Motor number 4

Troubleshooting

Problem
350 QX2 will not initialize
GPS will not lock
GPS has reduced resolution
GPS functions not operating
properly
Motors will not start in
Smart Mode
Blades take a long period of
time to shut off after completing
return to home
The quadcopter has trouble
fi nding the home position and
the props will not shut off after
returning home
Possible Cause
The quadcopter was moved during initialization
Heavy overcast
Solar fl ares
Aircraft is indoors
Objects blocking clear access to the sky
(under a metal cover, inside a car, tall buildings, etc...)
Video transmitter nearby
Camera is on
Raised threat level by the U.S. government
The GPS antenna coaxial cable is nicked, cut,
or otherwise damaged
The compass has been exposed to a magnet
The GPS antenna coaxial cable is nicked, cut, or
otherwise damaged
The aircraft is behaving erratically
Aggressive fl ight
GPS signal is not aquired
Pressure calibration is needed
Accelerometer calibration is needed
1. Begin with the transmitter off and connect a fl ight
battery to the 350 QX2.
2. Power on the quadcopter on a level surface and wait
for the rapid blue fl ashing LED to indicate the aircraft
Motor number 2
has entered bind mode.
3. With the throttle stick in the full throttle position,
press/pull the bind button/switch and power on your
transmitter. The quadcopter will acknowledge the as-
signment mode with a loud high, then low tone. If your
transmitter is equipped with a high throttle warning
at startup, it is necessary to disable this alarm prior to
completing this step. After the replacement procedure
is complete, re-activate the high throttle warning in
your transmitter.
4. The motor number and prop direction are molded in
the top of the body. The motors will give an audible
"beep" to indicate which motor to calibrate. When the
motors beep 1 time, spin motor 1 by hand. The motor
will respond with the same number of tones upon
successful assignment.
5. When the motors beep 2 times, spin motor 2 by hand.
6. When the motors beep 3 times, spin motor 3 by hand.
Motor number 3
7. When the motors beep 4 times, spin motor 4 by hand.
When the assignment is successful, the quadcopter
enters emergency mode. Restart the quadcopter.
Re-arm the aircraft, being cautious to avoid any movement during
initialization
Wait for lighter cloud cover and re-lock or disable GPS
Wait for disturbance to subside or disable GPS
Disable GPS
Move aircraft to a clear area
Re-position or remove video transmitter
Turn the camera off, allow the GPS to acquire and then power the camera on.
Wait for threat level to be reduced or disable GPS
Replace the GPS antenna
Move the aircraft away from the magnetic source. In worst case
scenario, the compass may need to be replaced
Replace the GPS antenna
Rebind the aircraft with the GPS function off
Fly level for a few seconds before fl ipping into other modes
Ensure a GPS signal is aquired
