Construction Manual
Step 5 - Wing Assembly (attach R5)
Using medium CA, run a thin
bead of medium CA along
the inside, bottom surfaces
of the WB2s, where they
will contact the bottom spar.
Also place a line of glue on
the top of the spar where the
R5 assembly will attach. Now
attach the R5 assembly to the
spar, making sure the WB2s
rest flush on the building surface - just as shown in the photo.
This will insure a proper 90° angle for R5. Also make sure that the
bottom edges of both WB2s are properly glued to the bottom
spar.
This same technique of attaching the WB2s to the rib will be
used throughout the rest of the wing’s construction.
Step 6 - Wing Assembly (attach two R3s)
Now you’ll need two R3 ribs
from BP2 and four WB2 sheer
webs from BP6. Glue two WB2s
to each R3, referring to the
plans to make sure they are on
the correct side.
Using medium CA, run the
strips of glue just as before and
attach the first R3 up against the ends of the WB2 pieces from the
last step. Working your way inward, do the same for the other R3
as shown here.
Step 7 - Wing Assembly (attach two R4s)
Now you’ll need the R4 ribs
from the previous step. Locate
four WB2 sheer webs from
BP6. Glue two WB2s to each
R4, referring to the plans to
make sure they are on the
correct side.
Using medium CA, run the
strips of glue just as before
and attach one R4 up against the ends of the WB2 pieces from the
last step. Working your way inward, do the same for the other R4
as shown here.
Step 8 - Wing Assembly (attach two R3s)
Now you’ll need two R3 ribs
from BP2 and four WB2 sheer
webs from BP6. Glue two WB2s
to each R3, referring to the
plans to make sure they are on
the correct side.
Using medium CA, run the
strips of glue just as before and
attach one R3 up against the ends of the WB2 pieces from the last
step. Working your way inward, do the same for the other R3 as
shown here.
Step 9 - Wing Assembly (attach R2)
Locate two of the WB1s (from BP6) and one R2 from LP1. Note that
the WB1s have a slight angle on one end and there is a small circle
engraved. This angled side should face the inner (root) rib, with
angle tapering upwards (circle on top). Fit and glue both of these
to R2, then glue that assembly to the spar.
Step 10 - Wing Assembly (WH1 assembly)
Locate one WH1 and two R1As from
LP1. The two R1As fit into the slots
on either side of the wing dowel
hole. Pay close attention to the
orientation of this piece and glue
both R1As in place when satisfied.
Step 11 - Wing Assembly (attach WH1 & WH2)
Locate one WH2 from LP1 and the
WH1 assembly from the previous
step. Note that these two pieces also
have the same engraved circle and
slight angle on one side. This angled
side should face the inner (root) rib,
with angle tapering upwards (circle
on top). Using medium CA, glue these in place to the R2 rib as
shown here.
Step 12 - Wing Assembly (attach R1)
Locate one R1 rib from LP1 and take care when removing it as it
has two slots pre-cut between where the spars would fit. These
slots will allow the center portion of R1 to be removed later on, but
make sure R1 remains as a single rib for now.
Position R1 up against the ends of
the WB1, WH1 & WH2 pieces from
the previous step. Once all three
pieces are located properly, pin
the rear tab to the board. Lightly
tack the R1 to the WB1 pieces.
Then apply glue around the WH1
and WH2 pieces to make sure they are properly attached to the R1
and R2 ribs.
Step 13 - Wing Assembly (attach W4)
Locate one WH4 from LP1 and glue it in position, into the two
slots towards the rear of both R1 and R2. It will span between both
pieces.
Step 14 - Wing Assembly (cut trailing edge)
Measure and cut two of the
5/16” x 1/2” balsa strips
used to create the trailing
edge. Laminate these strips
together to form a single
5/8” x 1/2” piece, making
sure it is straight and true
while gluing. Once cured,
place the trailing edge strip on the step that is cut into each of
rib’s rear alignment tabs. Glue the trailing edge to the rear edge
of every rib, making sure that the 5/8” side is up against the edge
of the ribs.
