Calibration Procedures

Compass calibration procedure:

NOTICE:

 The following procedure has to be

completed within 30 seconds after entering compass 
calibration mode.

1. Power the transmitter.
2. Power on the 350 QX3 and face the

quadcopter pointing North.

3. Cycle the top left transmitter switch completely

4 times as shown at the left.

4. The 350 QX3 indicates it has entered compass

calibration mode by slowly fl ashing the LED orange.

5. When the LED begins to fl ash rapidly, complete

all 4 rotations of the 350 QX3 as shown in the
illustration at left within 30 seconds, rotating the 
quad 45° counterclockwise between each rotation.

6. Hold the quad level, facing North and check the LED.

Green = Ready
Red = Repeat Compass Calibration

Accelerometer calibration procedure:

1. Power on the transmitter and 350 QX3 and

place the quad on a fl at, level surface.

2. While holding the bind switch on the transmitter, 

cycle the top left switch 4 times as shown at the left.

3. The 350 QX3 will emit a series of slow tones

followed by a series of rapid tones, indicating the 
calibration has started.

4. Do not move the 350 QX3 while it performs the

accelerometer calibration procedure.

5. When the procedure has completed, the 350 QX3 will 

emit a “happy” tone and the LED will display green 
indicating the calibration was successful. If it emits a 
“sad” tone and the LED displays solid red, repeat the 
calibration procedure. 

Pressure Sensor Calibration 

The pressure sensor is calibrated at the factory on the 
350 QX3. Recalibration should only be necessary if you 
replace the sensor.  
1. Place the 350 QX3 in a cold area. Allow it to remain 

in the cold for 30 minutes or more. 

2. Bring the 350 QX3 out of the cold and into a warm 

area. The greater the difference in temperature 
between the cold and warm areas, the more accurate 
the calibration will be.

3. Ensure your transmitter is off and then connect a 

fl ight battery to the 350 QX3Power the 350 QX3 ON 
and let it initialize. The status LED will remain off.

4. Hold the 350 QX3 upside down until the status LED 

fl ashes blue, indicating it has entered bind mode.

5. Set the quadcopter back upright.
6. Bind your transmitter to the 350QX3 with the rudder 

stick fully to the right. The LED will blink red and blue 
rapidly. Leave the aircraft and transmitter powered 
on and allow the aircraft to warm up for 10 minutes. 
Do not move the aircraft during this time.

7. After 10 minutes the motors on the aircraft will beep 

to indicate the calibration is complete. Power off the 
aircraft and then your transmitter. 

If the 350 QX3 displays the failed calibration code, power 
off the aircraft and then begin the pressure calibration 
procedure again.
