In the world of competition aerobatic airplanes, the
Russian Sukhoi SU-26m is the equivalent of a top fuel
dragster that can turn on a dime. Its combination of
absurd amounts of horsepower, light weight, rugged
construction and amazing agility allows aggressive
pilots to perform to the limits of their physical
endurance.
E-flite perfectly captures the essence of this aerial hot
rod with its Sukhoi SU-26m – a scaled-down version of
the Hangar 9 Sukhoi SU-26m designed by world-class
IMAC competitor Mike McConville. The E-flite SU-26m
features an exceptionally lightweight airframe that was
designed around the powerful Park 480 BL outrunner
motor (sold separately). As with the full-scale Sukhoi,
this combination of lightweight construction and
prodigious power gives the E-flite SU-26m unlimited
performance that is ideally suited for 3D aerobatics.

Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly
more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications.
All manufacturer’s instructions and warnings
must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always
follow the manufacturer’s instructions when
disposing of Lithium Polymer batteries.
An RC aircraft is not a toy! If misused, it can cause
serious bodily harm and damage to property. Fly
only in open areas, preferably at AMA (Academy of
Model Aeronautics) approved flying sites, following all
instructions included with your radio.
Keep loose items that can get entangled in the
propeller away from the prop, including loose clothing,
or other objects such as pencils and screwdrivers.
Especially keep your hands away from the propeller.
During the course of building your Sukhoi SU-26m,
we suggest that you use a soft base for the building
surface. Such things as a foam stand, large piece of
bedding foam or a thick bath towel will work well and
help protect the model from damage during assembly.

Aileron Hinging
Required Parts
Wing (left and right)
Aileron (left and right)
CA hinges (8)
Required Tools and Adhesives
T-pins Thin CA
Pin drill Paper towel
Hobby knife with #11 blade
Drill bit: 1/16-inch (1.5mm)
1. Locate the positions for the hinges. Drill a 1/16-
inch (1.5mm) hole in the center of each slot of both
the wing and aileron. This creates a tunnel for the
CA, allowing the CA to penetrate into the hinge
better, bonding the hinges more securely.
2. Slide four hinges into the slits in the aileron.
Center the slot in the hinge with the hole drilled in
Step 1. Place a T-pin in each hinge to prevent it
from being pushed into the wing when installing
the aileron.
Do not use CA accelerator during the hinging
process. The CA must be allowed to soak into the
hinge to provide the best bond. Using accelerator
will not provide enough time for this process.
3. Slide the aileron into position. Check to make
sure it can move without interference at the wing
root and wing tip. Remove the T-pins and apply
Thin CA to each hinge. Make sure the hinge is fully
saturated with CA. Use a paper towel to clean up
any excess CA from the wing and aileron. Make
sure to apply CA to both sides of the hinge.
8 E-flite Sukhoi SU-26m 480 ARF Assembly Manual
Placing a #11 hobby blade between the aileron
leading edge and wing trailing edge to position
the aileron will result in a nice free-moving
hinge for 3D throws without any binding.
4. Firmly grasp the wing and aileron and gently
pull on the aileron to ensure the hinges are secure
and cannot be pulled apart. Use caution when
gripping the wing and aileron to avoid crushing
the structure.
5. Work the aileron up and down several times to
work in the hinges and check for proper movement.

