Construction Manual
Step 89 - Stab/Elevator (finished)
Once the glue has set, remove the finished elevator from the plans.
Prepare your work area
Position the fuselage side plan over the surface and tape into
position. Cover it with waxed paper and tape that over the plan.
Step 90 - Fin Assembly (RD1 )
Locate both RD1 pieces from
sheets BP1. Carefully stack
them and glue them together
to form a 1/4” thick RD1 piece.
Step 91 - Fin Assembly (fin trailing edge)
Measure and cut the two
pieces of 1/4” x 1/4” square
that make up the trailing edge
of the vertical fin.
Pin the longer (rear most)
piece in position, then glue
the shorter piece in place as
shown on the plans.
Step 92 - Fin Assembly (RD1 install)
Take the RD1 assembly, position and glue it into position.
Step 93 - Fin Assembly (bottom edge)
Locate two RD2’s from sheet BP2. Carefully stack them and glue
them together to form a 1/4” thick RD2 piece. Pin in position as
shown on the plans glue in place.
Step 94 - Fin Assembly (leading edge)
Measure and cut the fin’s leading edge from 1/4” square strip. Pin
in position and glue into place.
Step 95 - Fin Assembly (fin ribs)
Measure and cut the fin’s internal
ribs from a 1/4” square strip. Take
care to match the angles for a
good fit. Pin these in position and
glue into place.
Remove two G gussets from BP3.
Glue together to form a 1/4” thick
piece. Glue in place.
Step 96 - Rudder (leading edges)
Once the glue has set, remove the vertical fin from the plans, then
measure and cut the rudder’s leading edge, made from two pieces
of 1/4” x 1/4” strip glued together. Pin in position.
Step 97 - Rudder (RD3 & RD4)
Locate both RD3 and RD4 pieces
from sheets BP1. Carefully stack
both RD3’s and glue them together
to form a 1/4” thick RD3 piece.
Stack both RD4’s and glue them
together to form a 1/4” thick RD4
piece.
Step 98 - Rudder (RD3 & RD4 install)
Take the RD3 and RD4 assemblies, position and glue them into
position.
Step 99 - Rudder (trailing edges)
Measure and cut the rudder’s trailing edge pieces from 1/4” x 1/4”
strip. Pin and glue in position.
Step 100 - Rudder (rudder ribs)
Measure and cut the rudder’s
internal ribs from a 1/4”
square strip. Take care to
match the angles for a good
fit. Pin these in position and
glue into place.
Step 101 - Rudder
Once the glue has set, remove the finished rudder from the plans.
Step 101 - Fuselage Assembly (sanding tail pieces)
Also take the time to sand the horizontal stabilizer, elevator, vertical
fin and rudder pieces. The leading edge of each piece should be
rounded. Slowly work this rounded edge around the tips of the
stab and elevator, as well as the vertical fin and rudder.
Step 102 - Fuselage Assembly (front wing hold fit)
Now it’s time to attach the wing to the fuselage. Dry fit it in place
and make sure that the dowel fits nicely into the pre-cut hole in F3.
If the fit is a bit tight, lightly sand (or use a reamer) to enlarge the
hole slightly. Do this a little at a time as you don’t want a sloppy fit.
The fit should be so that the dowel can easily be inserted/removed
without force.
Step 104 - Fuselage Assembly (fuse/wing alignment)
To align the wing properly
on the fuselage, push the
dowel into the F3 and allow
the wing to sit in the wing
saddle of the fuselage. The
wing is perfectly aligned with
the distance from left wing tip
to the rear of the fuselage is the
same the distance when measured
from the right wing tip.
With the wing aligned, drill two 3/16” holes for the wing bolts.
Using the precut holes in the WH6/WH7 assemblies as a guide
(already installed in the wing), drill down through the WH8/WH9/
WH10 assemblies on each side of the fuselage.
Use caution to make sure the wing does not move until both holes
are drilled.
Step 105 - Fuselage Assembly (tap WH8/WH9/WH10)
Remove the wing from the fuselage. Using a 1/4-20 tap, use it to
tap both holes drilled into the WH8/WH9/WH10 assemblies. Use
thin CA to wick into the threads to harden the wood. Once the glue
has cured, run the tap through one more time to clear out any glue
that might be in the cuts.
Drill the through-holes in the wing with a 17/64 drill so the wing
bolts can slip through easily.
