Installing the Flight Battery

CAUTION: Always disconnect the Li-Po battery from the quadcopter when not ﬂ ying to avoid over-discharging the

battery. Batteries discharged to a voltage lower than the lowest approved voltage may become damaged, resulting

in loss of performance and potential ﬁ re when batteries are charged.

To bind or re-bind your quadcopter to your chosen transmitter, follow the directions below.

Transmitter and Receiver Binding

If you encounter problems, obey binding instructions and refer to the

troubleshooting guide for other instructions.

If needed, contact the appropriate Horizon Product Support ofﬁ ce. For a

list of compatible DSM

transmitters, please visit www.bindnﬂ y.com.

Failsafe

The included receiver does not have failsafe capabilities. Failsafe is detected at the ﬂ ight controller. In the event of a loss of signal

to the receiver the ﬂ ight controller will cut power to the motors to prevent a ﬂ y-away situation.

1. Set the motor arm switch to OFF

(position 1).

2. Lower the throttle.

3. Power on the transmitter.

4. Attach hook material to the quadcopter frame and loop

material to the battery.

5. Install the ﬂ ight battery on the quadcopter frame and

secure it with the hook and loop strap.

6. Connect the battery cable to the aircraft power lead,

noting correct polarity. Do not move the quadcopter until

the receiver initializes.

CAUTION: Connecting the battery to the aircraft

power lead with reversed polarity will cause dam-

age to the power distribution board, ESCs and the battery.

Damage caused by incorrectly connecting the battery is

not covered under warranty.

7. The quadcopter motors will emit initialization tones,

indicating the ESC is armed.
