The Spektrum AR6400 installed on your Sukhoi is a lightweight

combination of main motor electronic speed control, servos and Spektrum

DSM2 compatible receiver. The receiver unit is also equipped with a status

indicator LED. Please refer to the instruction manual of the AR6400 for more

information on the unique features and programming options.

The following checklist contains the steps you must follow to ensure proper

arming and operation of the receiver unit, as well as proper motor response:

• Each time before you fly you should ALWAYS turn the transmitter on

before connecting the flight battery to the receiver unit. Never connect

the flight battery to the receiver unit before powering the transmitter on

first. After each flight, be sure that you always disconnect the flight bat-

tery from the receiver unit before powering the transmitter off.

Note: The only time you should connect the flight battery to the receiver

unit before powering the transmitter on is when you are binding

the receiver of the receiver unit to the transmitter. Please see the

Transmitter and Receiver Binding section of this manual for more

information.

• 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, aileron and elevator trims.

• When the status LED on the AR6400 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

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 of the AR6400 does not become solid red, please

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 to be sure 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.

Receiver Control Unit Description, Arming

and Motor Control Test

With the rudder stick pushed to the left, the rudder should move to the left (if

viewed from behind the airplane).

If at any time during the test the controls respond in the opposite direction, it

may be necessary to reverse/change the direction of operation of the flight

controls. Follow your transmitter instructions to change the direction of the

various flight controls.

Once you’ve reconfirmed the flight control directions, all controls should be

functioning properly. However, if you continue to encounter any problems with

your Sukhoi responding properly to the transmitter, do not fly. Call the Horizon

Support Team at 1-877-504-0233.

Note: ParkZone recommends setting Dual rates at 70% for first

flights. Dual rates and expo (if available) can then be tuned

to the pilots tastes.
