Plug in the power to the quad and push the rudder stick to the left for 5 sec until it beeps.
00:25with the front of the quad facing away and lvl, tilt the quad away from you 90 degree, tilt toward you 90 degree, tilt toward the left 90 degree and then tilt toward your right 90 degrees. You will hear a beep after the last tilt.
00:40 Repeat the process once again (tilt away 90, tilt toward you 90, tilt to the left and tilt to the right) and you will hear a two beep.
00:50 repeat the tilt process one last time and you will hear a 3 beep followed by a long beep.
1:00 when you hear the 3 beep plus the long beep, it tells you the process has been completed successfully.
1:15 Lets repeat the whole process one more time. hold the rudder stick to the left for 5 sec
1:20 1st set of tilt and beeps
1:30 2nd set of tilt and 2 beeps
1:38: 3rd set of tilt and 3 beeps followed by long beep.
1:50 now, the calibration is completed once again. now, we should finish it by activating it. (looks like he pushed rudder to the right) when red LED comes on it is completed. Even if you turn the quad, it should hold the calibration.
2:09 Now, if we move the quad to the corner of the office, we will not get a good lock due to it being a poor magnetic location. (editor's comment: probably due to presence of metal or magnetic field)
2:20 even if we take magnetic compass, it read false north in this corner of the office.
2:30 so, when we move the quad back to original location, the magnetometer start to work properly once again.
2:40 In practice, you really should not do the calibration indoor, rather you should find a nice open clear field to do it. where there is no poor magnetic influence.
3:02 so, do you need to do calibration every time you move? well, it depends on the situation. While it is not needed everytime, you should consider recalibrating if you goto a new location.
