Preparing the 350 QX3 For Flight

CAUTION:

 When the home location is set (

step 6

), the 350 QX3 must be approximately 16 feet (5 meters) from where the pilot will stand during fl ight, point-

ing away from the pilot. If the aircraft is pointed in any other direction, the 

SAFE Circle

 feature will not function as expected and may result in personal injury 

or damage to property. Once the aircraft’s motors are started, do not change your position.

1.  Power on the transmitter with the fl ight mode set to 

Smart Mode.

2.  Remove the battery hatch. Install a fully charged

battery pack, connect the blue EC3

 battery connector 

and reinstall the hatch.

3.  With the quad on a level surface, turn on the power 

switch and allow the 350 QX3 to initialize.
If the GPS is enabled, wait for the GPS signal to be
acquired (solid green LED).

IMPORTANT:

 While in 

Smart Mode,

 the motors will not 

start if a GPS signal has not been acquired.

4.  Move the aircraft to the desired home location and

orient the aircraft pointed away from the pilot.

5.  Step back approximately 16 feet (5 meters) from the 

home location.

6.  To start the motors, move both sticks into the bottom 

inside corners, then back to center.

7.  The props will begin to spin. The home position for GPS 

functions is set and your aircraft is ready to fl y. 

Lower the throttle stick fully and hold the bind button to 
stop the motors after fl ight.

Flying the 350 QX3

Takeoff

The throttle control for the 350 QX3 changes the altitude 
of the quadcopter by moving the throttle stick above or 
below half throttle. As you move the throttle stick above 
half, the quadcopter will climb. As you move the throttle 
stick below half, the quadcopter will descend. The farther 
away from half you move the throttle stick, the faster the 
quadcopter will climb or descend.

To takeoff, slowly advance the throttle to slightly above 
half. The 350 QX3 will slowly climb. When the quadcopter 
reaches the desired height, ease the throttle back to half 
to hold that altitude.

Explore the fl ight envelope of the 350 QX2 AP 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

 operates more like a conventional 

RC helicopter or multicopter.

Descend

NOTICE:

 If you begin to lose control, release the control 

sticks and the model will self-level.

Pay close attention to the LED while fl ying. If at any time 
the LED indicates the fl ight battery voltage is low (below 
10.6V), as shown In the LED code section, land the 350 
QX3 immediately and charge the fl ight battery.
