Charging Warnings

The Battery Charger included with your quadcopter has been designed to safely charge the Li-Po battery.

CAUTION: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result in a fire, personal injury and/or property damage.

• By handling, charging or using the included Li-Po battery, you assume all risks associated with lithium batteries.
• If at any time the battery begins to balloon or swell, discontinue use immediately. If charging or discharging, discontinue and disconnect. Continuing to use, charge or discharge a battery that is ballooning or swelling can result in fire.
• Always store the battery at room temperature in a dry area for best results.
• Always transport or temporarily store the battery in a temperature range of 40-120°F (5-49°C). Do not store battery or model in a car as it may be damaged or even catch fire.
• Always charge batteries away from flammable materials.
• Always inspect the battery before charging.
• Always disconnect the battery after charging, and let the charger cool between charges.
• Always constantly monitor the temperature of the battery pack while charging.
• ONLY USE A CHARGER SPECIFICALLY DESIGNED TO CHARGE LI-PO BATTERIES. Failure to charge the battery with a compatible charger may cause a fire resulting in personal injury and/or property damage.
• Never discharge Li-Po cells to below 3V under load.
• Never cover warning labels with hook and loop strips.
• Never leave charging batteries unattended.
• Never charge batteries outside recommended levels.
• Never charge damaged batteries.
• Never attempt to dismantle or alter the charger.
• Never allow minors to charge battery packs.
• Never charge batteries in extremely hot or cold places (recommended between 40-120°F or 5-49°C) or place in direct sunlight.

Battery Charging

NOTICE: Charge only batteries that are cool to the touch and are not damaged. Look at the battery to make sure it is not damaged.

1. Connect the AC power supply to the battery balance lead.
2. Connect the battery to the balance lead charger adapter.
3. Battery charging is complete when the charger LED is solid green.
4. Always disconnect the flight battery from the charger immediately upon completion of charging.

Charging a fully discharged (not over-discharged) 1200mAh battery takes approximately 90 minutes.

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.

Diagram Description: An illustration showing the battery, charger, and AC power adapter connected.

LED Indications for the charger

• Green LED with power connected but without battery: Standby
• Red LED: Battery connected
• Solid Green LED: Full charge

CAUTION: Once charging is complete, immediately remove the battery. Never leave a battery connected to the charger.

Installing the Flight Battery

1. Remove the battery cover and install the battery in the quadcopter.
2. Connect the battery cable to the control unit and replace the battery cover.
3. Place the quadcopter on its landing gear on a flat surface.

CAUTION: Always disconnect the Li-Po battery from the aircraft when not flying 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 fire when batteries are charged.

Diagram Description: Two images showing the process of installing the flight battery into the quadcopter.

Flight Mode and Rate Selection

• Mode one: default steering and rudder are 10% it is slow speed mode
• Mode two: comfortable flight steering and rudder are 25% it is middle speed mode
• Mode three: fast flight steering and rudder are 45% it is fast speed mode

CAUTION: Fast speed mode is not suitable for beginners.

Flying the X1

Takeoff

1. When you are prepared to fly, put the airplane horizontally on the floor, switch on power.
2. Then you can hear three voices and LED lights on the airplane are flashing.
3. Close the battery cover.
4. Open the transmitter power.
5. You can hear DIDI voice, LED lights on the airplane are flashing rapidly meanwhile four pieces motors make didi voice and LED lights turn on which means matching code is finished.

Unlock the transmitter

When you hear DIDI voice which means unlock is finished.

CAUTION: After unlock is finished, the airplane will be automatically locked if you do not start idling. It needs unlock again to fly.

Diagram Description: Illustrations showing the transmitter controls for Throttle and Aileron during the 'Unlock Signal' phase.

Start idling

Do not move direction stick, pull the throttle stick to the lowest, turn right then turn left finally turn right, you can hear DIDIDI voice from controller, 4pcs blades begin to rotate slowly which means the airplane is on idling and ready for fly.

Diagram Description: Illustrations showing the transmitter controls for Throttle and Aileron during the 'Start Idling Signal' phase.

Stop Flying

Land the airplane on the ground, throttle is in lowest and idling stage, do not move throttle about 10 seconds, the airplane will automatically stop and locked. Or on the idling stage pull the idling button to the lowest and press again to stop.

Typical flight times for the included battery range from 13 to 15 minutes

Idle setting

Idling five grades default setting is 3 idling button up increasing two grades, down decreasing two grades.

• 1 idling is slowest naturally falling speed is fastest throttle maximum 80%
• 2 idling is a little slow naturally falling speed is faster throttle maximum 85%
• 3 idling is medium naturally falling speed is middle throttle maximum 90%
• 4 idling is fast naturally falling speed is slower throttle maximum 95%
• 5 idling is fastest naturally falling speed is very slow throttle maximum 100%

Diagram Description: Chinese text '水平校准手势' (meaning 'Horizontal calibration gesture') above illustrations of transmitter controls for Throttle and Aileron.

Low Voltage Cutoff [LVC]

LVC decreases the power to the motors when the battery voltage gets low. When the motor power decreases and the LED blinks, land the aircraft immediately and recharge the flight battery.

LVC does not prevent the bat from over-discharge during storage.

NOTICE: Repeated flying to LVC will damage the battery.

To land, slowly decrease the throttle while in a low-level hover. After idle, disconnect and remove the battery from the aircraft after use to prevent trickle discharge. Fully charge your battery before storing it. During storage, make sure the battery charge does not fall below 3.6V per cell.

Post-Flight Inspection and Maintenance

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.

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.

Removing the Propellers

Remove the propeller nuts using the included propeller nut wrench according to the illustration. Install them in the opposite direction.

Diagram Description: An illustration showing how to remove propellers using a wrench, and the quadcopter with propellers attached.

Automatic safety warning and operation

Blades safety protection

When aircraft meets obstacles, it will start protection program. Blades will try to rotate ceaselessly to protect circuit board. When the aircraft crashes an obstacle, it will stop flying automatically. The level must be re-calibrated before starting the flight.

Low voltage alert

The aircraft will alert when the duration of flight is 90%. LED lights flash. The throttle will automatically slow down after 1-2 seconds and the aircraft will descend. Please make sure the aircraft under your control and within your sight in order to prevent damage from dropping down.

Remote controller Low Voltage alert

When the batteries in the controller are lower than 4.5V, LED lights on the controller will flash and make a DIDI alarm to remind the user to change batteries for normal flight. The level must be re-calibrated before starting the flight.
