FQA
What's happen in flight? Step of checking
Solution
1.The battery can work?
1. Replacing the battery
The drone and radio can't bind
The drone without power, the
power indicator light is not bright
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
signal lights of the receiver is flashing slowly, that
means we need clear the ID code)
2，Clear ID code: using the Bind plug-in line inset the AUX7 port at the condition
of without electricity, then connecting the power to clear the fixed 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.
Cann't unlock
1，The compass cable have properly connected to the
main controller?
1，Reconnecting the cable of compass to the main controller or change the
compass.
2，The function of the compass works?（We can find it
from the MissionPlanner）
2，Recalibrate the compass, Pls. be notes that the drone should be at the
horizontal place and it should be far away from the electromagnetic induction place
when it was calibrated
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.
There is no respond from the
Landing skid
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 ）
The drone is vibration
No DOS video of the radio
Flight instability, always go to the
special side.
1，The drone is at the horizon level when it was
connect ed with the MissionPlanner?
1，Calibrating the accelerometer（Make sure the UVA at the horizon level and the
direction is correct.）
2，The electronic compass direction is disorder?
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，Propellers are deformation?
The hardness of the propellers is enough?3，Propellers
are deformation?
The hardness of the propellers is enough?
3，Using the new propellers
4，The main controller is at the horizon level position?
（Especially for QR X350PRO）
4，Make sure that the main controller is at the horizon level postion.
5，The spin button of the radio's channel at the middle
place?
5，Be sure all of the spin button at the "0" position
6，Motors and ESC can work well?
6，Replacing the motor or ESC.
1，Propellers are deformation?
The propellers wered damaged?1，Propellers are
deformation?
The propellers wered damaged?
1，Replacing the new propellers
2，Motors are vibration?
2，Replacing motors to test again.
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.
The drone can't fix point correctly,
it flies up and down, and it can't
stay at the point high position
unders the GPS condition
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
3，The accelerometer can work well?
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.
Gimbal vibration
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.
