Construction Manual
Step 43 - Wing Assembly (center sheeting)
Just as you did in
step 29, it’s time
to use some of the
scrap 1/16” sheeting
from the BP pieces
to make the center
sheeting. You’ll also
have to cut a couple
of smaller strips to fill
the gap between the
edge of the servo mount and the edge of the R1 rib.
Step 44 - Wing Assembly (lower cap strips)
Now it’s time to install the
lower cap strips, using the
same technique as you did
when cutting and installing
the upper cap strips.
Again, these strips are pre-
cut in many of the 1/16”
laser cut sheets Use a few
lengths of this to make the
cap strips for the underside of the wing.
Cap strips are centered over each of the R2-R5 ribs. The cap strip
is flush with the edge of the R6 rib, resting against the T1 and T2
pieces already glued as part of the wing tip assembly.
Each cap strip runs from the back of the leading edge sheeting to
the front edge of the trailing edge sheeting.
Step 45 - Wing Assembly (aileron servo mount)
Locate one SH2 and one SH2D
from sheet LP3. These two
pieces are glued together as
shown to make the servo mount.
Note that we positioned the
etching so it won’t be visible
from the outside when it’s glued
in place on the next step.
Step 46 - Wing Assembly (aileron servo mount)
Locate the SH2 assembly from the
last step and glue it in position
as shown here, on the two rails
between the R4 ribs.
Step 47 - Wing Assembly (hinge reinforcement)
Locate the piece of leftover leading edge (two 5/16” x 1/2” pieces
glued together).
We recommend cutting smaller blocks to place inside the wing and
aileron as shown here. You’ll need
them glued in place where the
hinges are marked on the plans.
Doing this will give the hinges
and glue more surface for a better
bond later on.
Step 49 - Wing Assembly (tidying up radio hatch.)
Using a bit of 1/8” scrap from the
BP sheets, make two pieces to
“frame” the top and bottom of
the radio hatch opening. You’ll
need to notch them slightly so
they will be flush with the cap
strips.
The purpose of these 2 pieces is
to aid in covering later on - no real structural gain - just to make
things look better down the road.
Step 50 - Wing Assembly (port wing construction)
Set the starboard wing half aside and begin work on the left (port)
wing half. Tape the left wing plan and fresh wax paper on your
board. Then follow steps 1 through 49 to complete the left wing
half. Once finished, then move on to step 51.
Step 51 - Elevator Assembly
Tape the stabilizer/
elevator plan and
fresh wax paper on
your board.
Locate the two S4
pieces from BP9
and the two S3
pieces from BP15. These form the elevator halves as shown here.
Using your straight edge as shown will help align the two halves
perfectly to each other. Pin the S3 pieces in place first, then glue
the S4 pieces in place.
Step 52 - Elevator Assembly (elevator joiner)
Locate the 1/4” dowel
from the hardware bag.
Measure and cut the dowel
to form the joiner as shown
here. Glue this place with
thicker CA, or better yet,
a bit of epoxy.
This joint
must be strong, so don’t try to get away with a little thin CA
to tack in in position.
Step 53 - Elevator Assembly (ribs)
Locate a 1/4” square balsa strip and
use it to cut the “ribs” that form the
interior of both elevator halves.
Glue these in position when
satisfied with the fit.
Step 54 - Elevator Assembly (sheeting)
Locate the four ELV SHEET pieces
from BP20. These are glued to the top
and bottom of the elevator halves.
Note the slight difference between
the inside and outside curves. Lightly
sand the elevator assembly then glue
on the sheeting.
When the glue has cured, remove the elevator and attach ELV
SHEET pieces to the other side after a light sanding.