2. Place the servo in the wing. Guide the servo
lead out through the opening at the wing root.
4. Apply 2–3 drops of thin CA into each hole to
harden the surrounding wood. This will make the
screws more secure and less likely to vibrate loose.
6. Use 6-minute epoxy to attach the control horn to
the aileron.
3. Use a pin drill and 1/16-inch (1.5mm) drill bit
to drill two holes through the servo mounting tabs
into the wing. Use care not to drill through the top
of the wing by accident.
5. Use a #1 Phillips to secure the aileron servo
using the screws provided with the servo.
7. Use a #0 Phillips screwdriver to remove the stock
servo horn from the aileron servo.
10 E-flite Sukhoi SU-26m 480 ARF Assembly Manual
8. Place a 3D servo horn on the aileron servo.
The horn should align with the hinge line when the
radio is on and the aileron servo plugged into the
receiver. There are an odd number of splines on the
servo, so you may need to remove the horn and
rotate it 180 degrees to get it to align correctly.
9. Use side cutters to remove the arm from the servo
horn that does not align with the control horn.
10. Use a pin drill and 1/16-inch (1.5mm) drill bit
to enlarge the outer hole of the aileron servo horn.
11. Attach the micro control connector to the servo
horn. Be sure to use the included retainer to secure
the micro control connector.
13. With the radio system on, make sure to center
the aileron trim and stick. Make sure the aileron
servo is operating properly using the transmitter.
Insert the z-bend of the 31/2-inch (89mm) pushrod
into the center hole of the aileron control horn.
Slide the pushrod wire through the micro connector
on the servo horn. Center the aileron, and secure
the position of the wire using the 2mm x 4mm
screw and a #1 Phillips screwdriver.
12. Secure the servo horn prepared in the last
few steps using the screw from the servo and a #0

the wing and stab are parallel. If not, lightly sand
the stab saddle until they are.
3. Measure from the stab tip to the wing tip. Adjust
the stab until the measurements are equal.
5. Use a sharp hobby knife to cut the covering
slightly inside the lines drawn. Be very careful not
to cut into the underlying wood, as this will weaken
the stab and cause it to fail in flight.
You can use a soldering iron instead of a knife. This
will eliminate the chances of cutting into the wood.
6. Insert the micro control horn into the slot in the
elevator. Make sure the holes in the control horn
face forward and that the horn is on the side with
the clear covering (bottom).
7. Slide the micro control horn backplate on the

Final Assembly
Required Parts
Fuselage Canopy
Battery Battery hatch
Hook and loop tape
Hook and loop strap
Pilot (optional)
Required Tools and Adhesives
Canopy glue Low tack tape
Medium CA Waxed paper
1. With the aircraft fully assembled, install the
battery into the battery compartment. Secure the
battery using the hook and loop tape and the hook
and loop straps.
2. Use medium CA to glue the pilot (optional) to
the canopy hatch as shown.
3. Place the canopy hatch on the fuselage. Make
sure to place a piece of waxed paper or part of a
bag from the packaging of your model between the
hatch and fuselage so when the canopy is glued
to the hatch it won’t accidentally be glued to the
fuselage. Make sure that the hatch is fully seated
on the fuselage, and the magnet in engaged during
this step. If it is not seated and engaged, it could
cause your hatch to fit improperly or not engage
once the canopy is glued on.
Place a piece of hook and loop tape on the bottom
of the battery and on the fuselage where the
battery rests. This will keep the battery from shifting
forward or backward during extreme maneuvers.
4. Use canopy glue to secure the canopy to the
hatch. Use low-tack tape to keep the canopy in
opposition on the fuselage until the glue fully cures.

