Using the Manual
This manual is divided into sections to help make assembly
easier to understand, and to provide breaks between each
major section. In addition, check boxes have been placed
next to each step to keep track of each step completed.
Steps with a single box () are performed once, while
steps with two or more boxes () indicate that the step
will require repeating, such as for a right or left wing panel,
two servos, etc. Remember to take your time and follow the
directions.
Transmitter Requirements
The 3.1m Sukhoi requires a minimum of a 4-channel radio
to operate all the functions of your aircraft. However to get
the best performance from the Sukhoi, a radio with mixing
functions is recommended. We suggest the following radio
systems available through Horizon Hobby or your local
hobby distributor.

Wings will be setup with two different configurations,
precision and 3D. For the precision setup two servos will be
used one is mounted inboard and second servo outboard
of the wing. Middle servo bay will be left unused. This is
the configuration as the wings come out of the box. For 3D
setup, all 3 servos will be installed and middle servo control
horns need to be glued in. Follow the below steps.
be installed in.
2. Secure a 36-inch servo extension to the outboard
aileron servo lead using string or a commercially available
connector. This will prevent the extension from accidentally
disconnecting inside the wing.
4. A string has been installed in the wing to pull the
aileron servo extension through the wing. Tie or tape the
string to the end of the extension and pull the lead to the
wing root.
Precision Wing Setup
1. Prepare the aileron servos by installing the rubber
grommets and brass eyelets.
Hint: Prepare all servos for the wing at this time.
5. Mount the servo such that the output shaft faces the
leading edge and prepare the linkage for installation.
3. In order to harden the servo mounting holes in
the bays, mount the servo screws, back them out and
apply some thin CA in the hole. Wait until CA is dry before
installing the servo. Do this for every bay that a servo is to
7Hangar 9 3.1m Sukhoi SU-26MM ARF Assembly Manual
Page 8
6. Attach the linkage to the servo arm at the 1 inch
hole. If using aluminum JR arms, use the second hole from
center outward. Use threadlock on all the screws except for
the two setscrews of the arm.
7. To adjust the length of linkages, servos need to be
powered and at center. The arm should be mounted parallel
to the aileron hinge line; small adjustments can be made
using sub-trim. Adjust the length of linkage so the aileron is
centered and servo arm is parallel to the hinge line.
9. Mount the MatchBox™ in the wing root using sticky
back hook and loop. Before applying the hook and loop
to the MatchBox, apply masking tape to the back of the
MatchBox so it can easily be removed when need be.
MatchBox Programming Hints
The pointers below can help make matching servos easier.
This is not to take the place of the MatchBox instruction
manual.
1. Connect the inboard servo to the MatchBox and then
make all adjustments to servo center and travel adjustments
in the transmitter programming. No adjustments to this
servo should be made in the MatchBox.
8. Mount the inboard servo following the same method
as outboard but no extension is required.
8 Hangar 9 3.1m Sukhoi SU-26MM ARF Assembly Manual
2. Connect the second servo to the MatchBox to center it,
then install the servo arm onto the servo on the spline that
gets it as close to parallel with the hinge line as possible.
Then use the MatchBox to set the center of this servo so the
servo arm is exactly parallel to the hinge line. Now adjust the
linkage length so the hole in the ball link directly aligns with
the appropriate hole in the servo arm.
Now deflect the servo to full stick in one direction and use
the MatchBox to set the endpoint so the ball link directly
lines up with the hole in the servo arm. Repeat this with the
stick fully deflected in the opposite direction. Once the center
and both endpoints are set for the second servo, remember
Page 9
to turn the dial on the MatchBox back to the 0 position to
save the settings before powering off the receiver. Hint,
when adjusting for endpoints (full deflection), it is hard to
hold the sticks and adjust the MatchBox at the same time.
It is best to move the sticks to full deflection and while
holding the stick, turn off the radio. This will put the receiver
into hold and makes adjustment easier working only the
MatchBox and observing the linkage position over the servo
arm.
3D Wing Setup
1. 3D flying is more demanding and the addition of the
middle servo can help reduce the level of abuse servos and
wings will see. Open up the middle servo bay. Iron down the
edges. The middle servo bay is located approximately 16
inches away from the inboard servo. Rub your finger over
the covering in that vicinity to find it.
3. Find the location for control horns and remove the
covering in between the two slots. Now place the plate over
the slots and mark a slightly smaller area than the plate and
remove the covering.
2. To harden the servo mounting holes in the bay,
mount the servo screws, back them out and apply some
thin CA in the hole. Wait until CA is dry before installing the
servo. See step 3 in precision wing setup for detail.
4. Mix 30-minute epoxy and glue the horns and plate
such that the control horn pivot point is aligned with aileron
hinge line. Apply epoxy to both slots on the aileron and
control horn and plate. Clean excess with alcohol swabs.
9Hangar 9 3.1m Sukhoi SU-26MM ARF Assembly Manual
Page 10
5. Attach an 18-inch JR Heavy-Duty extension to the
middle servo. Mount the servo such that the output shaft is
towards the leading edge of the wing.
7. The picture below shows the wing with a 3-servo setup
at full deflection. For MatchBox setup, refer to previous
section.
The picture below shows the comparison of precision
wing and 3D wing setup.
6. 1.5-inch servo arms are used for 3D wing setup.
Assemble the linkages and use threadlock on all the screws.
Setscrews need only tightening and no threadlock.

