D D 5. Use the point of an Xacto knife to carefully chamfer

the inside edge of a 1/8" OD x 1-1/8" Brass Tube (BRST019).

Rough up the outside of the tube with course sandpaper and slide
it into the hole you just drilled until it is completely inside the flap,
with the chamfered end out.

D 9. Trial fit the two wing halves together using the wing

joiner. Sand the root of each panel if necessary to achieve a nice

close joint between the two wings. If there are large gaps fill them
with scrap balsa or filler.

FUSELAGE ASSEMBLY

ASSEMBLE FUSE SIDES

You'll need the following items:

SPT1F01 1/8" DC Balsa Front Fuse Sides
SPT1F02 1/8" DC Rear Fuse Side
SPT1F03 3/32" DC Balsa Front Fuse Doublers
SPT1F07 3/32" DC Balsa Rear Fuse Doubler &

Tripler

SPT1F11 1/8" Square Balsa Stringers

D D 6. Trial fit the flap in place on the torque rod and use
masking tape to hinge it. First check to see if the flap is aligned

UP and DOWN with the top surface of the wing. If it is not,

remove the tube and enlarge the hole up or down until it is. Then
check the movement, of the flap to make sure it does not bind when

the flap raises about 10 degrees or drops about 90 degrees. If it
does bind, push the tube in a little farther or check to make sure
both the brass tube and the unthreaded end of the torque rod are
perpendicular to the sub TE. When satisfied with the fit apply a
drop or two of thin CA around the middle of the tube. Allow the
CA to cure and then remove the flap and soak the area around the
tube (within an inch or so) with thin CA. Add med. or thick CA
to the bottom of the flap to fill any gaps but be careful not to get
any glue inside the tube. NOTE: If you had to enlarge the hole
a lot or you feel the wood is soft you can apply a very light layer
of glass cloth (3/4 to 2 oz.) over this area of the flap to help
strengthen it.

D D 1. Pin or tape the fuse plan to your flat work surface and
cover it with waxed paper. Pin one of the 1/8" Die-Cut Balsa
Front Fuse Sides (SPRTF01) down onto the FUSELAGE SIDE
VIEW making sure it is accurately lined up with the drawing.

Slide a 1/8" Die-Cut Balsa Rear Fuse Side (SPT1F02) into
place behind the front fuse side and align it with the plan. Press
the two pieces flat against the work surface and apply thin CA to
the joint. This is going to be the LEFT fuse side.

D D 7. Cut the aileron to fit between the flap and the wing tip.

Leave about a 1/16" gap at the tip end and a good 1/8" gap at the
flap end. Hinge the aileron in place with masking tape and then
reflex the flap up about 10 degrees. Move the aileron up and

down to make sure it will clear the flap without binding. Keep in
mind the covering will take up another 1/32" or so. NOTE: The
aileron is hinged on the top surface of the wing.

D D 8. Now go back and assemble the other wing panel.

D D 2. Check the punch holes in the 3/32" Die-Cut Balsa
Front Fuse Doublers (SPT1F03) to make sure they are punched

through the doubler. If not, poke a straight pin through each
punch mark. Trial fit the doubler onto the 1/8" Balsa Fuse Side.
The doubler should line up with the fuse where the canopy will
sit and in various other places. The arrows in the photo point out

these areas. Apply thin CA around the edges of the doubler and
in all of the former notches. Add a couple drops of thin CA to each

pin hole, one drop at a time allowing it to soak in.
