FQA What's happen in flight?

The drone without power, the power indicator light is not bright

The drone and radio can't bind

Step of checking

Solution

1.The battery can work?

1. Replacing the battery

2.The lights of the power supply circuit connection is correct ?

2，Reconnect the power cable

3，The power board can work?

3，Replacing the power supply board

1，The connection of the cable is correct?

1，Be sure that cables inside the drone are connected perfect.

2，If the ID code was fixed ID code by the user;（If the 2，Clear ID code: using the Bind plug-in line inset the AUX7 port at the condition signal lights of the receiver is flashing slowly, that of without electricity, then connecting the power to clear the fixed ID code.) means we need clear the ID code) 3，The electronic compass can work? The compass cable have properly connected to the main controller?

3，Reconnecting the cable of compass to the main controller or change the compass.

1，The compass cable have properly connected to the 1，Reconnecting the cable of compass to the main controller or change the compass. main controller? 2，Recalibrate the compass, Pls. be notes that the drone should be at the

2，The function of the compass works?（We can find it horizontal place and it should be far away from the electromagnetic induction place from the MissionPlanner） when it was calibrated

Cann't unlock

There is no respond from the Landing skid

3，Upgrading the software（.bin）and it parameter data（.param）

3，Upgraded the software by Walkera FlyConfig（.bin）and upgraded the parameter data by MissionPlanner（.param）

4，Recalibrated the radio

4，Recalibrate the radio at Walkera FlyConfig，Pls. notes that each of channels of the switch in the radio should be tested

5，The radio's setting is correct ?

5，It should be selected by Airplane when it was checked the "type Select"（It would be a safe and best way to TRANSFER the data from a working radio ）

6，Using another working radio to check if it can unlock?

6，Using another working radio to test if drones can unlock.

1，The worm servos can work?

1，Replacing the worm servos

2，Cables inside the drone are connecting well? Or it was disconnected?

2，Be sure that the cable of the steering gear fixed block and the power board is connecting.

3，Cables are working

3，Be sure that channels of worm servos are connected very well

4，The radio's channels setting are correct?

4，Re setting the Gear switch channel accoring to the manual said.（It would be a safe and best way to TRANSFER the data from a working radio ）

1，The drone is at the horizon level when it was connect ed with the MissionPlanner?

Flight instability, always go to the special side.

2，The electronic compass direction is disorder? 3，Propellers are deformation? The hardness of the propellers is enough?3，Propellers are deformation? The hardness of the propellers enough? 4，The main controller is at theishorizon level position? （Especially for QR X350PRO） 5，The spin button of the radio's channel at the middle place?

1，Calibrating the accelerometer（Make sure the UVA at the horizon level and the direction is correct.） 2，Pls. be sure that the drone should be calibrate at the horizon level and it should be far away from the electromagnetic induction place when it was calibrated 3，Using the new propellers 4，Make sure that the main controller is at the horizon level postion. 5，Be sure all of the spin button at the "0" position

6，Motors and ESC can work well? 1，Propellers are deformation? The propellers wered damaged?1，Propellers are deformation? The propellers wered damaged? 2，Motors are vibration?

6，Replacing the motor or ESC.

3，All of the cable of the drone connect very well?

3，Screws are tight enough?

4，The body of the drone is hardness enough?

4，Replacing the body sets.

1，The number of satellites is enough as the manual request?

1，The drone shouldn't take off until the GPS signal is very well(more than 8 satellites)

2，The electronic compass can work well?

2，Recalibrate the compass, Pls. be sure that the drone should be calibrate at the horizon level and it should be far away from the electromagnetic induction place when it was calibrated

1，Replacing the new propellers 2，Replacing motors to test again.

The drone is vibration

The drone can't fix point correctly, it flies up and down, and it can't 3，The accelerometer can work well? stay at the point high position unders the GPS condition

Gimbal vibration

No DOS video of the radio

3，Upgraded the parameter data by MissionPlanner（.param）, pls. be sure that the drone should be at the horizon level.

4，The barometer can work well?

4，The barameter should be working very well when you watch it in the MissionPlanner; you need replace a new one if there is something wrong of the data.

5，Motors work well?

5，Making sure that each of the motor works well.

1，The camera was installed very well ?

1， Camera should be interference fit, making sure both of screws of the camera tightly enough

2，The center gravity of the gimbal is right?

2，Be sure that the antenna of the camera and the Counter weighter are installed very well.

3，The motor of the gimbal is vibration?

3，Replace the gimbal motor or replace the whole gimbal to test

1，The channel of the camera and radio matchs each other?

1，Make sure that the camera channel should agree with the radio's. The factory default channels is channel 8 .

2，Cables connect is correct?

2，Make sure that the video cable is connected very well and pls. turn on the camera.
