(2) Keep away from humid environment
(3) Safe operation
(1) Keep away from obstacles and crowd
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 lowest 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.
