Takeoff
When you are prepared to fly, start the motors by moving both sticks to the bottom inside corners, then back to center.
Increase the throttle until the model is approximately 2 ft. (600mm) off the ground and check the trim so the model flies
as desired. Once the trim is adjusted, begin flying the model.
Typical flight times for the included battery range from 5–7 minutes.
Low Voltage Cutoff (LVC)
LVC decreases the power to the motors when the battery voltage gets low. When the motor power decreases and the
LEDs blink, land the aircraft immediately and recharge the flight battery.
LVC does not prevent the battery from over-discharge during storage.
NOTICE:
Repeated flying to LVC will damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level hover. After landing, activate the throttle cut feature to shut off
the motors; disconnect and remove the battery from the aircraft after use to prevent over discharge. During storage,
make sure the battery charge does not fall below 3V per cell.

Installing the Propellers
Ensure your propellers and hubs are correctly installed. Install “A”
props counterclockwise on Motor Pods 1 and 2. Install “B” props
clockwise on Motor Pods 3 and 4.
Caring for the Video Transmitter Antenna
If your video transmitter antenna gets bent or flattened as a
consequence of a hard landing, bend the antenna so the lobes are at
a 45° angle to the bottom plane of the antenna, as shown at the right.
NOTICE: A bent or broken antenna will adversely affect
camera use.

Post-Flight Inspection and Maintenance Checklist
√
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush
or a dry, lint-free cloth.
Motors Replace the motor when the model will not fly steady or veers off when doing a climb out.
Wiring
Make sure the wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal
screws in plastic parts. Tighten screws so the parts are mated together, then turn the screw only
1/8th of a turn more. Do not use threadlock on or near plastic parts.
Propellers
Make sure there is no damage to the propellers or other parts that move at high speed. Damage to
these parts includes cracks, burrs, chips or scratches. Replace damaged parts before flying.
