Congratulations on the purchase of the Great Planes
Revolver .6 1 ARF! After the great success of the .46 Revolver
and your many requests for a larger version, we are proud
to bring you the Revolver .61. This plane was designed for
the average sport pilot who wants 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 lo mcevaks are all within the
capabilities of this airplane. We have incorporated many
features found only on larger airplanes. The plug-in wings,
composite landing gear, and a removable canopy for easy
access to the inside of the fu selage are all 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 .61 ARF. If there is new technical information or
changes to this mod el a “tech noti ce” b ox will appear in t he
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 to ll-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-sc ale 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 per formance
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 th e model, as doing
so may result in an unsafe or unfl yable model. In a few
cases the instructio ns may dif fer slight ly from th e 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 radi o system that is in fi rst-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.

We, as the kit manufacturer, pro vide 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.

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
Revolver .61 ARF that may require planning or decision
making before starting to build. Order numbers are
provided in parentheses.

Radio Equipment

5. You must correc tly install all R /C and other co mponents
so that the model operates correctly o n the ground and in
the air.

6. You must check the operatio n of the mo del 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 connector s often and re place 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 mod el 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 tr act irritation. Never blow into a part
to remove fi berglass dust, as the dust will blow back into
your eyes. Always wear saf ety goggles, a particle mask and
rubber gloves when grinding, drilling and sanding fi berglass
parts. Vacuum the parts and th e work area th oroughly after
working with fi berglass parts.

The Revolver .61 ARF requires a minimum 4-c hannel radio
system with fi ve 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 require d
for the aileron servos. If you are using a radio system that
does not suppor t mixing functio ns, 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"
[1 52mm] servo extension for the ESC. If you plan to install a
glow engine, you will need a 12" [305mm] servo extension
for the receiver battery 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 p lane.

IMPORTANT BUILDING NOTES

30-minute epoxy is specifi ed it is highly recommended that
you use only 30- minute (or 45 - minute) ep oxy, 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. T o view this information visit the web
site at www.greatplanes.com and click on “Technical Data.”
Due to manufacturing tolerances w hich 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.

PREPAR ATIONS

1. If y ou have not done so already , remove the major parts

❏

of the kit from the box and inspec t 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.

2. Drill a 1/16" [1.6mm] hole in the hatch covers

❏ ❏

through the mounting 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.

3. 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.

BUILD THE WING

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 neces s ary for your brand servos. The b l ock
locations shown in this section will fi t a standard size Futaba
brand servo.

1. Use epoxy to glue the 11/16" x 11/16" x 5/16"

❏ ❏

[17.5mm x 17.5mm x 7.9mm] hardwood servo mounting
blocks to the insides of the hatch covers. Be sure that
the blocks are aligned over the rectangles with t he grain
direction perpen d i c ular to t he covers as shown. Allow the
epoxy to cure.

4. Attach a 6" [152mm] servo extension to the aileron

❏ ❏

servo and secure the conne ctor 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 reinst all the ser vo
arm screws into the servos.

5. Position the servos against the underside of the

❏ ❏

aileron servo hatch covers between the mounting blocks.
Drill 1/16" [1.6mm] holes through the mount ing tabs on the
servo cases 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 servos onto the hatch
covers using the hardware supplied with the servos.
