Owner manual
❏ 8. Remove the wing. Tap 1/4-20 holes into the
holes drilled in the wing bolt blocks. Add a few drops
of thin CA to the threads, allow to fully harden, then
retap the threads.
❏ 9. Enlarge the bolt holes in the wing with a 17/64"
[6.7mm] drill, then bolt the wing to the fuselage with
two 1/4-20 x 2" [50mm] nylon wing bolts. Cut holes in
the bottom sheeting to accommodate the heads of
the bolts.
❏ 10. Test fit the wing to the fuselage and bolt it down
with two 1/4-20 x 2" [50mm] nylon bolts. See how it
looks and make any adjustments where necessary.
BUILD THE BELLY PAN
❏ 1. Cut a 20" [510mm] belly pan side from a 1/4"
x 3/4" x 30" [6.4 x 19 x 760mm] balsa stick. Make
another belly pan side the same way. Save both 10"
pieces for the front and back.
❏ 2. Mark the middle of one of the belly pan sides.
Place it on the bottom of the fuselage aligning the
line with the glue joint in the middle of the bottom
sheeting. Lay a ballpoint pen on the bottom of the
wing and mark the curvature of the wing onto the
belly pan side. Also mark the stick at the front and
back of the wing saddle in the fuselage.
❏ 3. Cut the belly pan side at the marks on both
ends, then cut it on the curvature line you marked.
Reposition the belly pan side and mark another
curvature line, then cut again. Once more, mark,
then cut. Now the belly pan side should fit the wing
well. Trim where necessary for a good fit.
❏ 4. Make the other belly pan side the same way.
❏ 5. Pin a leftover 3/16" x 3/16" [4.8 x 4.8mm] balsa
stick along one side of the fuselage under the wing.
This will reveal the location of the belly pan side
making a smooth transition between the front and
the back of the wing saddle. Use a ballpoint pen to
draw the location of the belly pan side along the
balsa stick. Mark the other side of the bottom of the
wing the same way.
❏ 6. Glue the belly pan sides to the bottom of the
wing along the lines.
Refer to this photo for the following three steps.
❏ 7. Use the remaining two 1/4" x 3/4" x 10" [6.4 x
19 x 250mm] balsa sticks to make the front and back
of the belly pan. Glue the sticks into position.
Hint: Use thin cardstock to shim the front and back
of the belly pan away from the fuselage.
