Compass Calibration Steps
Compass Calibration
Pressure Sensor Calibration
Accelerometer Calibration
The Flight Controller on the 350 QX2 has automatic magnetic declination calibra-
tion, so you will not have to worry about looking up the magnetic declination at your
location and changing settings on your 350 QX2 to get accurate compass measure-
ments. The status LED blinks orange if the compass senses a magnet or metal object
nearby. A random orange fl ash of the LED is considered normal, and not cause for
compass calibration. When the Status LED blinks a consistent pattern of orange,
compass calibration should be performed using the procedure below.
Compass calibration procedure:
1. Go to an open space outdoors away from metal. Take a conventional compass
with you to ensure you know the direction of north.
2. Ensure your transmitter is off and then connect a fl ight battery to the 350 QX2.
Power the aircraft on. Wait fi ve seconds and then the blue LED will begin fl ash-
ing rapidly, signaling the aircraft is initialized and ready to bind.
3. Once the blue light begins fl ashing, bind with yaw stick left. The 350 QX2 LED
will slowly fl ash between red and green for 5 seconds.
4. Put the 350 QX2 fl at in your hands and face north. After 5 seconds of slow
fl ashing, the quad will start fl ashing rapidly. The quad is now collecting data to
be used for the calibration.
5. Slowly rotate the quad 360 degrees about the east-west axis (“fl ip” the aircraft
either forward or backward) until it is fl at in your hands again.
6. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing north-west.
7. Slowly rotate the quad 360 degrees about the east-west axis,
(“fl ip” the aircraft diagonally either direction) until it is fl at in your hands again.
8. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing west.
9. Slowly rotate the quad 360 degrees about the east-west axis
(“fl ip” the quad sideways either direction) until it is fl at in your hands again.
10. Continue facing north and yaw the quad 45 degrees left so the quad is now
facing south-west.
11. Slowly rotate the quad 360 degrees about the east-west axis
(“fl ip” the aircraft diagonally either direction) until it is fl at in your hands again.
You have 30 seconds to complete the procedure. The 350 QX2 should still be blinking
rapidly when you fi nish. Hold the aircraft still until it stops blinking rapidly. If success-
ful, the 350 QX2 will beep a positive confi rmation and then restart itself.
If unsuccessful, the 350 QX2 displays the failed calibration code, a solid white LED.
If the 350 QX2 displays this error code, power off the aircraft and then begin the
calibration procedure again.
The pressure sensor is calibrated at the factory on the 350 QX2. Recalibration
should only be necessary if you replace the sensor.
1. Place the 350 QX2 in a cold area. Allow it to remain in the cold for 30 minutes
or more.
2. Bring the 350 QX2 out of the cold and into a warm area. The greater the differ-
ence 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 QX2 and power the aircraft on. Wait fi ve seconds and then the blue LED will
begin fl ashing rapidly, signaling the aircraft is initialized and ready to bind.
4. Once the blue light begins fl ashing, bind with yaw stick right. The
350 QX2 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.
5. 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 QX2 displays the failed calibration code, power off the aircraft and then
begin the pressure calibration procedure again.
To calibrate the accelerometer, the quadcopter needs to fl y for 20 seconds while
being level. This allows the accelerometer readings to be averaged and stored in
memory.
Use the following procedure to calibrate the accelerometer:
1. Power on the quadcopter with the transmitter off to enter bind mode.
2. Turn on the transmitter while holding the elevator stick back and pressing
the bind switch.
3. Set the fl ight mode switch to AP Mode or Smart Mode. The quadcopter will
fl y in AP Mode no matter which position is selected.
4. Start the motors. Fly the quadcopter off the ground. The quadcopter LED will
fl ash slowly (red, green, blue).
5. Activate the accelerometer calibration mode by changing the fl ight mode
switch into Stability Mode. The vehicle will still fl y in AP Mode. The LED will
start fl ashing quickly (red, green, blue).
6. Fly steadily for 10–30 seconds. The LED will fl ash slowly when data
collection is done.
7. Land the quadcopter and stop the propellers by lowering the throttle and
holding the bind button for 1 second.
IMPORTANT:
The calibrated values are not yet permanently stored. Do not turn
off the quadcopter.
8. Start the motors and verify the quadcopter fl ies without drifting.
9. Land the quadcopter and stop the motors by lowering the throttle and
holding the bind button for 1 second.
10. Save the calibration by moving the rudder stick quickly left, right, left, right.
Values are saved when you hear a rapid triple tone twice.
11. Turn off the quadcopter.
12. Confi rm the calibration by powering up the quadcopter and performing a test
fl ight. If the calibration is not correct, start the calibration procedure again.
