  Step 1

Attach a 24-inch (610mm) servo extension to the aileron 

servo. Secure the extension using a commercially 

available connector, heat shrink tubing or string so it will 

not unplug inside the wing.

  Step 2

Tie a weight to a piece of string. Lower the weight into the 

opening for the aileron servo.

  Step 3

Tip the wing so the root is facing down and lower the 

weight through the wing.

  Step 4

Tie the string to the servo extension.

  Step 5

Use the string to pull the extension through the wing. Tape 

the extension so it will not fall back into the wing.

  Step 6

Secure the servo using the hardware provided with 

the servo. The output of the servo faces the trailing 

edge. Make sure to harden the holes for the servo 

mounting screws using thin CA to prevent them from 

vibrating loose.

  Step 7

Thread the control horn onto the control horn screw so the 

bottom of the horn is 25/32 inch (20mm) from the surface 

of the aileron.

  Step 8

Plug the aileron servo into the receiver. Center the aileron 

trim and stick to center the aileron servo. Also make sure 

any sub-trims have been set to zero in the radio memory. 

Check the operation of the servo at this time.
10

  Step 9

Attach the ball end to the top side of the servo arm 

using the ball end hardware, including the cone washer 

between the servo arm and ball end. The hole used will 

be 1 1

/

4

-inch (32mm) from the center of the servo arm.

  Step 10

With the servo at the neutral position and radio on, attach 

the servo arm to the servo. Place it on the spline that sets 

the arm closest to parallel with the hinge line. (This will be 

fine-tuned later.) Turn off the receiver and manually turn 

the arm so it is parallel with the hinge line.

  Step 11

Temporarily remove the setscrew from the control horn 

and remove the clevis. Thread the clevis onto the 3-inch 

(76mm) linkage and adjust the length to center the aileron. 

Remember to keep the aileron servo arm parallel to the 

hinge line while adjusting the linkage. Reinstall the set 

screw to attach the clevis to the control horn.

Note: A small amount of threadlock is 

recommended to keep the set-screw secure.

  Step 12

Turn on the radio and adjust the sub-trim in the 

transmitter until the aileron is at the neutral position. 

Deflect the stick to full right aileron and adjust the travel 

adjust so the deflection is 40 degrees. Repeat this for full 

left deflection and adjust for 40 degrees.

 Step 13

Repeat steps 1 through 12 for the remaining wing panel.

-inch Single Side Alum Adj. Spline Servo Arm

Note: When using a servo with less than 

300 oz/in of torque, it is highly recommended 

to use two rudder servos and link them 

together using a JR MatchBoxTM. An additional 

servo location on the opposite side of the 

fuselage will require the removal of the 

covering to install your second servo.

 Step 1

Attach a 36-inch (915mm) servo extension to the rudder 

servo. Secure the extension using a commercially 

available connector, heat shrink tubing or string so it will 

not unplug inside the fuselage.

 Step 2

Assemble the rudder linkage using a 4 1

/

2

-inch (114mm) 

linkage, ball end and control horn. The control horn is 

then threaded on the control horn screw so the bottom of 

the horn is 5/8-inch (16mm) from the control surface.

 Step 3

Attach the rudder to the fin/fuselage using the hinge pin 

located in the hinges.

Hint: Use a drill to aid in installing 

the hinge wire. This will help guide the 

wire through each of the hinges

Note: The tail gear will keep the rudder 

hinge in position. You will need to trim the 

removable hinge pin so it is 1/4-inch (4mm) 

above the tail gear when it has been installed.

 Step 4

Attach the ball end to the servo horn using the hardware 

provided with the ball end. The attachment point will be 

1 1

/

2

-inch (38mm) from the center of the servo horn. 

When installing the ball end, make sure to place the 

supplied cone washer between the ball end and servo arm.

 Step 5

Position the tail gear assembly on the bottom of the 

fuselage. Use a felt-tipped pen to mark the locations for 

the two screws. The forward hole is 3 inches (76mm) 

forward of the rudder hinge pin.

 Step 6

Drill each of the locations using a drill and 3/32-inch 

(2.5mm) drill bit.

 Step 7

Thread a #6 x 3/4-inch socket head sheet metal screw into 

the holes, then remove the screw.
15

 Step 8

Apply a few drops of thin CA into each of the two holes to 

harden the wood. This will help in preventing the screws 

from vibrating loose.

 Step 9

Follow Steps 5 through 8 to attach the tiller arm to the 

bottom of the rudder with two #4 x 1/2-inch socket head

Installing the MTW 110 Canister and Header 

(Available from Desert Aircraft)

 Step A

Use a felt-tipped pen to draw lines vertically that connect 

the bottom of the fuselage to the sides of the opening.

