INTRODUCTION

Congratulations on your purchase of the Top Flite
Cessna 182 ARF! The Cessna 182 ARF is built using
virtually the same airframe as the very successful
Top Flite Cessna kit. With the time consuming tasks
of building, covering, and painting already done for
you, you can be flying your scale Cessna after as
little as 15 to 20 hours of assembly! A pre-painted
ABS cockpit kit is included for added realism. The
corrugated control surfaces, functional pre-installed
flying lights, and generous use of fiberglass are details
you typically won’t find in other scale ARF planes.
Although the Cessna 182 ARF already includes an
impressive list of these “extras” right out of the box,
the sky is the limit for the amount of additional scale
detail you can create while assembling the Cessna to
be truly admired at the flying field or in competition.

Because of its 81" wingspan, the Top Flite Cessna 182
ARF is eligible to be entered at IMAA events. In order
to be IMAA-legal, some of the control components
and hardware may need to be replaced to conform
to Giant Scale rules even though this model does not
require heavy duty hookups.

For the latest technical updates or manual corrections
to the Cessna 182 ARF visit the Top Flite web site at
www.top-flite.com. Open the “Airplanes” link, then
select the Cessna 182 ARF. If there is new technical
information or changes to this model, a “tech notice”
box will appear in the upper left corner of the page.

IMPORTANT!!! Two of the most important things you

can do to preserve the radio controlled aircraft hobby
are to avoid flying near full-scale aircraft and avoid
flying near or over groups of people.

PROTECT YOUR MODEL,

YOURSELF & OTHERS.....FOLLOW

THESE IMPORTANT SAFETY

PRECAUTIONS

1. Your Cessna 182 ARF should not be considered
a toy, but rather a sophisticated, working model that
functions very much like a full-size airplane. Because
of its performance capabilities, the Cessna, if not
assembled and operated correctly, could possibly
cause injury to yourself or spectators and damage
to property.

2. You must assemble the model according to the
instructions. Do not alter or modify the model, as
doing so may result in an unsafe or unflyable model.
In a few cases the instructions may differ slightly from
the photos. In those instances the written instructions
should be considered as correct.

3. You must take time to build straight, true
and strong.

4. You must use an R/C radio system that is in
good condition, a correctly sized engine, and other
components as specified in this instruction manual.
All components must be correctly installed so that the
model operates correctly on the ground and in the air.
You must check the operation of the model and all
components before every flight.

5. If you are not an experienced pilot or have not
flown this type of model before, we recommend that
you get the assistance of an experienced pilot in your
R/C club for your first flights. If you’re not a member
of a club, your local hobby shop has information
about clubs in your area whose membership includes
experienced pilots.

6. While this kit has been flight tested to exceed
normal use, if the plane will be used for extremely
high stress flying, such as racing, or if an engine
larger than one in the recommended range is used,
the modeler is responsible for taking steps to reinforce
the high stress points and/or substituting hardware
more suitable for the increased stress.

7. WARNING: The cowl, wheel pants, wing struts,
tail cone, wing tips and landing gear legs included
in this kit are made of fiberglass, the fibers of which
may cause eye, skin and respiratory tract irritation.
Never blow into a part (wheel pant, cowl) to remove
fiberglass dust, as the dust will blow back into your
eyes. Always wear safety goggles, a particle mask
and rubber gloves when grinding, drilling and sanding
fiberglass parts. Vacuum the parts and the work area
thoroughly after working with fiberglass parts.

We, as the kit manufacturer, provide you with a top
quality, thoroughly tested kit and instructions, but
ultimately the quality and flyability of your finished
model depends on how you build it; therefore, we
cannot in any way guarantee the performance of
your completed model, and no representations
are expressed or implied as to the performance or
safety of your completed model.

Remember: Take your time and follow the
instructions to end up with a well-built model that
is straight and true.

DECISIONS YOU MUST MAKE

This is a partial list of items required to finish the
Cessna 182 ARF that may require planning or decision
making before starting to build. Order numbers are
provided in parentheses.

BUILDING STAND

A building stand or cradle comes in very handy
during the build. We use the Robart Super Stand II
(ROBP1402) for most of our projects in R&D, and it
can be seen in pictures throughout this manual.

RADIO EQUIPMENT

A 6-channel radio system such as a Futaba® 6EXAS with
a standard receiver and six standard size servos with a
minimum torque of 44 oz-in [3.2 kg-cm] are required for
the control surfaces of the Cessna 182 ARF.

One standard torque servo such as an S3003 is required
for the throttle. Two 24" [610mm] servo extensions
(aileron servos), six 12" [305mm] servo extensions
(ailerons, flaps and wing tip lights) and two Y-harnesses
(aileron and flap servos) are also required. A receiver

battery pack with a minimum capacity of 1000mAh is
recommended. A 600mAh receiver pack for the flying
lights is also required. Order numbers are provided:

ENGINE RECOMMENDATIONS

A .60 to .91 cu in [10 to 15cc] two-stroke or .90 to

1.20 [15 to 20cc] four-stroke engine is required. An
O.S.® .61 FX two-stroke engine installation is shown
in this manual and is plenty of power for scale flight
and mild aerobatic maneuvers. Throttle management
should be practiced if installing a larger engine. If a
two-stroke engine is installed, a Pitts-style muffler is
also required.

