Flight Mode Selection

Change flight modes by pressing different buttons on the transmitter. The quadcopter is in stability mode when first powered on. The active flight mode is indicated by the LEDs at the bottom of the quadcopter.

• Agility mode: The quadcopter has no bank angle limits and will not return to level flight if the sticks are released. Use rates and expo to tune the performance according to your flying style.
• Stability mode: The bank angle is limited. When the sticks are released, the quadcopter will return to level flight.
• Altitude mode: Maintains altitude. Before changing to altitude mode, please make sure the aircraft remains steady. The bank angle is limited. When the sticks are released, the quadcopter will return to level flight.
• Quick Invert: Won't respond when throttle too low or battery voltage too low.
• Quick Return: Keep throttle lowest.

Fly the Quadcopter

Takeoff

Arm the motors by pressing the arming switch. Increase the throttle until the model is approximately 2ft (600mm) off the ground in a low-level hover and concentrate on balancing the throttle stick's position so that the quadcopter holds a steady hover altitude. In some cases, you may need to make a few short “hops” to an altitude of just a few inches until you become familiar with the control inputs and trim settings required to maintain a steady hover and altitude.

Hovering

The quadcopter requires minor throttle adjustments to maintain its altitude in hover. Remember to keep these throttle adjustments as minimal as possible. Large adjustments could result in a loss of control or a possible crash.

While attempting to establish a low-level hover, check to see if any trim adjustments are required to keep the quadcopter from drifting in various directions. If you find that it constantly drifts without any directional control input, land the model before making any adjustments to the trim settings.

• If the nose of the quadcopter rotates to the left or right, adjust the rudder trim in the opposite direction.
• If the quadcopter continually drifts forward or backward, adjust the elevator trim in the opposite direction.
• If the quadcopter continually drifts to the left or right, adjust the aileron trim in the opposite direction.

Continue making minor trim adjustments until the machine hovers at a low altitude with very little drifting and directional control input. If this is your first multicopter or helicopter, seek the help of an experienced pilot to trim the model for you before making your first flight.

With your quadcopter properly trimmed and maintaining a stable low-level hover, practice using the rudder, elevator, and aileron controls to familiarize yourself with the machine's responses to control inputs. Remember to keep the control inputs as minimal as possible.

Average flight times are approximately 6 minutes.

Landing

To land the quadcopter, establish a low level hover. Slowly lower the throttle until the quadcopter touches down.

After landing, press the arming button to disarm the motors. Unplug and remove the flight battery.

To prevent excessive wear to the motors, always allow the motors to cool between flights.

NOTICE: Crash damage is not covered under warranty.

Low Voltage Cutoff (LVC)

Once the battery reaches 3V under load, the ESC will continuously lower power supplied to the motor until complete shutdown occurs. This helps prevent over-discharge of the Li-Po battery. Land immediately once the ESC activates LVC. Continuing to fly after LVC can damage the battery, cause a crash, or both. Crash damage and batteries damaged due to over-discharge are not covered under warranty.

Repeatedly flying the aircraft until LVC activates will damage the flight battery. Disconnect and remove the Li-Po battery from the aircraft after use to prevent trickle discharge. During storage, make sure the battery charge does not fall below 3V per cell.

Battery Level Indicator

When first powered on, the quadcopter indicates the charge level of the flight battery by lighting the LED at the top of the quadcopter briefly.

FPV Camera and Video Transmitter

NOTICE: Consult local laws and ordinances before operating FPV (first person view) equipment. In some areas, FPV operation may be limited or prohibited. You are responsible for operating this product in a legal and responsible manner.

NOTICE: The 25mW micro video transmitter range on your quadcopter is less than your flight control transmitter range. Ensure you have adequate video camera range for filming.

Tips: If you are flying with an FPV headset and are prone to motion sickness, sit in a chair. If you start to suffer from motion sickness while flying, lower your chin against your chest.

Fly in open areas, away from people, trees, cars, and buildings. The range of the system can be impacted by any obstructions blocking your signal. It is normal to see break up in the video going behind trees and other obstacles.