 Step B

Use a rotary tool and cut-off wheel to cut the former along 

the lines made in the previous step.

 Step C

Carefully remove the section from the fuselage.

 Step D

Use a hobby knife to trim the covering 1/8-inch (3mm) 

away from the edges of the opening. The excess material 

will be sealed back into position to fuel-proof the area and 

make a clean installation of the opening.
26

 Step E

You may want to save the covering in case it is needed 

for small repairs.

 Step F

Use a covering iron to seal the edges of the covering 

inside the fuselage.
27

 Step G

Remove the covering from the bottom of the fuselage and 

cut the stringers as shown. Repeat Steps D through F to 

seal the covering around the opening. This is necessary to 

allow cooling air to pass through the fuselage to cool the 

canister muffler.

 Step H

Remove the material from the cowling to clear the exhaust 

system and to provide cooling air to pass over the engine.
28

 Step 2

Mount radio switch (or switches) in the rear switch holes 

and the ignition switch in one of the front switch holes.

Note: There are three switches on the plane. 

The ignition is right behind the firewall and 

the other two are above the receiver. We used 

dual batteries so there are two switches for 

the radio system. We plugged one switch 

into the battery port on the receiver then used 

a Y-harness off of any other channel and 

plugged the other switch into the Y-harness. 

Required Parts

• Fuselage assembly • Receiver

• Receiver battery • Foam

• Tie wraps

Required Tools and Adhesives

• Hobby knife • Y-harness

 Step 1

Mount the radio system inside the fuselage. Make sure 

the radio is protected from vibrations from the fuselage by 

using foam at any contact points between the radio system

Canopy Installation

Required Parts

• Fuselage assembly • Pilot bust

• Canopy

Required Tools and Adhesives

• Canopy glue • Felt-tipped pen

• Painter's tape • Waxed paper

• 30-minute epoxy • Sandpaper

• Rubbing alcohol • Paper towel

 Step 1

Be sure the visor screws are tight. It is recommended to 

remove the screws and use a drop of threadlock on them 

to prevent vibrations from causing them to vibrate loose.

 Step 2

Use 30-minute epoxy to secure the pilot bust to the 

canopy hatch.

 Step 3

Trim the instrument panel from the decal sheet. Apply the 

decal in position in the cockpit.

 Step 4

Position the canopy onto the hatch. Use a felt-tipped pen 

to trace the outline of the canopy onto the hatch.
30

Radio Setup

A 7-channel or greater computer radio is highly 

recommended. This allows the following features:

• Mixing the right aileron to the left aileron (flaperon mix)

• Electronically adjustable aileron differential

• Mixing the right elevator to the left elevator (dual 

elevator mixing)

• Independent travel and trim adjustments for each 

elevator half

When using a 7-channel or greater computer radio, 

each servo is plugged into its own separate channel. 

Consult your radio manual for specific details on 

hookup and programming.

 Step 5

Sand the hatch and canopy where they contact each other 

using sandpaper. Clean the area using rubbing alcohol 

and a paper towel.

 Step 6

Slip a piece of waxed paper between the hatch and 

fuselage and install the canopy hatch onto the fuselage 

and bolt in place. Use canopy glue to attach the canopy to 

the canopy hatch. Use painter's tape to keep the canopy in 

position until the glue fully cures.
31

Setting the control throws for your Sukhoi does require 

some attention to detail. To correctly set the throws, it 

is highly suggested to use the following procedure to 

achieve the greatest mechanical advantage from your 

servos.

 Step 1

Determine the maximum amount of control surface throw 

from the throws listed. Use the high rate throws listed 

to set the maximum amount of throw, then use your 

computer radio for the lower rate listed.

 Step 2

Set the Travel Adjust (ATV on a Futaba transmitter) to 

about 15% under the max. (On a JR transmitter, that 

is 135%.) Make sure to set both directions during this 

process.

 Step 3

Adjust the position of the clevis on the control horn and 

position of the ball link on the servo arm to achieve the 

throw decided in Step 1. It is highly recommended not to 

change the position on the servo arm unless absolutely 

necessary. Use Travel Adjust (ATV) to finalize the throws. 

That is why we left a little margin in the percentages back 

in Step 2.

 Step 4

If setting a dual elevator or aileron, match the linkage 

locations used back in Step 3. Increase or decrease the 

Travel Adjust (ATV) a few points as necessary to fine-tune 

the throws to match up left and right sides and up and 

down throws so all is symmetrical.

This is all necessary to tune the mechanical advantage as 

good as possible. When setting up a model for 3D, the 

mechanical advantage will be less because of the large 

throws, and thus the servo will work harder and wear 

faster. Using an insufficient servo for the job, or trying 

to get too much throw, will cause something to give, 

probably the servo.

