Congratulations on the purchase of the Great Planes
Revolver .46 ARF! This sport plane was designed for the
average sport pilot who is looking for an airplane that looks
good, fl ies fast, and is capable of performing a wide range
of aerobatic maneuvers. Loops, rolls, positive and negative
snap rolls, hammerheads, and lomcevaks are all within the
capabilities of this airplane. We have incorporated many
features found only on larger airplanes. Things such as plug­in wings, composite landing gear, and a removable canopy
for easy access to the inside of the fuselage are features you
will come to appreciate.

For the latest technical updates or manual corrections to
the Revolver ARF visit the Great Planes web site at www.
greatplanes.com. Open the “Airplanes” link, then select
the Revolver 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.

AMA

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.

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.

PROTECT YOUR MODEL, YOURSELF

& OTHERS...FOLLOW THESE

IMPORTANT SAFETY PRECAUTIONS

1. Your Revolver 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 Revolver, 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 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 fi rst-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.

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: The cowl and wheel pants 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 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.

We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished 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.

DECISIONS YOU MUST MAKE

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

Radio Equipment

The Revolver .46 ARF requires a minimum 4-channel radio
system with four 50 oz.-in. [3.6 kg-cm] minimum standard
servos. If you are installing a glow engine, an additional
standard servo is required for the throttle.

In addition, two 6" [152mm] servo extensions are required
for the aileron servos. If you are using a radio system that
does not support mixing functions, a Y-harness will also be
required to connect the aileron servos to the receiver.

If you plan to install a brushless motor, you will need a 6"
[152mm] servo extension for the ESC. If you plan to install a
glow engine, you will need a 12" [305mm] servo extension
for the receiver pack.

A charge jack receptacle is optional, but is useful for recharging
the receiver pack without removing the canopy hatch and
is shown in the assembly of the plane. Recommended part
numbers for the radio components are provided below:

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 (or 45-minute) epoxy or 6-minute epoxy. When
30-minute epoxy is specifi ed it is highly recommended that
you use only 30-minute (or 45-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 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”
on the previous page.

❏ 2. Carefully remove the tape and separate all the control

surfaces. Use a covering iron with a covering sock on high
heat to tighten the covering if necessary. Apply pressure over
sheeted areas to thoroughly bond the covering to the wood.

❏ ❏ 3. Test fi t a CA hinge into each of the hinge slots in the

wing panel and aileron. If necessary, enlarge the slots with
a hobby knife. When satisfi ed with the fi t, insert a CA hinge
halfway into each hinge slot in the wing panel. Push a pin
through the middle of each hinge to keep them centered.

BUILD THE WING

Install the Ailerons

❏ 1. Cut the included 2" x 9" [51mm x 229mm] CA hinge

strip into 3/4" x 1" [19mm x 25mm] individual hinges. Clip
the corners of each hinge to make them easier to insert into
the hinge slots.

❏ ❏ 2. Drill a 3/32" [2.4mm] hole 1/2" [13mm] deep into

the center of each hinge slot in the aileron and wing panel.
Trim the covering away from each hinge slot to ensure that
the hinges will be properly glued in place.

❏ ❏ 4. Join the aileron to the wing panel and remove the

pins from the hinges. Center the aileron on the wing.

❏ ❏ 5. Adjust the aileron so there is a small gap between

the LE of the aileron and the wing. The gap should be small,
just enough to see light through the gap or to slip a piece of
paper through.

❏ ❏ 6. Apply six drops of thin CA to the top and bottom of

each hinge without using accelerator. After the CA glue has
hardened, confi rm that the aileron is secure by pulling on it
and defl ecting it up and down.

❏ 7. Repeat steps 2-6 for the other wing panel.

Install the Aileron Servos & Pushrods

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

❏ 1. Drill a 1/16" [1.6mm] hole through the aileron servo hatch

covers in the center of each etched rectangle on the inside of

the covers.

blocks approximately 3/8" [9.5mm] deep. Thread a #2 x 3/8"
[9.5mm] fl at head wood screw into each hole and back it out.
Apply a drop of thin CA glue to each hole to harden the wood.
When the CA glue has dried, thread a #2 x 3/8" [9.5mm] fl at
head screw into each of the four holes.

ENLARGE TO

5/64" [2mm]

CUT OFF

UNUSED ARM

❏ 4. Cut three arms from a four-armed servo arm for each

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

❏ 2. Use epoxy to glue the 11/16" x 11/16" x 5/16" [18mm x

18mm x 8mm] hardwood servo mounting blocks to the insides
of the hatch covers. 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.

❏ 3. With the epoxy completely cured from step 2, continue the

1/16" [1.6mm] holes in the hatch covers through the mounting

❏ 5. Attach a 6" [152mm] servo extension to each aileron

servo and secure the connector using tape or heat shrink
tubing (not included). Center the servos with your radio
system and install the servo arms to the servos perpendicular
to the servo cases as shown. Be sure to reinstall the servo
arm screws into the servos.

❏ 6. Position the servos against the underside of the aileron

servo hatch covers between the mounting blocks. Drill 1/16"
[1.6mm] holes through the mounting tabs on the servo cases
into the blocks. Thread a servo mounting screw (included

8

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 servos onto the hatch covers using the
hardware supplied with the servos.

❏ 9. Thread a nylon clevis 20 complete turns onto each 6"

[152mm] pushrod. Slide a silicone clevis retainer onto each
clevis and connect the clevises to the outer holes of two
control horns.

❏ 7. Use the strings taped inside the aileron servo hatches

to pull the servo leads through the wing ribs.

❏ 8. Position the aileron servo hatch covers in place and

drill a 1/16" [1.6mm] hole through the mounting holes and
into the hatch mounting blocks. Thread a #2 x 3/8" [9.5mm]
self-tapping screw into each hole and back it out. Apply a
drop of thin CA to each hole to harden the wood. Install the
hatch covers to the wings using eight #2 x 3/8" [9.5mm] self­tapping screws and eight #2 fl at washers.

❏ 10. Position the control horns over the plywood plates in the

ailerons (if you cannot see them, hold the aileron at a shallow
angle in good lighting or use a small pin to puncture the
covering) using the position of the servo arms as a guide. Align
the holes in the control horns directly over the aileron hinge line
and mark the location of the control horn mounting holes.

9

❏ 11. Drill 1/16" [1.6mm] holes at the marks you made

through the plywood plates. Do not drill all the way through
the ailerons! 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 horns onto the ailerons using
four #2 x 3/8" [9.5mm] self-tapping screws.

cross the outer holes in the servo arms. Make a 90 degree
bend at the mark on the pushrod and cut off the excess pushrod
1/4" [6mm] beyond the bend. Attach the pushrods to the servo
arms using nylon FasLinks. Thread the clevises up or down
on the pushrods as necessary to center the ailerons with the
servo arms centered. When satisfi ed, slide the silicone clevis
retainers to the ends of the clevises to secure them.

❏ 1. Use epoxy to glue the anti-rotation pins into the holes

in the root ribs of the wing panels near the leading edge.
The pins should protrude from the root ribs approximately
5/8" [16mm]. Use a paper towel dampened with denatured
alcohol to wipe away any excess epoxy.

❏ 2. Slide the aluminum wing tube into the fuselage

aligning the hole in the center of the wing tube with the hole
in the fi berglass tube in the fuselage.
