Flying the 350 QX2

Takeoff

Increase the throttle slightly above low stick (10–15%). 
The 350 QX2 altitude in 

Smart Mode

 corresponds 

to the throttle position. Low throttle is on the ground, 
slightly raising the throttle will produce a low hover, 
and the higher the throttle position, the higher the 350 
QX2 will ascend until it reaches its maximum altitude 
(approximately 45 meters).

Explore the fl ight envelope of the 350 QX2 in 

Smart 

Mode

 without fear of losing orientation. See the 

diagrams in the 

Flight Modes Explained

 section for 

more details on the aircraft’s function in 

Smart Mode.

 

In 

Smart Mode,

 the direction the aircraft is pointing 

does not affect the control, and the aircraft’s response 
relative to you (

the pilot location

) does not change with 

orientation. 

AP Mode

 and 

Stability Mode

 operate more 

like a conventional RC helicopter or multicopter.

Return Home

•  When this feature is activated, the 350 QX2 

will fl y back to its assigned home location 
and land. After landing, the motors may take 
up to 5 seconds to disarm. If the motors take 
more than 20+ seconds to disarm, perform 
the Pressure Sensor Calibration.

•  To restart the props after landing in 

Return Home, 

fully lower the throttle, then quickly move the rudder 
stick fully left and then fully right.

CAUTION:

 The 350 QX2 will not recognize the 

SAFE Circle

 feature when 

Return Home

 is used. 

Activating 

Return Home

 may cause the 350 QX2 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.

Switch to position 1.

Returning the switch to position 0 
will stop the 

Return Home

 program.

Landing

To land the 350 QX2 there are two options: 

•  Guide the aircraft to where you wish to land and re-

duce the throttle. Hold the bind button for 1 second 
after landing to disarm the motors.

•  Activate the Return Home function to return the

350 QX2 to the assigned home location and land 
automatically.

CAUTION:

 Do not activate the 

Return Home

 

function if the 350 QX2 is showing the low

battery indication. 

Manually land the aircraft

immediately.

After Your Flight

1.  Turn off the power switch on the 350 QX2.
2.  Turn off the power to your transmitter.
3.  Unplug and remove the battery from the 350 QX2.

CAUTION:

 Always disconnect the Li-Po battery 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.
