similar posts from the remaining pieces, sanding the ends flat.
Position the aileron servo on the bottom of the aileron servo covers
so the servo arm output shaft is centered in the opening.
On the bottom of each aileron
hatch, glue one post on each
side of the servo as shown in the
photo.
Note that the left hatch is a
mirror image of the right hatch
and we’ve etched an arrow that
should point towards the front
of the airframe.
Now fit the servo hatches into position on the bottom of the wing.
Using the pre-cut holes as a guide, drill four 1/16” mounting
holes into the 3/16” x 3/8” basswood mounting strips installed
earlier. Harden the wood with a bit of thin CA and you can use the
supplied 2-56 x 3/4” self tapping screws to secure them in place.
Step 119 - Servo rails
Using leftover 3/16” x 3/8”
basswood, measure and cut two
strips that will span across the
TRAY, directly above the lower
hatch. These should be spaced
so your rudder and elevator
servos can be mounted to them.
When satisfied with the fit and
position, glue them in place.
If using a glow or gas engine,
measure and cut 2 more strips.
These will be used for the
throttle servo mount. Mount
one strip on TRAY, just behind
F5, then the other to span between the fuselage sides. It will need
to be spaced for the width of your throttle servo. When satisfied
with the fit and position, glue them in place.
Step 120 - Ailerons (control horn mount)
Each aileron needs a strip of
3/16” x 3/8” basswood glued in
place as shown here. Note the
location of it on the plans, then
measure, cut and glue this in
position for each aileron.
Step 121 - Ailerons (hinge supports)
Use leftover 1/4” x 1/2” balsa
scraps to cut twelve 1” pieces
that will be glued in place for
the aileron hinge supports.
Note the hinge locations on
the plans, then glue the blocks
in place inside the trailing edge
of the wing and inside the leading edge of the ailerons. Do this for
both wing halves.
Step 122 - Airframe Assembly (sanding)
Now take the time to go over the entire airframe and give it a
good, final sanding. Make sure everything is flush and smooth, that
the wings are airfoil shaped along their entire width and everything
is ready for covering.
Step 123 - Ailerons (hinging)
Now it’s time to hinge the ailerons.
Note that the hinges will NOT be
glued in place at this time. This is
simply to cut the slots and hold
the aileron in place temporarily for the next step. Note each of
the hinge positions on the plan, then cut the slots for the aileron
hinges. These hinges installed along the top edge of the aileron as
shown in this diagram.
Step 124 - Control horns
With the ailerons still temporarily in place, also temporarily fit the
rudder in place as it’s time to mount the control horns.
Make sure that when installing the control horns, they are placed
in-line with the pushrods cutouts, and that the line of holes where
the clevises attach are positioned over the hinge line.
Use a 1/16” bit, to drill the proper holes for the aileron horns
as they will be held in with 2-56 x 3/4” self tapping screws, not
requiring the plastic backer.
The rudder and elevator horns are held in with 2-56 x 3/4” machine
screws and will use the plastic backer plates. Drill these slightly
larger with a 3/32” bit.
Step 125 - Tailwheel mounting
Mount your choice of tailwheel to the bottom of the fuselage.
It should mount to the bottom of the plywood TW1 assembly,
already installed.
Step 126 - Radio and Pushrod Installation
Although you can install the
radio after covering your
model, we find it easier to
get everything in place before
covering. This way you have
unblocked access inside the
fuselage and wings to get
the servos, extensions, and
pushrods in place.
Shown here are several photos
with sample installations in the
wing and fuselage.
Finish the installation of your radio
gear by adding the receiver, flight
pack battery and the switch. We
mounted the receiver to the fuselage
side using a bit of self-adhesive
hook-and-loop (not included).