Precision Setup
1. For precision setup one servo per elevator is used.
Prepare the servo by installing the rubber grommets and
brass eyelets.
Servo needs to be installed in such way that output shaft is
3. To harden the servo mounting holes in the bay
apply some thin CA in the hole. Wait until CA is dry before
installing the servo.
6. Connect the ball link to the 1.25-inch hole on a JR
aluminum servo arm. This would be the third outermost hole

Required Parts
Fuselage Rudder
Hinge rod
Required Tools and Adhesives
Drill Pliers
Petroleum Jelly/Industrial lubricant
1. Apply some industrial lubricant to the rod. Pass the
rod through the hinges in rudder and fuselage vertical fin
separately. This helps remove any possible dirt in the hinges
and makes for easier final assembly.
10. Glue opposite side of hook and loop to stab root
with CA.
11. Mount the MatchBox. Use 48-inch extension from
MatchBox to the receiver.
2. Mate the rudder and fuselage vertical stabilizer
and carefully pass the rod through hinges. This can be
accomplished by two ways. 1. Use a drill on slow speed
and gently pass through the rod. If there is any resistance,
back out and repeat. 2. Use a pair of pliers and push the rod
through the hinges. Make sure not to buckle the rod. This is
a rather slow process and needs attention.

The picture below is of the tail end of the pipe tunnel.
5. Temporarily mount the pipe mounts and install pipes
to center the mounts before they are glued. Use lubricant on
the pipes for easier passage through the mounts when they
are not glued yet. Pipe mounts will not touch the floor of
the fuselage and need to be glued to the sides and bottom
former.
6. Once mounts are centered mark the spot on the sides
and formers.
7. Remove the pipes and use an acid brush to apply
30-minute epoxy to the sides of the mount and fuselage.

pipe and header, such that is it forward the bump on the
header and over the grooves on the pipe/canister.
3. Once everything is assembled, heat the couplers where
clamps are using a heat gun at high setting. Do this for a few
minutes and allow some time for cooling. Repeat this one
more time. This will create a good grip and reduces chance
of pipe/header slipping out in flight. It is also recommended
to do this before the first flight. Let engine idle for 3 to 4
minutes to warm up the couplers, gradually increasing the
throttle to half to get the engine hot and then allow a cooldown period before the first flight. This should not need
repeating and when done right, header/pipe will not slip out.
Canisters Mount Installation
1. Kit comes with 2 canister mounts and silicone tubing.
There is only one support location for the canister mount
that is under the landing gear area. Scratch the surface of
each mount with a hobby knife and glue the layers using a
thin layer of 5 to 15-minute epoxy. Clamp until glue is cured.
Pass the silicone tubing through the mount start with top
middle hole and end at bottom middle hole as shown in
Pipes Mount Installation section.
2. Prepare the fuselage for canister installation. Remove
the covering as pictured in first bay, under the landing gear
and iron down the edges.
2. Insert the header and pipe into coupler, leave 1/8--1/4
inch gap between header and pipe. Slide the clamps on the

Canister/Header Assembly
1. Recommended header length for MTW TD110 canister
and DA-170 is 8--9-inches. Cut 1 inch off the stock header.
Assemble the canister/header using a vice-grip to open the
clamps and slide them over the header first then insert the
header and canister into coupler. Leave 1/8--1/4 inch gap
between header and pipe. Since the bump on the header has
to be cut for optimum performance, tap a button head 4-40
screw on the header and slide the slot of the clamp over the
button head screw and coupler to avoid slippage.
3. Temporarily mount the canister mounts and install
canisters to center the mount. Use lubricant on the canisters
for easier passage through the mounts before they are glued.
The canister mount touches the floor of the fuse and needs
to be glued to the sides and bottom former. Once mount is
centered, mark the spot on the sides and formers. Remove
the canisters and apply glue to the sides of the mount and
fuselage where they contact using 30-minute epoxy to
enough have time for adjustment.

