Notice
(1) This product is not an ordinary toy but a piece of complicated equipment
which is integrated with professional knowledge by mechanic, electronic, air
mechanics, high-frequency emission etc., so it should be installed and
adjusted correctly to avoid accidents. The user must always operate in a safe
manner. We undertake no liability for human injury or property damage caused
by improper operation as we could not control the procedure of installation,
use and operation of this drone.
(2) This drone is suitable for experienced RC drone user aged 14 years or above.
(3) The flying field must be legally approved by your local government.
(4) We undertake no liability for those accidents caused by improper operation,
use and control of the drone after sale of the product.
(5) We has entrusted the distributor to provide technology support and after-sale
service. If you have any question about use, operation, repair etc., please
contact your local distributor.
1. Important Statement:
(2) Keep away from humid environment
(3) Safe operation
2. Safety Precautions:
(1) Keep away from obstacles and crowd
Keep away from crowd when flying because a flying RC drone is very dangerous.
Improper assembly, broken main frame, defective electronic equipment or unskilled
operation all may cause unpredictable accidents such as drone damage or human
injury. Please pay special attention to safety operation and have good knowledge
of accident responsibility that the user may cause.
The speed and status of a flying RC drone is uncertain and it may cause
potential danger. So the user must keep away from crowd, tall building, power
lines etc. when operating a flying RC drone. Do not fly a RC drone in rainy,
storm, thunder and lighting weather for the safety of user, around people and
their property.
The drone inside is consisted of precise electronic components. Humidity or
water vapor may damage electronic components and cause accident.
Please operate the RC drone in accordance with your physical status and
flying skill. Fatigue, listlessness and improper operation may increase the
rate of accident.

(4) Please strictly obey the order of turn on and turn off before operation. Turn on
the transmitter power first and then turn on the drone power before flying;
turn off the drone power first and then turn off the transmitter power when
finish flying. Improper turn on and turn off order may cause the drone out of
control and threaten people’s safety. Please cultivate a correct habit of turn on
and turn off.
(5) Make sure the connection is solid between battery and motor etc. The ongoing
vibration may cause bad connection of power terminal make the drone out of
control.
(7) The drone should be controlled within max control distance. Do not fly the
drone near tall building, high voltage cable or other place with signal interference.
Or may cause signal interruption and the drone will be out of control, which
may result in accident.
(6) Improper operation may cause drone crash, which may arouse motor
defective and noise, and then effect the flying status or even stop flying.
Please go to the local distributor to buy new parts for replacement so that the
drone will return to its best status.
(1) Flying field must be spacious enough and we suggest at least
8M (length)*8M (width)*5M (height).
(2) Make sure the drone battery and transmitter battery are fully charged.
(3) Make sure the Left Stick of the transmitter in the middle position.
3. Check List Before Flight
(4) Keep away from rotating parts
Rotating Parts can cause serious injury and damage. Keep face and body
away from rotating motors.
(5) Keep away from heat
(6) Please do not touch the hot motor to avoid being burnt.
The RC drone is made of metal, fiber, plastic, electronic components etc.
Keep away from heat and sunshine to avoid distortion and damage.

SAFETY ADVISORY NOTICE
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:
- Charge and store LiPo batteries in a location where a battery fire or explosion
(including smoke hazard) will not endanger life or property.
- Keep LiPo batteries away from children and animals.
- Never charge the LiPo battery that has ballooned or swelled.
- Never charge the LiPo battery that has been punctured or damaged.
- After a crash, inspect the battery pack for signs of damage. Discard in
accordance with your country's recycling laws.
- Never overcharge the LiPo battery.
- Never leave the LiPo battery unattended during recharging.
- Do not charge LiPo batteries near flammable materials or liquids.
- Ensure that charging leads are connected correctly. Reverse polarity charging
can lead to battery damage or a fire or explosion.
- 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.
- Reduce risks from fire/explosion by storing and charging LiPo batteries inside a
suitable container.
- 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), 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.
This drone is powered by a Lithium-Polymer (LiPo) battery.
If you do not plan to fly the drone for a week or more, store the battery
approximately 50% charged to maintain battery performance and battery life.
