INTRODUCTION

Congratulations on the purchase of your Cirrus SR22 ARF.

This is one of the fi nest fi berglass ARF aircraft we have ever

produced. This plane will get everyone’s attention at the
club fi eld. The quality of the fi berglass fi nish and attention
to detail is great. This plane is within the capability of the
average to intermediate pilot. Assembly is quick and easy.

We are sure the Cirrus SR22 ARF will bring you many hours

of fl ying enjoyment.

For the latest technical updates or manual corrections to the

“Cirrus SR22 ARF” visit the Great Planes web site at www.

greatplanes.com. Open the “Airplanes” link, then select the

“Cirrus SR22 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.

Academy of Model Aeronautics

We urge you to join the AMA (Academy of Model Aeronautics)

and a local R/C club. The AMA is the governing body of
model aviation and membership is required to fl y at AMA
clubs. Though joining the AMA provides many benefi ts,

one of the primary reasons to join is liability protection.
Coverage is not limited to fl ying at contests or on the club
fi eld. It even applies to fl ying at public demonstrations and

air shows. Failure to comply with the Safety Code (excerpts

printed in the back of the manual) may endanger insurance

coverage. Additionally, training programs and instructors are
available at AMA club sites to help you get started the right
way. There are over 2,500 AMA chartered clubs across the
country. Contact the AMA at the address or toll-free phone
number below:

Or via the Internet at: http://www.modelaircraft.org

IMPORTANT!!! Two of the most important things you can
do to preserve the radio controlled aircraft hobby are to
avoid fl ying near full-scale aircraft and avoid fl ying near or
over groups of people.

SAFETY PRECAUTIONS

DECISIONS YOU MUST MAKE

Protect Your Model, Yourself & Others…

Follow These Important Safety Precautions

1. Your Cirrus SR22 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 Cirrus SR22 ARF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.

2.

You must assemble the m odel according to the instructions.

Do not alter or modify the model, as doing so may result in an

unsafe or unfl yable 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 specifi ed
in this instruction manual.

5.

You must correctly install all R/C and other components so

that the model operates correctly on the ground and in the air.

6. You must check the operation of the model before every

fl ight to insure that all equipment is operating and that the

model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.

7. If you are not an experienced pilot or have not fl own
this type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for your

fi rst fl ights. 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.

8. While this kit has been fl ight tested to exceed normal
use, if the plane will be used for extremely high stress

fl ying, 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.

9. WARNING :
gear included in this kit are made of fi berglass, the fi bers of

which may cause eye, skin and respiratory tract irritation. Never

blow into a part (wheel pant, cowl) to remove fi berglass 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 fi berglass parts. Vacuum the parts and
the work area thoroughly after working with fi berglass parts.

The fuselage, cowl, wheel pants and landing

This is a partial list of items required to fi nish the Cirrus

SR22 ARF that may require planning or decision making
before starting to build. Order numbers are provided in
parentheses.

IMPORTANT BUILDING NOTES

● When you see the term test fi t in the instructions, it means
that you should fi rst position the part on the assembly

without using any glue, then slightly modify or custom

fi t the part as necessary for the best fi t.

● Whenever the term glue is written you should rely upon
your experience to decide what type of glue to use. When
a specifi c type of adhesive works best for that step, the
instructions will make a recommendation.

● Whenever just epoxy is specifi ed you may use either
30-minute epoxy or 6-minute epoxy. When 30-minute
epoxy is specifi ed it is highly recommended that you use
only 30-minute epoxy, because you will need the working
time and/or the additional strength.

● Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following
steps to get another view of the same parts.

●

The Cirrus SR22 ARF is factory-covered with Top Flite
MonoKote Jet White fi lm (TOPQ0204). Should repairs
ever be required, MonoKote can be patched with additional
MonoKote purchased separately. MonoKote is packaged
in six-foot rolls, but some hobby shops also sell it by the
foot. If only a small piece of MonoKote is needed for a
minor patch, perhaps a fellow modeler would give you
some. MonoKote is applied with a model airplane covering
iron, but in an emergency a regular iron could be used. A
roll of MonoKote includes full instructions for application.

● The stabilizer and wing incidences and engine thrust
angles have been factory-built into this model. However,
some technically-minded modelers may wish to check
these measurements anyway. To view this information
visit the web site at www.greatplanes.com and click on

“Technical Data.” Due to manufacturing tolerances which

will have little or no effect on the way your model will fl y,
please expect slight deviations between your model and
the published values.

PREPARATIONS

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.

2. Remove the tape and separate the aileron and fl ap servo

❏

covers from the wing. Use a covering iron with a covering
sock on medium heat to tighten the covering if necessary.

