Bindingδ1εTo 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 thebattery cover when the Red indicator light and the Green indicator light blinkslowly alternately.δ2εTo turn on the transmitter, the binding with the quadcopter will succeed after theswitching-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 signalsδ1εFor the first time outdoor, it takes longer to get the GPS signals, please waitabout 2 minutes until the LED light becomes steady.δ2εPlease do not use the GPS Modes (Stable Mode and Return Home Mode)indoor in order to avoid accidents.3. Motor Unlock & Motor Lockδ1εMotor Unlock: Once binding, to put down the throttle stick to the bottom rightposition. When the Red light become steady, the motors are unlocked.δ2εMotor Lock: Once binding, to put down the throttle stick to the bottom leftposition. When the Red light blinks, the motors are locked.4.Calibration:If the quadcopter flies unsteadily, it needs to be recalibrated, the calibrationmethods are as follows:δ1εTo move the throttle stick to bottom left, the Red light and Green light blinksalternately, then it is locked.δ2εTo move the throttle stick to bottom right until the rear red and yellow lightsblink alternately, then to take off the quadcopter and make it hover in the air formore than 20 seconds, and to land and lock it again. The quadcopter can flysteadily after it is re-unlocked.Motor Unlock(left hand) Motor Lock(left hand) Motor Unlock(right hand) Motor Lock(right hand)++++δ6εReturn Home when the quadcopter is out of control: When the quadcopteris out of control, it’ll turn into the Return Home Mode and return back andland in the position when it is unlocked automatically.δ7εThe cancellation of the Return Home Mode: In Return Home Mode andafter the quadcopter returns to the areas in which it can be seen, if youwant 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 SWAon “1” position first and then to turn it back on “0” position, then theReturn Home Mode is canceled.B:If the SWA is on the “1” or “2” position in the Return Home Mode,to setSWA on “0” position first , then to turn it back on “1” position and then toturn 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 quadcopterδ1εLow voltage protection is a protection system designed to avoid the quadcopter tocrash 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.δ2εThere is 1-2 minutes to fly safely after turning into low voltage protection, thereforethe pilots need to adjust the flying distance and to prepare to return safely.6 Low Voltage Protection for the transmitterδ1εLow voltage protection is a protection system designed to avoid the signalinterruption for the transmitter in low battery voltage.δ2εWhen 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.δ3εPlease change the battery in low voltage protection.7 Frequently asked questions and solutionsFrequently askedquestionsSolutionFly in circle inStable Mode1. Poor GPS signal. To change to some other open places.2.2.To fly 3-5 minutes in Manual Mode, and it’ll get the GPS signals automatically1.SWA switch is not set on the “0” position 2.Low battery voltage, please change the battery.To make sure the propellers are installed correctly, to reinstall the propellers if they are installed reversely.Poor GPS signal. To change to some other open places.The quadcopter need to be recalibrated.Motors does not workThe quadcopterdoes not riseDoes notreturn home accuratelyThe quadcoptercan not hover5 Mode Switchedδ1εManual 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.δ2εStable Mode: To take off the quadcopter and keep it in a certain height in Manual Mode, then to setSWA on the “1” position, SWB on the “0” position, the quadcopter will start to hover, then to push thethrottle 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 andthe 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 tobetter control it.δ3εOne Key to Return Home Mode: When you need the quadcopter to return back, to set the SWB onthe “0” position, the SWA on “2” position. Then the quadcopter will return back from the returningpoint to the starting point straightly. If the returning point is higher than 15 meters, the quadcopterwill return back in the current altitude. If the returning point is lower than 15 meters, the quadcopterwill 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 thatthe signal is good.2.It’s suggested to switch to the Stable Mode first or until the quadcopter becomes stable toreturn back.3.To turn the quadcopter to face the taking-off point before returning home, and to turn thequadcopter 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.δ4εFlight Direction Lock Mode: While flying, to set SWA on the “1” position and SWB on the “1” positionfirst. The forward direction will be as per what the head of the quadcopter goes toward when it isunlocked rather than as per what the head of the quadcopter is facing now, and the same analogyapplies 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.δ5εAltitude Sensor Mode: After taking off in the Manual Mode, to set SWB on the “1” position and SWAon the “2” position, then to push the throttle stick to the altitude you want and to set the throttle stickto the middle position, the quadcopter will remain the current altitude constantly, and in theAltitude 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 tobetter control it.2:Constant altitude is relative constant, it can move in a certain range depending on the speed ofthe wind and the weather, therefore you need enough safety space to fly it.2 The instructions for the indicator lights and the statusThe indicator light for the main controlboard calibration, motor unlock/lockinstructional light (YELLOW light/RED light)GPS signal instructional light(GREEN light)The rear downward LED(GREEN)The rear downward LED (GREEN)The front downward LED(RED)The front downward LED (RED)δ1εThe front indicator light: a.
