Step 15 - Wing Assembly (attach R6)
Fit the R6 assembly in
position. Make sure it is
vertical and the WB4 tabs are
properly inserted in the slots
of R6. When satisfied with
the fit and location, glue R6
in place.
Step 16 - Wing Assembly (trailing edge)
Remove one of the 1/4” x
1”x 36” balsa sticks. This will
form the trailing edge of the
wing. Measure and cut to
length.
This piece will slide into the
rear notches of all the ribs, as
shown here. When satisfied
with the fit and location, glue
to all of the ribs.
Be careful to keep glue out larger gap cut into
ribs R4-R6.
Step 17 - Wing Assembly (aileron leading edge)
Using the remainder of the
1/4” x 1” x 36” balsa stick
from the previous step,
measure and cut to form the
leading edge of the aileron.
This piece will slide into the
remaining rear notches of the
R4, R5 and R6 ribs, as shown
here.
When satisfied with the fit and location, glue to all of the ribs -
but
not to the trailing edge of the wing.
Step 18 - Wing Assembly (WT2)
Locate WT2 from BP1. The
tabs in this piece fit into the
slots on the rear of R6 as
shown here.
When satisfied with the fit
and location, glue it in place.
Step 19 - Wing Assembly (upper front sub-spar)
Locate one of the
3/16” square balsa
sticks. Measure and
cut to make the upper
front sub-spar. When
satisfied with the fit
and location, glue to
all of the ribs.
Step 20 - Wing Assembly (trailing edge sheeting)
Now locate one of the 1/16” x 4” x 24” balsa sheets. Measure and
cut a 3/4” strip the entire length of the piece to form the trailing
edge sheeting.
It fits in place as shown,
butting up against the
trailing edge balsa
strip.
When satisfied with the
fit and location, glue to
all of the ribs and the
trailing edge.
Step 21 - Wing Assembly (leading edge)
Now locate two of the 5/16” x 1/2”
x 36” balsa sticks. These are glued
together to form the leading edge of
the wing. As all stick balsa typically has
a slight warp (bend) to it, use a straight-
edge (a metal yardstick is shown here)
as an edge to press the pieces against
when gluing.
Note that the 5/16” edges should be
glued together to give you a 5/16” x
1” strip when finished.
Step 22 - Wing Assembly (leading edge)
The leading edge strip from the
previous step is now measured,
cut and glued into position as
shown here.
Step 23 - Wing Assembly (WB1)
Locate one WB1 from LP4. It is installed
a shown here, with the tab fitting into the
slot of the R2 rib. When satisfied with the
fit and location, glue in place.
Step 24 - Wing Assembly (TR1 / TR2)
Locate either one TR1 or one
TR2 from the LP1/2 sheets.
The one you choose will
depend on the powerplant
you will be using - specifically,
the weight of that powerplant.
For 99% of you, the longer
TR2 is the one to choose as it
will allow you to mount your
engine/motor further forward
- giving you better C.G. balance. If your motor is particularly heavy
say a larger 4-stroke, you might opt for the shorter TR1 piece.
Regardless of the one you choose, this piece is installed into the
open area between the R1 and R2 ribs as shown. Note that you will
need to also notch the leading edge strip installed in the previous
step to allow the TR1/2 piece to lie flat and true.
