Basic operation
1. Binding
(
1)To insert the battery into the quadcopter battery container and connect them.
The Red indicator light and the Green indicator light will blink rapidly alternately,
please do not move and shake the quadcopter at this moment; to close the
battery cover when the Red indicator light and the Green indicator light blink
slowly alternately.
(
(
2)To turn on the transmitter, the binding with the quadcopter will succeed after the
switching-on sound of the transmitter stops.
(NOTE: 1.To put the throttle stick to the lowest position before the binding.
2.SWA,SWB switches need to be in the “0” position.)
2. To Receive The GPS Signals
(
1)For the first time outdoor, it takes longer to get the GPS signals, please wait
about 2 minutes until the LED light becomes steady.
(
(
2)Please do not use the GPS Modes (Stable Mode and Return Home Mode)
indoor in order to avoid accidents.
3. Motor Unlock & Motor Lock
(
1)Motor Unlock: Once binding, to put down the throttle stick to the bottom right
position. When the Red light become steady, the motors are unlocked.
(
(
2)Motor Lock: Once binding, to put down the throttle stick to the bottom left
position. When the Red light blinks, the motors are locked.
4.Calibration:
If the quadcopter flies unsteadily, it needs to be recalibrated, the calibration
methods are as follows:
(
(
1)To move the throttle stick to bottom left, the Red light and Green light blinks
alternately, then it is locked.
(
(
2)To move the throttle stick to bottom right until the rear red and yellow lights
blink alternately, then to take off the quadcopter and make it hover in the air for
more than 20 seconds, and to land and lock it again. The quadcopter can fly
steadily after it is re-unlocked.

Return Home when the quadcopter is out of control: When the quadcopter
is out of control, it’ll turn into the Return Home Mode and return back and
land in the position when it is unlocked automatically.
(
7)
The cancellation of the Return Home Mode: In Return Home Mode and
after the quadcopter returns to the areas in which it can be seen, if you
want to stop the Return Home Mode, you need to do the following steps:
A:If the SWA is on the “0” position in the Return Home Mode, to set SWA
on “1” position first and then to turn it back on “0” position, then the
Return Home Mode is canceled.
B:If the SWA is on the “1” or “2” position in the Return Home Mode,to set
SWA on “0” position first , then to turn it back on “1” position and then to
turn it on “0” position again, then the Return Home Mode is canceled.
NOTE:1. It is suggested to use only Manual Mode, Stable Mode and One Key to Return Home Mode for the beginners,
it means to use the SWA switch only;
2. It is required to take off in the Manual Mode.
5 Low Voltage Protection For The Quadcopter
(
1)
Low voltage protection is a protection system designed to avoid the quadcopter to
crash in low battery voltage. When the battery voltage is between 10.2V to 10.4V,
the quadcopter will activate the low voltage alarm and give out the “beep, beep…”
sound, and the front and rear indicator LED lights will blink at the same time.
(
2)
There is 1-2 minutes to fly safely after turning into low voltage protection, therefore
the pilots need to adjust the flying distance and to prepare to return safely.
6 Low Voltage Protection For The Transmitter
(
1)
Low voltage protection is a protection system designed to avoid the signal
interruption for the transmitter in low battery voltage.
(
2)
When the battery voltage is low, the transmitter will give out the “beep, beep…”
sound, and the power indicator light will blink slowly at the same time.
(
3)
Please change the battery in low voltage protection.

5 Mode Switched
(
1)Manual Mode: To set SWA on the “0” position, after the motors are unlocked, to push the throttle stick,
then it can go forward/backward, go up/down, do left-side flying/right-side flying, turn left /right, etc.
(
(
2)Stable Mode: To take off the quadcopter and keep it in a certain height in Manual Mode, then to set
SWA on the “1” position, SWB on the “0” position, the quadcopter will start to hover, then to push the
throttle stick in the middle position, the quadcopter will keep in the current altitude and position.
NOTE:1.In stable Mode, the GPS signal indicator light should be steady, it means that the signal is good.
2.Stable is relative stable, it can move in a certain range depending on the speed of the wind and
the weather, therefore you need enough safety space to fly it.
3.In Stable Mode, the throttle stick needs to be in the middle position, it gives out
“beep, beep, beep...”sound when the throttle stick is in the middle position in order for you to
better control it.

(
3)One Key to Return Home Mode: When you need the quadcopter to return back, to set the SWB on
the “0” position, the SWA on “2” position. Then the quadcopter will return back from the returning
point to the starting point straightly. If the returning point is higher than 15 meters, the quadcopter
will return back in the current altitude. If the returning point is lower than 15 meters, the quadcopter
will rise to the 15 meter height and then to return back.
NOTE:1.In Return Home Mode, to make sure the GPS signal indicator light remain steady, it means that
the signal is good.
2.It’s suggested to switch to the Stable Mode first or until the quadcopter becomes stable to
return back.
3.To turn the quadcopter to face the taking-off point before returning home, and to turn the
quadcopter to the positon while taking-off after it returns back.
4.After returning back, the quadcopter will lock automatically; if you need to restart the motor,
please set the SWA to “0” position first and then to unlock the motors.

(
4)Flight Direction Lock Mode: While flying, to set SWA on the “1” position and SWB on the “1” position
first. The forward direction will be as per what the head of the quadcopter goes toward when it is
unlocked rather than as per what the head of the quadcopter is facing now, and the same analogy
applies to other directions.
NOTE:1. This mode is not appropriate for the beginners, it needs more skills and experiences to do so.
2.In this mode, the quadcopter can return safely in long distance or in poor light.

5)Altitude Sensor Mode: After taking off in the Manual Mode, to set SWB on the “1” position and SWA
on the “2” position, then to push the throttle stick to the altitude you want and to set the throttle stick
to the middle position, the quadcopter will remain the current altitude constantly, and in the
Altitude Sensor Mode, the quadcopter will fly in constant altitude.
