GPS has reduced resolution
GPS functions not operating
properly
Motors will not start in
Smart Mode
Motors will not start in
Stability/Agility 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
Throttle trim is not in the correct position
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
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 other-
wise damaged
The aircraft is behaving erratically
Aggressive fl ight
Rate mode switch set to low
GPS signal is not aquired
Rudder trim not centered
Rate mode switch set to low
Rudder trim not centered
Pressure calibration is needed
Accelerometer calibration is needed
1. Begin with the transmitter off and connect a fl ight
battery to the 350 QX.
2. Power on the quadcopter on a level surface and wait for
Motor number 2
the rapid blue fl ashing LED to indicate the aircraft 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 assignment mode
with a loud high, then low tone. If your transmitter is
equipped with a high throttle warning at startup, it is nec-
essary 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.
7. When the motors beep 4 times, spin motor 4 by hand.
Motor number 3
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
The trim may need to be adjusted a click above or below center
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
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 sce-
nario, 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
Set transmitter dual rate switch to hi
Ensure a GPS signal is aquired
Center the rudder trim
Set transmitter dual rate switch to hi
Center the rudder trim
