Transmitter And Receiver Binding; 5-In-1 Control Unit Function Description - Horizon Hobby Blade 120 SR Manuel D'utilisation

Transmitter and Receiver Binding

If you purchased an RTF model, the transmitter is bound to the model at the factory.
To bind or re-bind your 120 SR to your chosen transmitter please follow the directions below:
Binding is the process of programming the receiver of the control unit to recognize the GUID (Globally Unique
Identifier) code of a single specific transmitter. You need to 'bind' your chosen Spektrum
equipped aircraft transmitter to the receiver for proper operation.
 Binding Procedure Reference Table
1. Refer to your transmitter's unique instructions for binding to a receiver.
2. Make sure the flight battery is disconnected from the helicopter.
3. Power off the Blade MLP4DSM or your chosen transmitter.
4. Connect the flight battery in the helicopter. The 5-in-1 unit LED will begin to
flash. (Typically after 5 seconds).
5. Put your transmitter into bind mode. If using the Blade MLP4DSM
transmitter, push the left control stick vertically into the case until it clicks,
while powering on the transmitter.
6. Make sure transmitter controls are neutral and throttle is in low position.
7. The 5-in-1 unit status LED light will go from a flashing to a solid light. After
5 to 10 seconds the light will become solid indicating the receiver is bound
to the transmitter. Note: If the LED does not go to a solid light, refer to
Troubleshooting Guide at back of manual.
Additional Binding Information
Prior to each flight, power on your transmitter and wait about five seconds before you plug the flight battery into the
receiver. This allows time for the transmitter to scan and secure two open frequencies. If you plug the flight
battery in too quickly and miss the link, the receiver may inadvertently enter bind mode. If this occurs leave the
transmitter on, then disconnect and reconnect the flight battery.
Please avoid binding near large metal objects (furniture, vehicles, etc.), and binding with the transmitter too near
the aircraft. Please bind with transmitter at least 50cm (2 feet) from aircraft.

5-in-1 Control Unit Function Description

The unique Control Unit installed on your 120 SR is a lightweight combination of main motor electronic speed
controls, mixer, gyro, servos and Spektrum DSM2 compatible receiver. The 5-in-1 unit is also equipped with a
status indicator LED.
The following text describes how to make sure of arming, control unit operation and motor control:
Before each flight, ALWAYS power on the
❏
transmitter before connecting the flight battery to
the 5-in-1 unit. After each flight keep control of
the helicopter by disconnecting the flight battery
from the 5-in-1 unit before powering off the
transmitter.
Note: Installing the flight battery before powering
on the transmitter can start the Binding
process. Please see the Transmitter and
Receiver Binding section of this manual for
more information.
The 5-in-1 unit will arm motors when the throttle
❏
stick is in the lowest possible position, and the
throttle trim is also at the middle or a lower than
middle position (the middle position is indicated
by a longer than usual beep/tone). If this is the
first test flight, or a test flight following repairs,
also center the rudder, aileron and elevator trims.

With the transmitter turned on and the transmitter
LED glowing solid RED, it is safe to connect the
flight battery to the 5-in-1 unit.
Connect the flight battery to the 5-in-1 unit.
After the flight battery is connected, the 5-in-1
unit status LED should glow solid RED within a
few seconds.
Note: DO NOT move, sway or pretend to fly the
helicopter after connecting the flight battery.
This movement can stop unit initialization
and gyroscope calibration. If the helicopter
is moved before the 5-in-1 unit status LED
glows solid RED, disconnect then connect
the flight battery to the 5-in-1 unit.
When the 5-in-1 unit status LED glows solid RED,
the control unit is initialized and ready for flight.
Also, as long as you set the throttle stick and trim
to the correct positions during the initialization
