1.1 Important Notes
This RC quadcopter is not a toy, it utilizes various high-techs to provide superior
performance.
Please read this manual carefully before operating this product. Any improper use of this
product will result in serious injury. Be aware of your personal safety, safety of others and
your surrounding environment.
We recommend that you obtain the assistance of an experienced pilot before attempting
to y our product for the rst time.
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 your model.
Operate this unit within your ability. Do not y when tired or after drinking or when
impaired by medication. Improper operation may cause damage to people and property.
2.2 LiPo Battery Recharging
Your quadcopter is powered by a Lithium-Polymer (LiPo) battery.
Never recharge your battery whilst it is inserted in your model. It can catch re leading to
the total destruction of the item.
If you do not plan to y your model for a week or more, store the battery approximately
50% charged to maintain battery performance and life. To achieve a 50% charge, y the
model until the battery requires recharging. Charge the battery for half the time typically
required to fully charge the battery.
2 SAFETY NOTES
12. One or more motors stop working
Answer: (1) Motor is damaged. Replace the motor.
(2) The motor connections(s) are disconnected. Resolder.
(3) An FET on the ight controller looks burned. Replace the ight controller.
13. The X4 is still drifting excessively when hovering even after a good accelerometer calibration.
Answer: Set it on a level surface and shim the side that it drifts to with a few sheets of paper (the
number of sheets will vary depending on the amount of drift), so it can calibrate the
accelerometers with a level oset angle.
14. The camera can’t recording
Answer: Press the button beside the SD card slot, the red light will blink, indicating the recording
start. When the recording is nished please press the button again to save it, then the red light

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 helicopter 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.
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:
!
10. The motors are a little gritty and do not spin as freely after crashes.
Answer: You can hear grinding and see that motor is not spinning freely by icking the prop.
Press the shaft down from the top of the prop and motor to x the problem, or replace the
motor.
11. The arm of the X4 separates after a hard landing or crash.
Answer: This is a special design to absorb the impact from hard crashes. Simply force the arms to
snap back into the joint position by hand as shown in the picture.
9. LED removal & installation.
Removal: Unscrew and remove the lower shell and the rubber feet. Then unsolder the red and
yellow wires.
Installation: Solder the red wire on anode/positive (+), the yellow on cathode/negative (-), press
the LED wires rst, then the motor wires in the leg slots. Install the lower shell, then the rubber
feet. You can determine the color of the LED lights by looking at the color of the LED wire
