LI-PO BATTERY CARE
Avoid Overheating
Your batteries will sometimes be warm/hot to the touch after use. This is normal, but beware that battery
components will fail if not allowed to cool down between uses. Also, do not leave batteries exposed to
direct sunlight.
Store Properly
Store batteries at room temperature, between 5C°/40°F and 27°C/80°F.
Use Carefully
• Leave time between charging and using the battery
• To extend the lifetime of the battery, always keep about 20% of the power remaining in the drone
battery (rather than completely draining it)
• If the battery is pushed beyond its limits, the battery could get hot and the performance will drop
• When using the battery for a long time, the battery will increase in temperature. If it is sealed, the air
inside will inate rapidly causing further heating
Charging
• DO NOT overcharge the battery; never charge batteries unattended, and stop charging as soon as your
batteries indicate they are charged
• DO NOT attempt to charge batteries that appear damaged in any way (cracking, swelling, discoloration, etc.)
• If you feel a battery isn’t charging properly, try using another charger if possible. If you nd your battery
or charger is defective, please visit force1rc.com for a replacement, or email us at [e-mail]
• To inspect a battery, remove it from the device and examine the battery, battery pins and contacts. If
you notice damage, please visit force1rc.com for a replacement, or email us at [e-mail]
• Check your battery and connections after every crash
• Please use genuine factory parts and replacements from force1rc.com
LI-PO BATTERY DISPOSAL & RECYCLING
Do not put lithium-polymer batteries in household trash.
Please contact your local waste management agency or LI-PO
battery recycling center for more info.

PREFLIGHT OPERATION
FREQUENCY PAIRING
1. Turn on the transmitter switch (Fig. 19) and the power indicator light flashes rapidly. Push the Left Stick
all the way down to the lowest position and then release. The Left Stick will back to the middle position
automatically. (Fig. 20 / 21) The power indicator light flashes slowly, which indicates the transmitter is
ready for frequency pairing.
2. Install the battery to the mounted box in the drone and then power on the drone (Fig. 22).
3. Put the drone on the flat surface, the drone body lights turn from flashing to solid bright, which
indicates successful frequency pairing.
Important Notice: Please make sure the drone is placed in the horizontal position after powering on
the drone, so that the drone can work well.

CHECKLIST BEFORE FLIGHT
1. The camera is in front of the drone. Keep the drone front facing away from you.
2. Power ON the drone and check the direction of the rotating propellers. The left front and right rear
A propellers should be rotating clockwise while the right front and left rear B propellers should be
rotating counterclockwise.
3. Activate (unlock) motors: Move the Left Stick and Right Stick at the same time as Figure 23 shown (45
degree inward) to start the motors and repeat previous step again to lock the motors.

4. After activating the motors, push the left stick up slowly to fly the drone upwards. Pull down the left stick
slowly to the lowest end, then the drone will land on the ground slowly.
5. It’s recommended to repeat Step 2-4 for practice.
6. Adjust the trim using the trimmer button if the drone moves in a certain direction too much while flying.
CALIBRATION INSTRUCTION
Please follow the below steps to calibrate the drone if it becomes imbalanced after crashing and the trim
buttons are not balancing the drone adequately.
1. Power OFF the drone, then turn off the transmitter switch.
2. Turn on the transmitter switch, push the left stick all the way down to the lowest position (Fig. 24)
and then release. The left stick will spring back to the middle position automatically (Fig. 25). The
transmitter is ready for frequency pairing mode.
3. Power on the drone and put it on a flat surface in a horizontal position. The drone body lights change
to solid bright, which indicates successful pairing.
4. Do not move the left stick before successful calibration. Push the right stick down and to the right, then
release (Fig. 26). The drone body lights flash, which indicates that the drone is calibrating. When the
lights turn solid, the drone has been successfully calibrated.
Notice: When the drone is fiercely impacted or crashed, the gyro may not recover its original
position and cause difficulty in control, if this is the case, then you need to power OFF and power
on again to calibrate.

