Compass Calibration Steps
Compass Calibration
Pressure Sensor Calibration
Accelerometer Calibration
The Flight Controller on the 350 QX 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 QX to get accurate compass
measurements. It is possible, however, that your compass may need to be cali-
brated if it is exposed to strong magnetic fi elds.
Compass calibration procedure:
1. Go to an open space outdoors away from metal. Take a conventional com-
pass 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
QX. 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.
3. Once the blue light begins fl ashing, bind with yaw stick left. The 350 QX LED
will slowly fl ash between red and green for 5 seconds.
4. Put the 350 QX 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 QX should still be
blinking rapidly when you fi nish. Hold the aircraft still until it stops blinking rap-
idly. If successful, the 350 QX will beep a positive confi rmation and then restart
itself. If unsuccessful, the 350 QX displays the failed calibration code, a solid
white LED. If the 350 QX 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 QX. Recalibration
should only be necessary if you replace the sensor.
1. Place the 350 QX in a cold area. Allow it to remain in the cold for 30 minutes
or more.
2. Bring the 350 QX 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 QX
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 QX 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 QX 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 Stability Mode or Smart Mode. The quadcopter
will fl y in Stability 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. Use trims to adjust roll/pitch so the quadcopter does not drift left/right and
forward/back.
6. Activate the accelerometer calibration mode by changing the fl ight mode
switch into Agility Mode. The vehicle will still fl y in Stability Mode. The LED
will start fl ashing quickly (red, green, blue).
7. Fly steadily for 10–30 seconds. The LED will fl ash slowly when data
collection is done.
8. Land the quadcopter and stop the propellers by lowering the throttle and
throttle trim.
IMPORTANT:
The calibrated values are not yet permanently stored. Do not turn
off the quadcopter.
9. Center the trims on the transmitter. Start the motors and verify the
quadcopter fl ies without drifting.
10. Land the quadcopter and stop the motors by lowering the throttle and
throttle trim.
11. Save the calibration by moving the rudder stick quickly left, right, left, right.
Values are saved when you hear a rapid triple tone twice.
12. Turn off the quadcopter.
13. 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.