Control Throws
1. Turn on the transmitter and receiver of your
Sukhoi SU-26m. 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 ruler to adjust the throw of the elevator,
ailerons and rudder. Adjust the position of the
pushrod at the control horn to achieve the
following measurements when moving the sticks
to their endpoints.
Aileron Low Rate
Up 3/4-inch (19mm)
Down 3/4-inch (19mm)
Aileron High Rate
Up 11/4-inch (32mm)
Down 11/4-inch (32mm)
Elevator Low Rate
Up 1-inch (25mm)
Down 1-inch (25mm)
Elevator High Rate
Up 2-inch (50mm)
Down 2-inch (50mm)
Rudder Low Rate
Up 11/2-inch (38mm)
Down 11/2-inch (38mm)
Rudder High Rate
Up 2-inch (50mm)
Down 2-inch (50mm)
Measurements are taken at the inner or
widest point on the control surface.
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 3
from the leading edge of the wing. Mark the location
for the Center of Gravity on the top of the wing next to
the fuselage as shown.
When balancing your model, support the plane
inverted at the marks made on the top of the wing
with your fingers or a commercially available
balancing stand. Adjust components as necessary so
the model hangs level or slightly nose down. This is
the correct balance point for your model. You might
find you may be required to add a small amount of
weight to either the front or back of the fuselage to
achieve the correct balance.
1
/2 to 37/8 inches (89 to 98mm) back
These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.
Travel Adjust, Sub Trim and Dual Rates are
not listed and should be adjusted according
to each individual model and preference.
22 E-flite Sukhoi SU-26m 480 ARF Assembly Manual
After the first flights, the CG position can be adjusted
for your personal preference.
Preflight
Range Test Your Radio
Flying Your Sukhoi SU-26m 480
Check Your Radio
Before going to the field, be sure that your batteries
are fully charged per the instructions included with
your radio. Charge both the transmitter and receiver
pack 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, start 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.
Keep loose items that can get entangled in
the propeller away from the prop. These
include loose clothing, or other objects such
as pencils and screwdrivers. Especially keep
your hands away from the propeller.
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). Test run
the motor and make sure it transitions smoothly from
off to full throttle and back. Also ensure the engine is
installed according to the manufacturer’s instructions,
and it will operate consistently.
1. Before each flying session, be sure to range
check your radio. This is accomplished by turning
on your transmitter with the antenna collapsed.
Turn on the receiver in your airplane. With
your airplane on the ground and the engine
running, you should be able to walk 30 paces
(approximately 100 feet) away from your airplane
and still have complete control of all functions.
If not, don’t attempt to fly! Have your radio
equipment checked out by the manufacturer.
2. Double-check that all controls (aileron, elevator,
rudder and throttle) move in the correct direction.
3. Be sure that your transmitter batteries are
fully charged, per the instructions included with
your radio.
Flying the Sukhoi SU-26m 480 is about as fun as it
can get at the park. A very light wing loading and
extreme control throws make for some exciting 3D
flying. Verify that your CG is at the correct location as
per the manual and that you have your rates set up to
your liking. Verify all control throws are in the correct
direction and the motor spins in the correct direction as
well.
Point the model into the wind and add some throttle
trim until the motor begins to turn. This will be your
flight idle. Now, apply power slowly. You will find the
model will become airborne very quickly and at a low
speed. This model excels at flying slow and easy as
well as fast and extreme. Trim the model for level flight
at half throttle. Only use full throttle for maneuvering.
It is not recommended to fly this model fast or at full
throttle in level flight. Doing this can result in the flight
controls fluttering and a potential catastrophic failure
of the airframe.
You will find you can adjust the CG to your liking by
moving the battery pack fore or aft on the fuselage.
Also keep the battery on the fuselage mounted high (at
least at wing centerline or above) to help in hovering
maneuvers and harriers.
To land the Sukhoi SU-26m 480, just reduce the
throttle to idle and feed in up elevator until the model
settles into a slightly nose high attitude. Gently fly the
model down to the landing spot with a final flair at
touchdown. You will find the model will have a very
short roll out. We hope you enjoy the Sukhoi SU-26m
480 as much as we do.
Happy landings.
Check all the control horns, servo horns, and
clevises to make sure they are secure and in good
condition. Replace any items that would be considered
questionable. Failure of any of these components in
flight would mean the loss of your aircraft.

Sukhoi SU-26m Safe Operating Recommendations
- Inspect your model before every flight to make
certain it is airworthy.
- Be aware of any other radio frequency user who may
present an interference problem.
- Always be courteous and respectful of other users of
your selected flight area.
- Choose an area clear of obstacles and large enough
to safely accommodate your flying activity.
- Make certain this area is clear of friends and
spectators prior to launching your aircraft.
- Be aware of other activities in the vicinity of your
flight path that could cause potential conflict.
- Carefully plan your flight path prior to launch.
- Abide by any and all established AMA National
Model Aircraft Safety Code.
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.
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.
