Return Home

NOTICE:

 Return home will only function if the

350 QX3 has GPS lock.

•   When this feature is activated, the LED will rapidly 

fl ash red.

•  The 350 QX3 will fl y back to its assigned home loca-

tion and land. After landing, the motors may take up 
to 5 seconds to stop.

•  The return home function may be cancelled by 

switching back to Smart or AP Mode using the fl ight 
mode switch.

•  To restart the props after landing in Return Home, 

move both transmitter sticks to the bottom inside 
corners and then back to center.

CAUTION:

 The 350 QX3 will not recognize the 

SAFE Circle

 feature when Return Home is used. 

Activating Return Home may cause the 350 QX3 to 
fl y directly over the pilot if the aircraft was fl own to a 
position behind where the pilot was standing when the 
home position was established.

Activating Return Home

Landing

To land the 350 QX2 AP there are two options: 

•  Guide the aircraft to where you wish to land. Slowly 

reduce the throttle below half to descend and land. 
When the quadcopter has landed, lower the throttle 
completely and press the bind button to stop the 
motors.

•  Activate the Return Home function to return the

350 QX3 to the assigned home location and land 
automatically.

CAUTION:

 Do not activate the 

Return Home

 

function if the 350 QX3 is showing the low

battery indication. 

Manually land the aircraft

immediately.

After Your Flight

1.  Turn off the power switch on the 350 QX3.
2.  Turn off the power to your transmitter.
3.  Unplug and remove the battery from the 350 QX3. 

Recharge your battery following the charging
warnings and instructions.

CAUTION:

 Always disconnect the Li-Po bat-

tery from the aircraft when not fl ying to avoid 

over-discharging the battery. Batteries discharged to a 
voltage below the lowest approved voltage may become 
damaged, resulting in loss of performance and potential 
fi re when batteries are charged.

Location alert

The motors will beep under the following conditions:

•  At any time the props stop spinning after they have 

been initialized. 

•  After 30 seconds of no throttle input (waiting armed 

on the ground).

This will alert the pilot to the location of the aircraft if it 
lands in a location with low visibility. 
Beeping will continue until the battery can no longer 
supply enough power to the motors.
If the quadcopter crash lands and one or more motors 
are stopped by an impact, the quadcopter enters 
emergency mode. The LED will fl ash white and the 
motors will beep loudly.
