Step 3 - Lower spar
Locate one of the 3/8” square
basswood strips. This will be
the lower spar. Position over
the plan, measure the length
and cut, leaving an extra 1/4”
or so past the R1 position.
Then tack-glue this piece to
the waxed paper to hold it in
place using a few small drops
of medium CA instead of t-pins. Be sure it is aligned properly and is
straight over it’s entire length. The alignment of this spar is critical
as the rest of the wing panel is based off this single piece.
Step 4 - Wing Assembly (outer wing tip)
The wing panels are
constructed from the
outside (tips), in towards
the center (root).
Remove parts R8A from
BP3 and R8B from BP2.
These pieces fit
together as shown here.
When satisfied with the fit, glue them together.
Step 5 - Wing Assembly (outer wing tip)
Locate R8 from BP2 and
T1, T2, T3, T4 and T5
from BP5. The T1-T5
braces will slide into the
notches on the R8A/B
assembly from the last
step. Pay attention so
these are in the correct
order.
Then gently slide this sub-assembly into the notches in the R8A/B
assembly from the last step. When satisfied with the fit, glue them
together.
Step 6 - Wing Assembly (attach R8 assembly)
Position the R8 assembly
in position. Make sure it
is vertical and pin the rear
tab to the building board.
Do not glue yet.
Remove one WF4 from
BP8 and one WB4 from
BP9. These sheer web
pieces have a small circle
etched into the upper,
outside corner showing the side that should be fitted into the R8
assembly.
Fit as shown and make sure that the tabs completely slide into the
slots in R8 as this will guarantee that R8 is held in vertically. When
satisfied with the fit, glue R8 and WF4 to the bottom spar.
Step 7 - Wing Assembly (attach R6)
Locate one R6 rib from BP2, one WF3 from BP8 and one WB3
from BP9. Position R6 up against the ends of the WB3 pieces from
the last step. Once located properly, pin the rib’s rear tab to the
board, then fit the WF3
and WB3 sheer webs in
place. When satisfied
with the fit and location,
glue these pieces in
place.
Step 8 - Wing Assembly (attach two R7s)
Next you’ll need two R7
ribs from BP1, two WF3
webs from BP8 and two
WB3 webs from BP9.
Position one R7 up
against the ends of the
WB3 webs from the
previous step. Once
located properly, pin
the rear tab to the
board, then fit WF3 and
WB3 in place. When satisfied with the fit and location, glue these
in place. Working your way inward, attach the other R7, WF3 and
WB3 pieces in place.
Step 9 - Wing Assembly (servo hatch rails)
Locate one of the 3/16”
x 3/8” pieces left over
from step 1. Measure
and cut two 4” lengths.
Carefully slide these
into the pre-cut holes in
R7 to create the servo
hatch rails. Glue these
in position.
Step 10 - Wing Assembly (attach R6)
Locate one R6 rib from
BP2, one WF3 from
BP8 and one WB3 from
BP9. Position R6 up
against the ends of the
WB3 pieces from the
last step. Once located
properly, pin the rib’s
rear tab to the board,
then fit the WF3 and
WB3 sheer webs in
place. When satisfied
with the fit and location, glue these pieces in place.
Step 11 - Wing Assembly (attach R5s)
Locate three R5 ribs from BP3 and BP4, two WF3 webs from BP8
one WF2 from BP8 and three WB3 webs from BP9.
Working inward, locate these one at a time using the same
techniques you have used for the previous ribs. Glue one set of R5,
