5 Mode Switched 

( 1 ) Manual Mode: To set SWA on the ·o· 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, tum 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 ·o· 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:Un 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 

3.1n 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:Un Return Home Mode, to make sure the GPS signal indicator light remain steady, it means that 

the signal is good. 

2.1rs suggested to switch to the Stable Mode first or until the quadcopter becomes stable to 

return back. 

3. To tum the quad copter to face the taking-off point before returning home, and to tum the 

quadcopter to the positon while taking-off after it returns back. 

4.Mer returning back, the quadcopter will lock automatically; if you need to restart the motor, 

please set the SWA to ·o· 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 quad copter goes toward when it is 

unlocked rather than as per what the head of the quad copter is fadng 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. 

2.1n this mode, the quadcopter can return safely in long distance or in poor light 

(5) Altitude Sensor Mode: Mer 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. 

NOTE:1. In Altitude Sensor 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 

2:Constant altitude is relative constant, 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 
(6) 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:lf 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. 

voltage is between 1 0.2V to 1 0.4V, 

the quadcopter activate the low voltage 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 ne~d to ad the flying distance and to prepare to return safely. 

< 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 ... n 

sound, and the power indicator light will blink slowly at the same time. 

(3) Please change the battery in low voltage protection.
