How to make celibration for drone?

How important is drone calibration?

Inaccurate calibration will greatly increase the risk of drone crash! ! In fact, many drone crashes are caused by improper level calibration, compass calibration, and ESC calibration before flight.

This article explains in detail how to operate it correctly.

Horizontal calibration


The operation steps of horizontal calibration are as follows:
Step 1. Place the aircraft on a level ground and ensure that the fuselage is level and vibration-free.

Step 2. Perform the outer eight-character locking action on the remote control and keep it for more than 10 seconds until the status indicator light starts to flash alternately in blue and green.

Step 3. Release the remote control lever and keep the throttle at the lowest level. After about 10 seconds, the status indicator changed to a single flashing blue indicator, and about 15 seconds later, the status indicator flashed normally.

The operation diagram is shown in the figure below:



Note: If in the future flight process, after the attitude mode takes off, the aircraft still has serious sideways, it is recommended to re-calibrate the level.

Compass calibration


The operation steps of compass calibration are as follows:

Step 1. Push the throttle stick to the lowest position.

Step 2. Quickly switch the 5-channel switch of the remote control between the lowest position and the highest position for about 6~10 times, until the blue status indicator light is on.

Step 3. Place the nose of the aircraft forward and horizontally, and then slowly rotate it clockwise at least one turn until the status indicator light is steady green.

Step 4. Turn the aircraft nose down and the fuselage vertical, and then slowly rotate it clockwise at least one turn until the status indicator light stays on for 4 seconds.

If the status indicator turns red for 4 seconds, it means the calibration has failed. Repeat steps 2 to 4 until the operation is successful.

The operation diagram is shown in the figure below:



ESC calibration


Step 1. Push the throttle stick to the highest position.  At this time, the status indicator indicates the current GPS status and flight mode.

Step 2. Switch the 5-channel switch between the lowest position and the highest position for about 6~10 times until the status indicator light turns red.

Step 3. Keep the throttle position unchanged, disconnect the main power supply, and then re-energize.  Note: If your power and flight control are powered separately, when the calibration ESC is re-powered, you need to cut off the power, then the flight control, then the flight control, and finally the power.

Step 4. About 0.5 seconds after power on, you will hear the motor "di-di-" twice, and then pull the throttle stick to the lowest position within 2 seconds. At this time, after the status indicator light flashes alternately in red and blue, it enters the normal indication.

The operation diagram is shown in the figure below:



After the ESC is successfully calibrated, the motors will rotate in sequence when unlocked, otherwise, recalibration is required.

Calibration before each take-off is a very good habit. Only if you are willing to spend time and energy on the drone, reduce the occurrence of crashes.
