DJI Mini 4 Pro – Calibration of IMU, Compass, Gimbal, and Remote Control

This is a step-by-step guide to some best practices to be performed occasionally on the DJI Mini 4 Pro to maintain proper in-flight performance and avoid accidents. I will show how, when, and why to calibrate the IMU, compass, gimbal, and remote controller

How to Calibrate the IMU


The IMU affects the behavior of the aircraft in flight, it is, therefore, important for the safety of your unit

It utilizes several components of the aircraft, like the gyroscope, the barometer, and the accelerometer to keep the drone flying in a smooth, stable, and balanced way

If the aircraft has an unexpected flight behavior, cannot fly in a straight line, doesn’t maintain the altitude, drifts while hovering, or doesn’t respond appropriately to the sticks of the remote control, the first thing to do is to calibrate the IMU and the compass

Another occasion for calibration is when DJI Fly app prompts to do so with an on-screen message

The calibration is also suggested after traveling more than 50 miles, after big elevation changes, for example during a trip to the mountains, or when the temperature is drastically different from usual

A few times while traveling I have experienced very wild behavior of the aircraft, and indeed calibrating the IMU fixed the issue


Choose an area far from metal and free from interference. Place the Mini 4 Pro on a horizontal, level, and perfectly flat surface

Make sure to have at least 50% battery time both in the drone and the remote controller

DJI Mini 4 Pro - IMU Calibrate in the Safety tab of Settings

In the Safety tab of Settings, we scroll down until we find IMU Normal, and hit Calibrate. We are presented with a screen that guides us to the steps needed for the calibration

We are asked to position the drone with folded wings in five different positions

Position 1 – laterally with the camera facing to the left, we can then hit the Start button at the bottom of the screen. To the right of the screen, a ring shows the progress of the first step

Position 2 – with the drone sitting on the left side, with the power switch facing us and the camera to the left

Position 3 – with the drone on its back and the camera facing to the right

Position 4 – with the drone on its right side and the camera facing to the right

Position 5 – with the drone standing on the back, showing us the right side

Finally, we place the drone in the first position and the aircraft will restart. It is a bit like doing yoga

This short video shows the different positions, it should help to get them correctly

At the end, a message will confirm the outcome. If the calibration has failed, move to drone to a different location far from metal and magnetic interference, making sure that the surface is perfectly flat, and try again

How to Calibrate the Compass


The compass keeps track of the drone’s position and home point. If it is not calibrated properly, the drone might fly erratically or crash

It also plays an important role in the case of a Return to Home

Like in the case of the IMU, the compass calibration has to be performed in case of unusual flight behavior or when prompted on the screen


The procedure is very simple. We find the option for the calibration of the Compass just above the one for the calibration of the IMU in the tab Safety of the Settings

We choose an area free from metal and objects with an electrical charge, the calibration might fail in low light

The aircraft must be held at a height of about 1.5 meters, from the ground, about 5 feet, which is for most people at shoulder height

After hitting the Start button, simply follow the instructions on the screen: first, rotate the drone 360 degrees horizontally, then turn it to a vertical position and do the same

The maneuver can be accomplished by simply rotating the hand holding the aircraft, no need to perform complex circular dances or other dangerous acrobatics

A prompt on the screen will show the result, in case of failure try again further away from interferences.

How to Calibrate the Gimbal


Unlike the IMU and the compass, the gimbal calibration doesn’t impact the flight behavior but acts upon the alignment of the camera

Any time it is switched on the Mini 3 operates a sort of basic gimbal calibration

The reason why we want to proceed to a gimbal calibration is in most cases when the horizon is uneven, often after a small crash or a hard landing

In Settings, we go to the Control tab and scroll down until we find Gimbal Calibration, there is a choice between Auto and Manual

For Auto calibration, the drone must be placed on a level surface, as for the IMU, but this time with open wings

The calibration starts immediately after hitting the Auto button. The camera moves horizontally and then vertically for a few seconds and the trick is done

A Manual calibration is generally performed while flying, if we notice that the horizon is uneven, we hit the button below Auto and we are presented with two values that we can modify

The first one is the rotation of the camera, the second is the horizontal alignment

How to Calibrate the Remote Controller


The remote controller contains a compass to detect its position. It works like the one of the aircraft

On some rare occasions, we may be prompted to calibrate the controller itself by a message on the upper left part of the screen of the RC controller


Video by Vicvideopic

The procedure for calibration is very simple and it is explained on the screen

It is very similar to the one for the compass, by simply rotating the controller horizontally and then vertically

With the RC 2 controller with the built-in screen, it is possible to summon the calibration of the controller

To do that, we scroll down twice on the screen to reach the menu window. We hit the gear icon on the top right of the screen and then we choose Compass Calibration