3. Peel the decal and stick to the foam pilot panel.
Center of Gravity
An important part of preparing the aircraft for flight is
properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for your
model is 10.5 inches forward from the trailing edge of the
wing tip as shown. Mark the location of the CG on the top
of the wing with a felt-tipped pen.
Use help to lift the plane from the marked position.
For 3D flying 10 inches forward of trailing edge is
recommended; however, the 10.5 inches is the best overal
CG for both precision and 3D flying.
4. Glue the foam panel using foam-safe CA to the canopy.
5. Canopy bolts to the fuselage using 4 (4mm) screws
provided.
After the first flights, the CG position can be adjusted for
your personal preference.

Applying Decals
Kit comes with decal sets and all decals are die-cut. All large decals should be applied wet so the bubbles can be worked out by squeegee. Allow 24 hours for decals to dry and adhesive to
set.
It is important to take all the wrinkles in the covering out and would be best to apply the decals after the plane has been taken to a flying field a couple of times and all the wrinkles have
been removed. The following pictures show the location of decals.

Control Throws
Aileron:
Pro-Tips
1. Turn on the transmitter and receiver of your model.
Check the movement of the rudder using the transmitter.
When the stick is moved right, the rudder should also move
right. Reverse the direction of the servo at the transmitter if
necessary.
2. Check the movement of the elevator with the radio
system. Moving the elevator stick toward the bottom of the
transmitter will make the airplane elevator move up.
3. Check the movement of the ailerons with the radio
system. Moving the aileron stick right will make the right
aileron move up and the left aileron move down.
4. Use a throw meter to adjust the throw of the elevator,
ailerons and rudder.
Mike McConville has three flight modes as follows:
1. Normal: This flight mode is used for most precision
maneuvers.
2. Roller: This flight mode is used for spins, hammer head
and rolling circles. It has more rudder and elevator compared
to Normal flight mode.
3. High (3D): All surfaces at full deflection for 3D flying.
Mike’s plane uses 1% down elevator mix to throttle for down
lines and 5% up elevator to eliminate the pitch coupling in
knife edge. Please note this is very C.G dependant.
See Pro-Tips section for more details.

These are general guidelines measured from our own flight
tests. You can experiment with higher rates to match your
preferred style of flying.
Note: Travel Adjust, Sub-Trim and Dual Rates are
not listed and should be adjusted according to each
individual model and preference.
Important mixes that should be done correctly for precision
flying are as follows; this is besides the pitch coupling
mixes.
1. Downline Mix: Mike McConville’s plane needs only 1%
of down elevator that comes on at low end of idle. It is
important that this is done correctly to avoid inadvertent
down elevator when it is not needed.
2. For roller flight mode, Mike uses an elevator to elevator
mix that allows the elevator feel around center stick to be
the same as normal flight mode and increases elevator
throw at the extreme stick movement for spins and other
maneuvers that need extra elevator deflection. This is without
compromising the precision feel of the elevator.

Safety Do’s and Don’ts for Pilots
Check Your Radio
Before going to the field, be sure your batteries are
fully charged per your radio’s instructions. Charge the
transmitter and motor battery for your airplane. Use the
recommended charger supplied with your particular radio
system, following the instructions provided with the radio.
In most cases, the radio should be charged the night before
going out flying.
Before each flying session, be sure to range check your
radio. See your radio manual for the recommended
range and instructions for your radio system. Each radio
manufacturer specifies different procedures for their radio
systems. Next, run the motor. With the model securely
anchored, check the range again. The range test should not
be significantly affected. If it is, don’t attempt to fly! Have
your radio equipment checked out by the manufacturer.
Double-check that all controls (aileron, elevator, rudder and
throttle) move in the correct direction.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e., the correct direction and
with the recommended throws).
Check all the control horns, servo horns, and clevises to
make sure they are secure and in good condition.
Range Test Your Radio
Before each flying session, and especially with a new model,
it is important to perform a range check. It is helpful to have
another person available to assist during the range check. If
you are using a Spektrum transmitter, please refer to your
transmitter’s manual for detailed instructions on the range
check process.