FUNCTIONS
TAKE OFF/ONE BUTTON TAKE OFF/LANDING MODES
LANDING METHODS
Method 1 (Landing): When flying, push the left stick all the way down to the lowest position (Fig. 26) and
hold it until the motors stop and the drone will slowly land on the ground.
Method 2 (One Button Landing): When ying, press the Take Off / Landing / Emergency Stop Button once
(Fig. 28), and the drone will land on the ground automatically. (When using this function, do not touch
the left stick. Moving the left stick will cancel the auto landing)
Emergency Stop: When the drone is in an emergency situation or you need to land the drone, press the
Take Off / Landing / Emergency Stop Button immediately and hold it for more than 1 second (Fig. 28).
The propellers will stop immediately and the drone will drop down to the ground.
NOTE: Do not use the Emergency Stop function unless in an emergency situation. The drone will fall
down suddenly after all propellers stop.
Method 1 (Take Off): After successful frequency pairing, push the left stick and right stick as shown in
Figures 25-27 to start the motors and then release. Then push up the left stick to fly up the drone to
desired altitude and then release the stick.
Method 2 (One Button Take Off): After successful frequency pairing or motors activated, press the Take
Off / Landing / Emergency Stop Button (Fig. 28). The drone will y up automatically and keep ying at
an altitude of approximately 4 meters.

HIGH/MEDIUM/LOW SPEED MODE SWITCH
Press on the button once to hear ONE BEEP which means Low Speed Mode “L”. Press the button a sec-
ond time and you will hear TWO BEEPS which means it’s on Medium Speed Mode “M”. Press the button
a third time to hear THREE BEEPS which means it’s on High Speed Mode “H”.
FIGURE 27
Low Speed Mode (Mode 1)
Low Speed Mode is suitable for beginners
Medium Speed Mode (Mode 2)
Medium Speed Mode is suitable for skillful pi-
lots and for use in a gentle breeze.
High Speed Mode (Mode 3)
High Speed Mode is suitable for experts and
aerial stunts outdoors.
ALTITUDE HOLD MODE
Altitude hold mode indicates that the drone maintains a consistent altitude while allowing roll, pitch, and
yaw to be controlled normally. It makes it easier to control the drone for beginners and more stable for
aerial photography.
Push the THROTTLE/RUDDER STICK up/down to y the drone up/down at certain altitude and then
release the Stick. The Stick will return to the center position (Altitude Hold Center) as shown in Figure 29.
And the drone will keep ying at current altitude. Repeat above steps if you want to change the drone
altitude (Default mode).
Note: The Altitude Holding Mode cannot be used when the blades are accidentally deformed or
damaged.

HEADING HOLD MODE (HEADLESS MODE)
Drones generally have a front and back indicated by LED lights or colored propellers. Before take off,
users are instructed to position the head of the drone away from the user. When flown in daylight or at a
far distance, determining which side is the front or back becomes difficult. When the drone is in Headless
Mode, push the Right Stick forward/backward/left/right and the drone will fly accordingly.
Prerequisite: Position the drone in such a way that its front is your front (see Fig. 30).
Tip: Do not change the orientation of the transmitter (see Fig. 31) after entering headless mode.

alternately, it shows the drone enters Heading Hold
mode, press the button again, then the LED turns
solid and the drone exits from Heading Hold mode.
LOW BATTERY ALARM
When the drone battery is low, the transmitter will constantly beep to remind the user to land the drone
as soon as possible. The flip function will turn off automatically when the drone battery is low.
OUT OF RANGE ALARM
When the drone is going to fly out of the max remote control distance, the transmitter will double beep
continuously to alarm the user to fly the drone back immediately. Otherwise the drone may lose control
and fly away.
MOTORS STUCK PROTECTION
1. When the propellers get stuck, then the drone LED will flash quickly and activate stuck protection
function and the motors stop running.
2. Pull down the left stick to the lowest position, the drone LED will get a solid light and stuck protection
will be released and the drone can fly again.