There isn’t an exact geometry to the linkage, as it depends 

on how much throw each individual modeler requires. 

The linkage geometry should always be maximized so the 

servo isn’t working any harder than it has to.

Aileron:

High Rate: 40 Degrees up, 55% Exponential

40 Degrees down, 55% Exponential

Low Rate: 21 Degrees up, 40% Exponential

21 Degrees down, 40% Exponential

Elevator:

High Rate: 42 Degrees up, 75% Exponential

42 Degrees down, 75% Exponential

Low Rate: 10.5 Degrees up, 45% Exponential

10.5 Degrees down, 45% Exponential

Rudder:

High Rate: 39 Degrees left, 50% Exponential

39 Degrees right, 50% Exponential

Low Rate: 23 Degrees left, 40% Exponential

23 Degrees right, 40% Exponential

Control Throws

Rates and Expos

Use Expo to soften the feel of the model. On high 3D 

rates, use quite a bit of expo. The goal on 3D rates is to 

get the model to feel the same around neutral as it does 

on low rates.

Use low rate settings for all flying except for 3D 

aerobatics. For precision flying or general sport hotdogging, the low rate throws are perfect, even for snap 

rolls. The only exception is rudder rates. Use 3D rudder 

rate when doing stall turns and rolling circles, since 

the more rudder the better for these. When doing 3D 

aerobatics, flip to 3D rates just before the maneuver. As 

soon as the maneuver is done, flip back down to low rate 

to avoid over-controlling the model.
32

An important part of preparing the aircraft for flight is 

properly balancing the model. This is especially important 

when various engines are mounted.

Caution: Do not inadvertently skip this step!

The recommended Center of Gravity (CG) location for 

your model is: 7 5

/

8

 to 8 inches (194 to 203mm) back 

from leading edge of wing at the wing root. Mark the 

location of the CG onto the bottom of the wing using 

a felt-tipped pen. With a helper, lift the aircraft with your 

index finger at the location marked on the wing. Make 

sure the aircraft is upright when checking the CG. If the 

nose of your aircraft hangs low, add weight to the rear of 

the aircraft. If the tail hangs low, add weight to the nose 

of the aircraft. Stick-on weights are available at your local 

hobby store and work well for this purpose.

Recommended Center of Gravity (CG)

A computer radio will allow you to do quite a bit of 

fine-tuning to the feel of the Sukhoi, which will make 

aerobatics even easier.

Preflight

For those of you who are veterans of large models, this 

is old news. But to you newcomers to the world of large 

models, this is very important information.

While many smaller models are not critical of proper 

battery use, and are tolerant of improper control linkage 

setups and flying techniques, large models are not. Don’t 

let that scare you away from large models; they are truly 

one of the best flying experiences in RC that money 

can buy. However, please pay particular attention to the 

following areas.

Maintain the proper mechanical advantage on all 

control surface linkages.

Just as with unsealed hinge gaps, mechanical advantage 

is often another cause of flutter. Please follow the control 

horn and servo arm lengths recommended in this manual. 

Shorter arms on the servo or longer control horns on the 

elevator and ailerons are fine, but do not try to go the 

other way to increase throw. It can cause flutter or servo 

failure on the Sukhoi. The recommended linkage setups 

are more than adequate to achieve full 3D throws.

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 engine and make sure it transitions smoothly 

from idle to full throttle and back. Also ensure the 

engine is tuned according to the manufacturer’s 

instructions, and it will run consistently and constantly 

at full throttle when adjusted.

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.

Never attempt to make full throttle dives!

Large models perform much more like full-size aircraft 

than small models. If the airframe goes too fast, such as 

in a high throttle dive, it may fail. The Sukhoi should be 

flown like a full-scale Sukhoi. Throttle management is 

absolutely necessary.

Hardware checks

Double-check the setscrews in all contol horns to be sure 

they are very tight. Periodically check these to be sure 

they have not loosened over time. Always use threadlock 

on metal-to-metal fasteners.

Receiver Battery Selection

Be sure adequate batteries are used to power the receiver. 

It is STRONGLY recommended that two identical 6-volt 

receiver packs are used. Each pack must have a minimum 

of 2700mAh capacity. Use packs of 3000mAh when super 

high torque servos are used.

Servo selection

Be sure all servos used on elevator, aileron and rudder are 

metal geared type and have at least 188 oz/in of torque. 

Failure to do this will very likely result in a failure and 

loss of the model.

Range check

Always range check the radio system per the 

manufacturer's instructions before the initial test flight 

and periodically afterward. 

Check the voltage of the on-board packs

ALWAYS use an ESV with a 1-amp load to check the 

receiver battery packs and the ignition pack before each 

and every flight. If there is any doubt that the packs are 

questionable, DO NOT FLY until the packs are recharged.
