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
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
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
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.

towards the leading edge of the stab. The servo arm needs
to be 1.25 inch; if in case of using a JR aluminum servo
arm, this would be the third outermost hole.
2. Mount the servo screws and back them out.
4. Mount the servo so the output shaft is towards the
leading edge of the stab.
5. Prepare the ball link and pushrod. Attach the ball
link to the control horn using a 2.5mm ball driver and hold
the locknut with help of a vise grip or nut driver.
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
from the center of the arm. Mount the servo arm parallel to
the elevator hinge line. Use threadlock on the center servo
arm screw. Use a 48-inch JR Heavy-Duty extension from
elevator to receiver.

3D Elevator Setup
1. The second servo bay needs to be opened and
control horns and plate need to be glued using 15- to
30-minute epoxy. This step is also very similar to Aileron
Servo Installation in 3D section. Follow the same steps and
make sure to line up the control horn pivot point to the
elevator hinge line.
4. Remove the covering to mount the control horns.
7. Prepare the ball link and pushrod for installation.
5. Mix 30-minute epoxy and fill the control horn slots.
8. Install the ball links at the 1.5-inch hole on the arm.
Use threadlock on the center servo arm screw.
2. Mount the servo screws and back them out. Apply
some CA to harden the wood. This step is the same as steps
2 and 3 in the elevator precision setup section.
3. Mount the servo once the glue is dry.
6. Install the control horns and plate, make sure to
line up the control horns hole and elevator hinge line. Clean
excess epoxy using alcohol swabs.

of masking tape to the bottom of the MatchBox and using CA
glue a piece of hook and loop to the MatchBox.
Note: Refer to MatchBox setup in the wing section.
Rudder Installation
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.
