Note: T he only time you should connect the flight battery to

the receiver unit before powering the transmitter is

when binding the receiver to the transmitter. Please

see the Transmitter and Receiver Binding

section of this manual for more information.

The following checklist contains the steps to ensure proper arming

and operation of the receiver unit, as well as the proper motor

response.

The throttle stick MUST be set in the lowest possible position,

•

and for most transmitters, the throttle trim must also be set to

the lowest possible position in order for the receiver unit

to arm. If this is the first test flight, or a test flight following

repairs, you should also center the rudder, elevator, and

aileron trims.
When the status LED on the receiver becomes solid red, the

•

receiver unit is initialized and ready for flight. Also, as long as

you had the throttle stick in the idle position and the throttle

trim in the lowest possible position during the initialization

process, the ESC/motor will now be armed. Use caution as

the propeller will now spin with throttle stick input.
Note: If the status LED on the receiver does not become solid

red, review the following.

If after blinking red the status LED becomes solid red, but you

•

have no control of the motor, you have a positive Radio

Frequency (RF) link between the transmitter and receiver,

but the throttle stick and throttle trim may not be set to the

correct positions. Check that the throttle stick is in the lowest

possible position, and that the throttle trim is set to the middle

or a lower-than-the-middle position. If you now have control of

the motor proceed to the next step of the checklist.

If the blinking red status LED keeps flashing, you do not have a

positive RF link between the transmitter and receiver. Check to

be sure the transmitter has been powered on. If the

transmitter is powered on and functioning properly, disconnect

the flight battery from the receiver unit, then reconnect it. Now

the receiver unit should initialize and arm properly.
Note: In the event you inadvertently enter Bind Mode, the LED

on the receiver will flash red continuously. If this occurs,

cycle the flight battery while the transmitter is on (if

previously bound). If your receiver will not initialize and

arm after following the guidelines listed above, then

rebind the receiver.

Once you place the airplane in a safe area, free of obstructions,

and are clear of the propeller, you can safely begin to power up the

model for proper operation of the motor.

Advance the throttle stick upward slowly, just until the propeller

•

begins to spin, DO NOT attempt to fly the airplane at this time.

Note the direction the propeller spins. If viewed from the front

of the airplane, the propeller will spin counterclockwise. If it is

spinning backwards, disconnect the battery and reverse the

polarity of the motor’s input power leads.

Flying Checklist

Always turn the transmitter on first.

❏

Plug the flight battery into the lead from the receiver.

❏

Allow the receiver to initialize and arm properly.

❏

Fly the model.

❏

Land the model.

❏

Unplug the flight battery from the receiver.

❏

Always turn the transmitter off last.

Choosing a Flying Area

When you are ready for your first flight, select a relatively open

area. Choose an area free of people and obstructions with calm

wind (up to 8 mph). Once you have properly trimmed your airplane

and become comfortable with its capabilities, you will be able to fly

in smaller, less open areas. The Sukhoi SU-26

can also be flown

indoors, in an area the size of a basketball court or larger.

Flying the Sukhoi SU-26

Use low rate control settings on the first flight, and

become familiar with the capabilities before increasing the

control throw.
Place the Sukhoi SU-26

in position for takeoff (facing into the

wind if flying outdoors). Gradually increase the throttle setting to ¾

to full and steer with the rudder. Pull back gently with the elevator

and climb to check trim. Once the plane is trimmed, you can begin

exploring the flight capabilities of the Sukhoi SU-26

IN THE UNFORTUNATE EVENT OF A CRASH OR PROPELLER

STRIKE, NO MATTER HOW MINOR OR MAJOR, YOU MUST LOWER

THE THROTTLE STICK AND TRIM TO THEIR LOWEST POSSIBLE

POSITIONS AS QUICKLY AS POSSIBLE TO PREVENT

DAMAGE TO THE ESC OR THE RECEIVER UNIT.
Failure to lower the throttle stick and trim to the lowest possible

positions in the event of a crash could result in damage to the

ESC in the receiver unit, which may require replacement of the

receiver unit.

Note: Crash damage is not covered under the warranty.
