Transmitter and Receiver Binding

Binding is the process of programming the control unit to recognize the GUID

(Globally Unique Identiﬁ er) code of a single speciﬁ c transmitter.

The aircraft should be bound to the transmitter at the factory, but if you need to

re-bind them, follow these steps. If your aircraft does not respond to the transmitter

when the batteries in the aircraft and transmitter are fully charged, your aircraft

and transmitter may need to be re-bound using the instructions below.

Please refer to the optional parts list in this manual or visit www.bindnﬂ y.com for a

list of compatible transmitters. For the BNF aircraft, you need to ‘bind’ your chosen

Spektrum™ DSMX

technology equipped aircraft transmitter to the receiver for

proper operation.

IMPORTANT: The throttle will not arm if the transmitter’s throttle control is not put

at the lowest position. If you encounter problems, follow the binding instructions

and refer to the transmitter troubleshooting guide for other instructions. If needed,

contact the appropriate Horizon Product Support ofﬁ ce.



Binding Procedure (without GPS Module)

1. Make sure the transmitter is

powered off.

2. Make sure the transmitter controls

are neutral, the throttle is in the

low position, and the aircraft is

immobile.

3. Connect the ﬂ ight battery in the

aircraft, then power on the ESC

switch. The Flight Controller LED will

begin to ﬂ ash red and blue.

4. On the remote Spektrum receiver

that is connected to the ﬂ ight

controller, press and release the

bind button. The receiver LED will

ﬂ ash rapidly.

5. Press and hold the trainer button

on the top of the transmitter while

turning on the power switch.

6. When the receiver binds to the

transmitter, the receiver LED will

be solid on. Flight controller LED in

windshield will also be green when

in beginner mode. (without LAS or

GPS installed)

Once bound the receiver and transmitter

should retain their bind for future ﬂ ights.

IMPORTANT: IF THE OPTIONAL GPS MODULE IS INSTALLED the aircraft will not respond to transmitter commands after binding if it cannot acquire a GPS

signal.

Binding: After binding with the GPS module installed, the aircraft will search for a GPS lock, indicated by the elevator slowly cycling up and down. After

acquiring a GPS lock, all ﬂ ight controls will respond normally except throttle. The throttle will be limited, allowing the aircraft to be taxied out to takeoff

position on the runway. Set the home position to regain full functioning throttle. See the Powering On With GPS section of this manual for further details.

Compass calibration: After binding the ﬁ rst time with the GPS module installed in the aircraft, compass calibration is required. The aircraft will automatically

enter the compass calibration sequence after installing the GPS for the ﬁ rst time. This is indicated by the ailerons slowly cycling up and down. The aircraft will

not respond to transmitter commands with the GPS module installed until calibration has been completed. See the Compass Calibration section of this manual

for further details.

Subsequent binding with the GPS module will not require compass calibration.

Applies only when the optional GPS module is installed
