mark the tapered hardwood bolt plate with
a centerline. Put two lines 1-1/2" outside the
centerline on the non-tapered (square) side of the
block. Drill two 3/16" pilot holes 3/8" behind the
front (thick) edge of the block. Refer to plan for
exact locations.
❏
6. Cover the aft portion of the wing saddle with
waxed paper. Place the wing in the wing saddle.
Use masking tape to hold the wing securely in
place. Carefully align the wing visually and with the
centerlines you drew.
❏
7. Cut a piece of 1/16" balsa to fit in the wing
saddle behind the wing. Glue it to the aft edge of
the wing.
❏
8. Epoxy the tapered hardwood bolt plate to the
aft edge of the wing and the 1/16" balsa sheet (see
photo at step 10).
❏
9. Push a T-pin into the center of F-12. Tie a
piece of string to the pin. Use the string to check
the distances between the pin and the wingtips.
They should be equal .