• BissonO.S..61SF/FXPittsMufer(BISG4061)

The Cessna 182 ARF also includes provisions for
installing a brushless out-runner motor and lithium­polymer batteries. Installation instructions are
detailed in this manual for a brushless power system.
The following components are recommended for the
best performance:

• GreatPlanes® RimFire™ 1.20 (50-65-450) Out-

packs simultaneously, it is recommended to
purchase an Equinox cell balancer for each
battery pack in order to minimize charge times
between flights.)

• APC16x8ThinElectricPropeller(APCQ4015)

SCALE COMPETITION

Though the Top Flite Cessna 182 ARF may not have
the same level of detail as an “all-out” scratch-built
competition model, it is a scale model nonetheless
and is therefore eligible to compete in the Fun Scale
class in AMA competition (we receive many favorable
reports of Top Flite models in scale competition!). To
receive the five points for scale documentation, the only
proof required that a full size aircraft of this type in your
paint/markings scheme did exist is a single sheet such
as a kit box cover from a plastic model, a photo, or a
profile painting, etc. If the photo is in black and white
other written documentation of color must be provided.
Contact the AMA for a rule book with full details.

If you would like photos of the full-size Cessna 182
for scale documentation, or if you would like to study
the photos to add more scale details, photo packs are
available from:

o 1. If you have not done so already, remove the

major parts of the kit from the box and inspect for
damage. If any parts are damaged or missing, contact
Product Support at the address or telephone number
listed in the “Kit Inspection” section on page 5.

o 2. Remove the tape and carefully separate all the

control surfaces. Use a covering iron with a covering
sock on medium/high heat to tighten the covering
if necessary. Apply pressure over sheeted areas to

thoroughly bond the covering to the wood.

HINGE THE AILERONS AND FLAPS

Do the right wing first so your
work matches the photos the
first time through. You can do
one wing at a time, or work
on them together. Also, we
suggest reading the entire
flap installation procedure
before beginning this
section so you will have an
understanding of how they
are hinged before gluing.

o o 1. Trim the triangular tabs from both sides of

three hinge points using a sharp hobby knife (protect
your fingers by holding the hinges with pliers while
trimming the tabs). Test fit (without glue) the hinge
points into the pre-drilled pockets in the flap and
wing so that the hinging direction of each hinge point
is parallel with the leading edge of the flap. Press the
hinge points into the pockets until the pin in each of
the hinge points is positioned over the flap hinge line
when the flap is in the up position as shown. Work
the flap up and down, ensuring that the flap moves
freely. When the flap is in the up position, it should sit
flush against the trailing edge of the wing.

7

Before performing steps 2 and 3, have denatured

Drill a 3/32" [2.4 mm] hole

1/2" [13mm] deep, in the center

of the hinge slot.

Cut the covering

away from the slot.

alcohol and some paper towel pieces ready for
epoxy cleanup.

o o 2. Make note how deep the hinge points fit into

the hinge pockets. Epoxy will be applied to the hinges
only on the portion that fits into the pockets. Remove
the flap from the wing panel and pull the hinge points
from the pockets. Coat the center of each hinge point
with petroleum jelly or oil. This will prevent epoxy
from sticking to the pivoting portion of the hinges and
will keep the hinges moving smoothly. Mix up a batch
of 30-minute epoxy. Use a toothpick or something
similar to coat the insides of the hinge point pockets
in the flap and the wing panel. Wipe away any excess
epoxy from around the pockets using a paper towel
dampened with alcohol.

o o 3. Coat the portion of each hinge point that fits

into the hinge pockets with epoxy. Insert the hinges
into the pockets in the flap and wing as was done in
step 1. Use a paper towel dampened with denatured
alcohol to clean up any epoxy. Work the flap up and
down to ensure it moves freely. Look at the flap from
the root rib and confirm that when the flap is all the
way in the up position, the top of the flap follows the
airfoil contour of the top of the wing. Also, confirm
that the flap is flush with the TE of the wing. Make
any small adjustments to the hinges as necessary.
When satisfied, set the wing aside and let the epoxy
cure undisturbed.

o o 5. Drill a 3/32” [2.4mm] hole 1/2” [13mm] deep

in the center of each hinge slot in the wing panel and
aileron. Use a sharp hobby knife to carefully cut away
the covering just around each hinge slot in the wing.

o o 4. Cut the included 2” x 9” [51mm x 229mm]

piece of CA hinge material into 3/4” x 1” [19mm x
25mm] individual hinges. Use a hobby knife or
scissors to trim the corners from each hinge to make
them easier to insert into the hinge slots.

to keep the hinge

centered.

