Bind your transmitter

•

Familiarize yourself with the controls

CHARGING WARNINGS

WARNING: Failure to comply with the following warnings could result in product

malfunction, electrical issues, excessive heat, FIRE, and ultimately injury and
property damage.

 NEVER LEAVE CHARGING BATTERIES UNATTENDED.
 NEVER CHARGE BATTERIES OVERNIGHT.
 Never charge damaged batteries. If the battery begins to swell during charging

or use, discontinue immediately.

 Always use the included battery and charger. Disconnect the battery after

charging.

 Charge batteries away from flammable materials in a well-ventilated area.
 Never charge, transport, or store batteries in hot, cold, or very sunny places

(recommended between 41–104°F or 5–40°C).

Charge the Flight Battery

CAUTION: Only use chargers specifically designed to charge the included Li-Po

battery. Failure to do so could result in fire, causing injury or property damage.

CAUTION: Never exceed the recommended charge rate.

The USB battery charger included with your aircraft has been designed to safely
charge the 1S 3.8V 500mAH 25C Li-Po flight battery.

NOTICE: Inspect the battery to make sure it is not damaged e.g., swollen, bent, broken
or punctured. Charge only batteries that are cool to the touch and are not damaged.

1. Insert the charger into a USB port.

2. Connect the battery to the charger as shown in the illustration (Notice: Keep both
red dots on the same side.) When you make the connection successfully, the
LED on the charger turns solid red, indicating charging has beg un. Charging a
fully discharged (not over-discharged) 500mAH battery takes approximately 60
minutes. The LED turns solid green when the charge is complete.

3. Always disconnect the flight battery from the charger immediately upon
completion of charging.

CAUTION: Once charging is complete, immediately remove the battery.

Never leave a battery connected to the charger.

Installing the Propellers

Refer to the illustration for the proper motor rotation and propeller location.
The propellers are press fit onto the motor shafts. Remove the propellers by pulling the

center hub straight up away from the motor.
Install the propellers by pressing the center hub over the motor shaft, being careful not

to press it too far down on the shaft. The propeller and motor should spin freely when
installed correctly.

Installing the Transmitter Batteries (RTF)

The LED indicator flashes and the
transmitter beeps progressively faster as
the battery voltage drops.

Replace the transmitter batteries when
the transmitter begins to beep.

Install the Flight Battery

CAUTION: Always disconnect the Li-Po battery from the aircraft when not flying

to avoid over-discharging the battery.