2010 Official Academy of Model
Aeronautics Safety Code
GENERAL
1. A model aircraft shall be defined as a non-humancarrying device capable of sustained flight in the
atmosphere. It shall not exceed limitations established
in this code and is intended to be used exclusively for
recreational or competition activity.
2. The maximum takeoff weight of a model aircraft,
including fuel, is 55 pounds, except for those flown
under the AMA Experimental Aircraft Rules.
3. I will abide by this Safety Code and all rules established
for the flying site I use. I will not willfully fly my model
aircraft in a reckless and/or dangerous manner.
4. I will not fly my model aircraft in sanctioned events,
air shows, or model demonstrations until it has been
proven airworthy.
5. I will not fly my model aircraft higher than approximately
400 feet above ground level, when within three (3) miles
of an airport without notifying the airport operator. I will
yield the right-of-way and avoid flying in the proximity of
full-scale aircraft, utilizing a spotter when appropriate.
6. I will not fly my model aircraft unless it is identified with
my name and address, or AMA number, inside or affixed
to the outside of the model aircraft. This does not apply
to model aircraft flown indoors.
7. I will not operate model aircraft with metal-blade
propellers or with gaseous boosts (other than air),
nor will I operate model aircraft with fuels containing
tetranitromethane or hydrazine.
8. I will not operate model aircraft carrying pyrotechnic
devices which explode burn, or propel a projectile of
any kind. Exceptions include Free Flight fuses or devices
that burn producing smoke and are securely attached
to the model aircraft during flight. Rocket motors up
to a G-series size may be used, provided they remain
firmly attached to the model aircraft during flight. Model
rockets may be flown in accordance with the National
Model Rocketry Safety Code; however, they may not be
launched from model aircraft. Officially designated AMA
Air Show Teams (AST) are authorized to use devices
and practices as defined within the Air Show Advisory
Committee Document.
9. I will not operate my model aircraft while under the
influence of alcohol or within eight (8) hours of having
consumed alcohol.
10. I will not operate my model aircraft while using any drug
which could adversely affect my ability to safely control
my model aircraft.
11. Children under six (6) years old are only allowed on a
flightline or in a flight area as a pilot or while under flight
instruction.
12. When and where required by rule, helmets must be
properly worn and fastened. They must be OSHA, DOT,
ANSI, SNELL or NOCSAE approved or comply with
comparable standards.
RADIO CONTROL
1. All model flying shall be conducted in a manner to avoid
over flight of unprotected people.
2. I will have completed a successful radio equipment
ground-range check before the first flight of a new or
repaired model aircraft.
3. I will not fly my model aircraft in the presence of
spectators until I become a proficient flier, unless I am
assisted by an experienced pilot.
4. At all flying sites a line must be established, in front of
which all flying takes place. Only personnel associated
with flying the model aircraft are allowed at or in front of
the line. In the case of airshows demonstrations straight
line must be established. An area away from the line
must be maintained for spectators. Intentional flying
behind the line is prohibited.
5. I will operate my model aircraft using only radiocontrol frequencies currently allowed by the Federal
Communications Commission (FCC). Only individuals
properly licensed by the FCC are authorized to operate
equipment on Amateur Band frequencies.
6. I will not knowingly operate my model aircraft within
three (3) miles of any preexisting flying site without
a frequency-management agreement. A frequency
management agreement may be an allocation of
frequencies for each site, a day-use agreement between
sites, or testing which determines that no interference
exists. A frequency-management agreement may exist
between two or more AMA chartered clubs, AMA
clubs and individual AMA members, or individual
AMA members. Frequency-management agreements,
including an interference test report if the agreement
indicates no interference exists, will be signed by all
parties and copies provided to AMA Headquarters.
7. With the exception of events flown under official AMA
rules, no powered model may be flown outdoors closer
than 25 feet to any individual, except for the pilot and
located at the flightline.
8. Under no circumstances may a pilot or other person
touch a model aircraft in flight while it is still under
power, except to divert it from striking an individual.
9. Radio-controlled night flying is limited to lowperformance model aircraft (less than 100 mph). The
model aircraft must be equipped with a lighting system
which clearly defines the aircraft’s attitude and direction
at all times.
10. The operator of a radio-controlled model aircraft shall
control it during the entire flight, maintaining visual
contact without enhancement other than by corrective
lenses that are prescribed for the pilot. No model aircraft
shall be equipped with devices which allow it to be flown
to a selected location which is beyond the visual range
of the pilot.
