Installing the Flight Battery

1
1. Lower the throttle to the lowest setting.
2. Power on the transmitter.
3. Install the battery in the helicopter by sliding it into the battery mounting supports/slots between the main landing gear. Slide the battery into the
slots with the label facing downward and the connector oriented toward the back of the helicopter.
4. Connect the battery cable to the 3-in-1 control unit power connector.
NOTICE: Set the helicopter down and do not allow it to move until the red LED on the helicopter turns green and stops blinking (remains solid.).
CAUTION: Always disconnect the Li-Po battery from the aircraft control unit 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.

Protecting Your Flight Battery

The circuit board in the helicopter includes a protection circuit for your fl ight battery. LVC (Low Voltage Cutoff) ensures the battery is discharged to
within a safe limit for operation.
Once you realize that power is dropping off in fl ight, please land the helicopter.
LVC is activated when the Red LED on the circuit board starts fl ashing again, late in the fl ight.
CAUTION: Do not continue to fl y the helicopter while LVC is active or damage to the battery may result.

Transmitter and Receiver Binding

The CX4 uses Spektrum 2.4 GHz DSM technology and comes from the factory with the binding procedure complete. Binding teaches the receiver the
specifi c code of the transmitter so it will only communicate with your transmitter. There should be no need to bind the transmitter and receiver prior to
use. If you ever need to re-bind the transmitter and receiver, please follow the steps below.
Each time you power the transmitter on, it will enter Bind Mode for a few seconds, as indicated by the red blinking LED located under the door on the
front of the transmitter in the bottom left hand corner of the transmitter. Once this LED becomes solid, the transmitter is no longer in bind mode.