Apply pressure over sheeted areas to thoroughly bond the

covering to the wood. If any adhesive from the tape is left
behind, a paper towel dampened with lighter fl uid can be
used to remove the adhesive.

3. Give the ailerons and fl aps a pull to check that the

❏

hinges are securely glued. This should also be done between
each fl ight.

3.

❏ ❏

the two 3/16" x 3/8" x 1/2" [4.8 x 9.5 x 12.7mm] hardwood

blocks to the bottom of the aileron servo cover.

Use a T-pin to prick small holes in the bottom of the blocks
and the servo cover to help the glue hold more securely.
Be careful to not poke the T-pin through the servo cover.

Noting the grain direction, use 6-minute epoxy to glue

ASSEMBLE THE WINGS

Start the assembly with the left wing so that the pictures
match your assembly.

Install the Aileron Servo

1. Connect a 16" [406mm] servo extension to one of

❏ ❏

the aileron servos. Cut a piece of black heat shrink tubing
in half. Slide the heat shrink tubing over the connector. Shrink
the tubing by heating it.

2.

❏ ❏

the aileron servo on the bottom of the aileron servo cover so
that the servo arm output shaft is centered in the opening.

Install the eyelets and grommets in the servos. Position

4. Once the epoxy has cured, place a 1/32" [.8mm]

❏ ❏

spacer such as a piece of cardstock from a header card

or a piece of paper folded several times, under the servo,

between each mounting block. After the servo is installed
the spacer will be removed providing adequate spacing for
vibration isolation.

5. Drill 1/16" [1.6mm] holes through the blocks for the

❏ ❏

servo mounting screws. Mount the servo to the blocks with
the screws that came with the servo. Remove the servo

mounting screws and apply a couple of drops of thin CA in
each hole to harden the threads. Allow the CA to fully harden.

Then, reinstall the servo and remove the spacer.

6

6. Use the string in the wing to pull the aileron servo

❏ ❏

wire through the wing.

7. Plug the aileron servo into your receiver, switch on

❏ ❏

the transmitter and receiver and center the aileron servo
trim. Position a servo arm on the aileron servo so that it is
perpendicular to the aileron servo.

8. Place the aileron servo cover with the servo in the

❏ ❏

wing. Be certain that the cover is positioned correctly as

shown. Use the servo cover as a guide to drill 1/16" [1.6mm]
holes through the plate in the wing. Secure the cover using
four #2 x 3/8" [9.5mm] sheet metal screws and four #2 fl at
washers. Use thin CA to harden the screw threads.

10. Position the control horn so that it is inline with

❏ ❏

the aileron servo horn and the clevis pin is aligned with the
aileron hinge line. On the aileron, mark the two mounting

holes. Remove the control horn and drill a 1/16" [1.6mm]

pilot hole at each mark. Do not drill completely through the
aileron. Attach the control horn using two #2 x 3/8" [9.5mm]

sheet metal screws. Use thin CA to harden the holes.

11 Center the aileron servo and aileron. Mark the pushrod

❏ ❏

where it meets the outer hole of the servo arm. Remove the

pushrod from the aileron control horn and make a 90° bend
at the mark. Reinstall the pushrod on the aileron control horn.
Insert the L-bend in the aileron servo arm and secure it with a

nylon Faslink. Cut the pushrod 1/32" [.8mm] past the Faslink
and slide the clevis retainer over the clevis.

9. Thread a nylon clevis 20 turns onto the end of a

❏ ❏

2-56 x 4" [102mm] metal pushrod. Slide a silicone clevis
retainer over the clevis. Install the clevis in the outer most

hole of a nylon control horn.

7

Install the Flap Servo

1. Connect a 9" [229mm] servo extension to one of the

❏ ❏

fl ap servos. Cut a piece of black heat shrink tubing in half.
Slide the heat shrink tubing over the connector. Shrink the

tubing by heating it.

the same procedure used to install the aileron servo.

❏ ❏

through the wing.

Install the fl ap servo on the fl ap servo cover following

3. Use the string in the wing to pull the fl ap servo wire

Use the servo cover as a guide to drill 1/16" [1.6mm] holes
through the plate in the wing. Secure the cover using four #2
x 3/8" [9.5mm] sheet metal screws and four #2 fl at washers.
Use thin CA to harden the screw threads.

6. Thread a nylon clevis 20 turns onto the end of a 2-56

❏ ❏

x 4" [102mm] metal pushrod. Slide a silicone clevis retainer
over the clevis. Install the clevis in the outer most hole of a

nylon control horn.

