assistance of an experienced pilot before attempting to y our product for the rst time.
2 SAFETY NOTES
2.1 Caution
R/C quadcopter have parts that move at high speed, thus posing a certain degree of
danger. Pilots are responsible for any actions resulting in damage or injury from the
improper operation of their R/C aircraft models.
Choose a wide open space without obstacles. Do not operate R/C aircraft near buildings,
crowds of people, high voltage cables, or trees to ensure the safety of yourself, others and

SAFETY ADVISORY NOTICE
[Lithium-Polymer (LiPo) Batteries]
LiPo batteries are dier from conventional batteries in that their chemical contents
are encased in a relatively insubstantial foil packaging. This has the advantage of
signicantly reducing their weight, but does make them more susceptible to damage if
roughly or inappropriately handled. As with all batteries, there is a risk of re or explosion
if safety practices are ignored:
Charge and store LiPo batteries in a location where a battery re or explosion
(including smoke hazard) will not endanger life or property.
Keep LiPo batteries away from children and animals.
Consider how you would deal with a LiPo battery re/explosion as part of your
normal home Fire Safety & Evacuation Planning.
Never charge the LiPo battery that has ballooned or swelled due to over-/under-
charging or from a crash.
Never charge the LiPo battery that has been punctured or damaged in a crash (After
a crash, inspect the battery pack for the sign of damage. Discard in accordance with
your country’s recycling laws.).
Never charge the LiPo battery in a moving vehicle.
Never over charge the LiPo battery.
Never leave the LiPo battery unattended during recharging.
Do not charge LiPo batteries near ammable materials or liquids.
Ensure that charging leads are connected correctly. Reverse polarity charging can
lead to battery damage or a re or explosion.
Have a suitable re extinguisher(electrical type) OR a large bucket of dry sand near
the charging area . Do not try to extinguish electrical (LiPo) battery res with water.
Reduce risks from re/explosion by storing and charging LiPo batteries inside a
suitable container: a LiPo Sack or metal/ceramic container is advised.
Monitor recharging LiPo batteries for signs of overheating.
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.).
If your LiPo battery is subjected to a shock (such as a crash) you should place it in
a metal container and observe for signs of swelling or heating for at least 30 minutes.
Do not attempt to disassemble or modify or repair the LiPo battery.

moisture may cause the model to malfunction resulting in loss of responsiveness, or a
crash.
2.4 Proper Operation
For the safety purpose, please only use hubsan’s spare parts for replacement.
2.5 Always Be Aware Of The Rotating Blades
When in operation, the rotor blades will be spinning at high speed. The blades are capable
of inicting serious body injury and damage to the environment. Be cautious of your
actions and careful to keep your body and loose clothing away from the blades. Never
take your eyes o the model or leave it unattended while it is turned on. Stop operation
immediately if the model ies out of your view. Once landed, immediately turn o the
model and transmitter.
2.6 Avoid Flying Alone

7.1 Power-On (Failsafe) Procedure
Your X4’s ight contoller is coded with a Power-On failsafe.
This is designed to ensure that the X4’s motor will not start unless it detects a suitable
radio-control signal when the LiPo battery is connected. The correct Start-Up sequence is
as follows:
7.1.1 Make sure the throttle stick is in the full down position.
7.1.2 Power on the transmitter and the red LED will be blinking. Please do not move any
other stick or trim before the TX and X4 match code and bind, or the X4 will drift. The TX
LED will turn green when the TX binds with the X4.
7.1.3 Apply power on the X4 by connecting the ight battery plug with correct polarity.
Please disconnect the X4 battery plug after turning o the TX when you stop ying.