INSTALL THE AILERON SERVO & LINKAGE

Before completing this section, confirm that the
servos that you will be using will properly fit between
the servo mounting block locations on the aileron
and flap servo hatch covers. Make adjustments as
necessary for your brand servos. The block locations
shown in this section will fit a standard size Futaba
brand servo.

o o 1. Use epoxy to glue the 3/4" x 3/4" x 5/16"

[19 x 19 x 8mm] hardwood servo mounting blocks to
the inside of the aileron hatch cover. Be sure that the
blocks are aligned over the rectangles with the grain
direction perpendicular to the covers as shown. Allow
the epoxy to cure undisturbed.

o o 6. Fit a CA hinge into each hinge slot in the

wing panel. If the hinges are difficult to install, use a
hobby knife to slightly enlarge the slots. Push a pin
(T-pins work well for this) through the middle of each
hinge to keep them centered.

o o 7. Fit the aileron to the hinges and align the root

edge of the aileron with the root of the trailing edge for
the aileron on the wing panel as shown. Remove the
pins from the hinges and position the aileron against
the trailing edge of the wing panel. The hinge gap
between the aileron and wing should only be wide
enough to allow a small line of light through. When
satisfied, apply 6 drops of thin CA glue to the center
of each hinge on both sides. When the CA has dried,
gently pull on the aileron to confirm that it is securely
glued in place.

o 8. Repeat steps 1-7 for the left wing panel.

o o 2. Cut three arms from a four-armed servo arm

included with the aileron servo. Enlarge the outer hole
of the remaining arm with a 5/64" [2mm] drill bit.

o o 3. Attach a 24" [610mm] servo extension to

each aileron servo and secure the connector using
tape or heat shrink tubing. Center the servos with
your radio system and install the servo arm to the
servo perpendicular to the servo case as shown. Be
sure to reinstall the servo arm screw into the servo.

o o 4. Position the servo against the underside of

the aileron servo hatch cover between the mounting
blocks. Shim the aileron servo away from the hatch
cover approximately 3/64" [1.2mm] to isolate it from
vibration (a business card folded in thirds works
well for this). Drill 1/16" [1.6mm] holes through the
mounting tabs on the servo case into the blocks.
Thread a servo mounting screw (included with the
servo) into each hole and back it out. Apply a drop of
thin CA to each hole to harden the wood. When the
CA has dried, install the servo onto the hatch cover
using the hardware supplied with the servo.

o o 5. Use the strings taped inside the aileron servo

hatches to pull the servo leads through the wing ribs.

o o 6. Thread a #2 x 3/8" [9.5mm] self-tapping

screw into each hatch mounting hole in the wing and
back it out. Apply a drop of thin CA to each hole to
harden the wood. Install the aileron hatch cover to
the wing as shown using four #2 x 3/8" [9.5mm] self­tapping screws.

o o 7. Thread a nylon clevis 15 complete turns onto

a 6" [152mm] pushrod. Slide a silicone clevis retainer
onto the clevis and connect the clevis to the outer
hole of a nylon control horn.

o o 8. Position the control horn onto the aileron

between the two corrugations that are inline with
the aileron servo arm. Align the holes in the control

horn directly over the aileron hinge line and mark the

location of the control horn mounting holes.

o o 9. Drill 1/16" [1.6mm] holes at the marks you

made through the plywood plate inside the aileron.
Do not drill all the way through the aileron! Thread a
#2 x 3/8" [9.5mm] self-tapping screw through each
hole and back it out. Apply a couple drops of thin CA
glue to each hole to harden the wood. When the glue
has dried, install the control horn onto the aileron
using two #2 x 3/8" [9.5mm] self-tapping screws.

pushrod where it crosses the outer hole in the servo
arm. Make a 90° bend at the mark on the pushrod
and cut off the excess pushrod 3/16" [4.8mm] beyond
the bend. Attach the pushrod to the servo arm using
a nylon FasLink. Thread the clevis up or down on the
pushrod as necessary to center the aileron with the
servo arm centered. Slide the silicone clevis retainer
to the end of the clevis to secure it.

o 11. Repeat steps 1 to 10 for the left wing panel.

turns. Install a silicone clevis retainer onto the clevis.
Measure 3-1/4" [83mm] from the clevis pin and make
a bend in the pushrod. Cut off the excess pushrod
3/16" [4.8mm] beyond the bend.

o o 10. Use tape or a small clamp to hold the

aileron in the neutral position. Make a mark on the

o o 1. As you did with the aileron, glue the mounting

blocks to the underside of the flap servo hatch cover.
When the epoxy has cured, attach the flap servo to
the hatch cover using the hardware included with the
servo. Center the servo with your radio system and
install a servo arm at a 30° angle as shown. The flap
servo does not require a servo extension.

o o 2. Prepare the flap linkage by threading a

nylon clevis onto a 4" [102mm] pushrod 15 complete

o o 3. Slide the pushrod through the access hole in

the wing and connect the bent end of the pushrod to
the outer hole in the flap control horn using a nylon
FasLink. Connect the clevis to the outer hole in the
flap servo arm. Put the flap servo hatch cover in place
onto the wing. While holding the hatch cover down,
use your radio system to test the operation of the flap.
Make any adjustments necessary to the position of
the clevis on the pushrod or the servo arm.