7. Position the control horn so that it is inline with

❏ ❏

the fl ap servo horn and the base of the control horn is 1/4"

[6.4mm] from the trailing edge of the wing. On the fl ap, mark
the two mounting holes. Remove the control horn and drill a

1/16" [1.6mm] pilot hole at each mark. Do not drill completely

through the fl ap. Attach the control horn using two #2 x 3/8"

[9.5mm] sheet metal screws. Use thin CA to harden the holes.

4. Plug the fl ap servo into your receiver. Position the

❏ ❏

fl ap dial or slider on the transmitter to the fl ap up position.
Position a servo arm on the fl ap servo so that it is rotated

towards the trailing edge of the wing. Move the fl ap control
to check that the servo arm does not hit the fl ap servo cover.

5. Place the fl ap servo cover with the servo in the wing.

❏ ❏

Be certain that the cover is positioned correctly as shown.

8. With the fl ap in the up position and the servo arm

❏ ❏

rotated back, mark the pushrod where it meets the hole

11/16" [17.5mm] from the center of the servo arm. Remove

the pushrod from the fl ap control horn and make a 90° bend
at the mark. Reinstall the pushrod on the fl ap control horn.
Insert the L-bend in the fl ap servo arm and secure it with a

nylon Faslink. Cut the pushrod 1/32" [.8mm] past the Faslink
and slide the clevis retainer over the clevis.

9. Return to step one of Install the Aileron Servo and

❏

install the aileron and fl ap servos in the right wing panel
(page 6).

Install the Main Landing Gear

1. Locate the fi berglass left main landing gear by

❏ ❏

fi tting the main gear in the recess in the left wing. If a glow

engine will be installed, fuelproof the main landing gear
recess with thin CA or epoxy thinned with denatured alcohol.

4. Apply a drop of thread locker to the threads of a

❏ ❏

6-32 x 1/4" [6mm] socket head cap screw. Slide a 4mm
wheel collar onto the axle. Thread the 6-32 x 1/4" [6mm]

socket head cap screw into the wheel collar and tighten it on
the fl at at the end of the axle.

2. File a 1/4" [6.3mm] long fl at spot on the end of the

❏ ❏

main landing gear axle.

3. Insert the axle through the main landing gear and

❏ ❏

the left wheel pant. Slide an axle nut onto the axle followed
by a 2" [51mm] foam wheel. Tighten the axle nut on the axle.

5. Apply a drop of thread locker to the threads of four

❏ ❏

6-32 x 1/2" [12.7mm] socket head cap screws. Secure the

main landing gear to the wing with the cap head screws.

6. Use epoxy to glue the nylon wing dowel in the root

❏ ❏

of the wing. Position the dowel so that 1/2" [12.7mm] of the

dowel is protruding from the wing.

7. Go back to step 1 of Install The Main Landing Gear

❏ ❏

and install the right main landing gear.

ASSEMBLE THE FUSELAGE

Install the Stabilizer

1. Insert the carbon fi ber wing joiner tube in the fuselage.

❏

Slide the two wing halves onto the tube and secure the wing

halves to the fuselage with two 1/4-20 nylon wing bolts.

4.

Use epoxy to glue the two 1/8" x 5/8" [3 x 16mm] nylon

❏

stabilizer dowels 5/16" [8mm] into the root of the stabilizers.

2. Test fi t the elevator halves on the stabilizer halves

❏

using the six pivot point hinges. The two hinges that are
inserted in the elevator halves at the tip need to be shortened

1/8" [3mm]. Note on one side of the elevator halves there is

a hardwood plate under the covering for the elevator control
horn screws. This side should be face downward.

3. Place a piece of tape on the left elevator half and the

❏

left stabilizer half to identify that they go together. Remove
the elevator halves from the stabilizer halves. Insert the
elevator joiner wire in the elevator halves and place the
assembly on a fl at surface. Check that both trailing edges of
the elevators are fl at on the surface. If they are not, remove
and bend the elevator joiner wire slightly and check again.

Also mark the left side of the elevator joiner wire.

5. Slide the 5/16" x 9-3/4" [8 x 248mm] aluminum

❏

stabilizer joiner tube through the fuselage. Temporarily

install the two stabilizer halves on the aluminum stabilizer

joiner tube.

6. View the plane from the aft end. Check that the stabilizer

❏

and wing are parallel to each other.

7. Remove the stabilizer halves and tube. Use sandpaper

❏

to roughen the aluminum tube. Clean the tube with a

paper towel dampened with denatured alcohol. Reinstall
the aluminum tube, centering it in the fuselage. Mark the
aluminum tube on both sides of the fuselage where they

meet. Pull the tube out one side so that glue can be applied

between the lines (do not apply the glue yet).
