A FEW WORDS ABOUT
OPTIONAL LIGHTING
Scale lights make a model like this Cessna come to life. We added a rotating beacon, dual landing lights and position lights (see page 5 for part numbers). The rotating beacon is powered by a 9V transistor battery and a miniature circuit board that allows you to vary the “rotation” speed. The beacon and position lights are turned on via a simple toggle switch hidden within the cowling. The landing lights are powered directly from the flight- pack battery and are plugged into the receiver. By activating a sixth channel, we can turn the lights on and off from the transmitter. You could also “Y” the landing lights into the throttle or flap servo so when either is operated, the lights would come on.
Pockets built-in to the cowl greatly simplify
the installation of landing lights. The wiring was modified to include a “Deans” connector and a firewall-mounted plug so the cowling can be removed without having to cut the wires.
The circuit boards and 9V battery were
wrapped in foam rubber and installed under the servo tray along with other electronic components.
❏ 1. Epoxy the 5/16” x 3/4” x 7/8” hardwood
Servo Mounting Blocks to the die-cut 1/16” ply Flap and Aileron Servo Hatches. Install the Flap and Aileron servos as shown in the photo and on the plans.
After “fishing”
the servo wires
through to the opening at the center of the wing, plug them into a “Y” harness. Before permanently screwing the servo hatches in position, hook up your radio and set
centering
and
direction
of both sets of servos.
❏ 2. Drill 3/32” holes through the Servo Hatches
at each of the six punch marks. Position the hatches in their respective openings, then drill 1/16” pilot holes into the hatch support rails. Use #2 x 3/8” flat head sheet metal screws to install the servo hatches.
❏ 3. Install the Aileron Horns in line with the
pushrod exits as shown on the plans. Drill 1/16”
holes into the Ailerons at the proper horn locations. Screw the horns in place with #2 x 3/8” sheet metal screws.
NOTE: Put a couple of drops of thin CA into each screw hole before reattaching the horns.
❏ 3. Four .074 x 4” Threaded End Rods are
supplied to make the Flap and Aileron pushrods. Screw a nylon Clevis and silicone Retainer on each pushrod. The Flap pushrods are connected to the servos using nylon Faslinks
™
as shown in the photo. Aileron
pushrods are attached to the servos with solder clevises. Hook up and adjust the Aileron and Flap linkages. Refer to the Control Surface Throws section for movement recommendations.
❏ 4. Permanently install the Elevator (as
described on page 42 in Steps 3 & 4) and the Rudder (page 43, Steps 4 & 5).
❏ 1. Wrap the Receiver and Battery in 1/2” foam
rubber (Hobbico HCAQ1050) securing the foam with rubber bands.
❏ 2. Protect both components from fuel leakage
by sealing them in plastic wrap or plastic bags. Seal the plastic closed with masking tape.
