tube. Adjust the wing saddle bases so they are
contacting the fuselage root ribs, then glue
only the
saddle bases
to the fuselage.
❏
12. Align the bottom of the fuse root rib on both
wings with the
bottom
of the wing saddle bases at
the rear (pivoting the wings about the joiner tube).
Clamp both wing panels to the saddle bases near the
aft wing bolt block.
❏
13. Place an incidence meter on one wing panel
at rib 8 and read the incidence. Check the incidence
of the other wing panel at rib 8. Adjust both wing
panels until the incidences are the same, keeping in
mind that the rear of both root ribs should align with
the bottom of both wing saddle bases.
❏
14. Now that you have confirmed that both wings
are at the same incidence, remove the panels, apply
epoxy to the ends of the joiner box on both sides of
the fuse, reposition both wing panels and clamp
them into position. Recheck the incidence of both
panels, make adjustments if required, and do not
disturb the model until the epoxy cures.
❏
15. Remove the clamps and finish gluing both
fuse root ribs to the fuse.
Now, the only way to get the wing off the fuse is to
use your 7/64" ball driver!
For clarity, we took the wing off the fuse in this photo
(plus, this thing won’t fit in our photo studio with the
wings on!).
❏
16. With both wing panels still bolted to the fuse,
glue leftover 1/4" x 1/4" balsa sticks along the bottom
of both fuse root ribs permanently joining them to the
top longeron and the saddle bases.
Important
: If you
plan to do aggressive aerobatics, use leftover
basswood sticks as reinforcement.
❏
17. Remove the wing panels. Bevel the aft, curved
edge of the wing saddle base. Trim the top of formers
3, 4 and 5 so they are even with the top of the fuse
root rib to accommodate the top wing fillet.
❏ ❏
18. Test fit, then glue the die-cut 3/32" balsa
top wing fillet
to the fuse root rib, saddle base and
the top longeron. Glue an additional leftover 3/32"
balsa strip on top of the fuse root rib continuing the
fillet to the top of former 3.
❏ ❏
19. Sand the edge of the top fillet even with the
root rib. Bolt the wing to the fuse and check the fit.
Build the top fillet for the other side of the fuse the
same way.
❏ ❏
20. Glue the die-cut 3/32" balsa
bottom wing
fillet
to the bottom of the ply wing saddle base. Glue
an additional leftover 3/32" balsa strip on the bottom
of the fuse root rib continuing the fillet to former 3.
❏ ❏
21. Sand the bottom fillet even with the root rib,
then sand the end even with the top fillet, neatly
blending it to the fuse.
❏
22. Build the other bottom fillet the same way,
then bolt the wings to the fuse and blend the fillets
neatly to the wing and fuse.
Mount the servos
Note:
The following instructions show how to mount
the servos in the forward of two optional mounting
locations. For illustration in this manual, the forward
location is chosen due to the size and weight of the
engine used in the prototype. If you are using a
heavier ignition engine, your model may come out
nose heavy, so you may choose to mount your
servos in the aft location.
