Safety Advisory Notice for Lithium-Polymer (LIPO) Batteries
LiPo batteries are different from conventional batteries in that their chemical contents
are encased in a relatively lightweight foil packaging. This has the advantage of
significantly reducing their weight but it does make them more susceptible to damage
if roughly or inappropriately handled. As with all batteries, there is a risk of fire or
explosion if safety practices are ignored:
●If you do not plan to fly the quad for a long time, store the battery approximately 50%
charged to maintain battery performance and battery life.
● Please use Hubsan chargers for battery charging.
● Discharging the battery within 5C current , do not over-discharging.
● Do not charge on carpet to avoid fire.
● Batteried need to be recharged if not in use for over 3 months.
1.Charge and store LiPo batteries in a location where a battery fire or explosion
(including smoke hazard) will not endanger life or property.
2.Keep LiPo batteries away from children and animals.
3.Never charge the LiPo battery that has ballooned or swelled.
4.Never charge the LiPo battery that has been punctured or damaged.
5.After a crash, inspect the battery pack for signs of damage. Discard in accordance
with your country’s recycling laws.
6.Never charge the LiPo battery in a moving vehicle.
7.Never overcharge the LiPo battery.
8.Never leave the LiPo battery unattended during recharging
9.Do not charge LiPo batteries near flammable materials or liquids.
10.Ensure that charging leads are connected correctly. Reverse polarity charging can
lead to battery damage or a fire or explosion.
11.Have a suitable fire extinguisher (electrical type) OR a large bucket of dry sand near
the charging area . Do not try to extinguish electrical (LiPo) battery fires with water.
12.Reduce risks from fire/explosion by storing and charging LiPo batteries inside a
suitable container.
13.Protect your LiPo battery from accidental damage during storage and
transportation. (Do not put battery packs in pockets or bags where they can short
circuit or can come into contact with sharp or metallic objects.).
14.If your LiPo battery is subjected to a shock (such as a crash), place it in a metal
container and observe for signs of swelling or heating for at least 30 minutes.
15.Do not attempt to disassemble or modify or repair the LiPo battery.

USB charger to the USB device, such as a computer or a
mobile power charger.
It takes around 110 minutes to have the battery fully
charged. The USB LED indicator blink slowly in red when
charging and will remain solid when the battery is complete
charged. Please unplug the charger and battery when the
charging is completed.
Please make sure the battery is fully charged before use it for the first time.
Please fully charge the batteries to avoid loss of control due to low voltage.
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the local regulations.

The quad copter uses the 5.3-inch propellers which are marked by A and B.
Propellers are consumables, please replace with new ones if there is any damage.

its forward, backward, left and right flight.
Transmitter (Mode 2) X4 Remarks
The throttle stick controls the ascent and
descent .
Push up the stick and the X4 will ascend.
Pull down the stick and the X4 will descend.
When the stick is in the center, the X4 will hover
and hold its alititude automatically .
Move the throttle stick above the center position
to take off. (Move the stick gradually to prevent
the X4 from ascending too quickly.)
UP
Down
The Rudder stick controls the rotate direction
Push the stick to the left and the X4 will rotate
counter-clockwise
Push the stick to the right and the X4 will rotate
clockwise.
When the stick is in the center,the X4 will keep
the current direction and not rotate.
