GimbalDoctor
Calibrate DJI drone gimbals after motor replacement or a calibration error — no service account, over USB.
What it does
GimbalDoctor identifies the aircraft, downloads the right service firmware from the server, installs it and prepares the gimbal for calibration with the remote controller. It replaces paid service tools — it works on its own, over a USB cable.
Automatic aircraft identification and firmware selection
Firmware downloaded from the server under license — SHA-256 verified
Guides you step by step through to the controller finish
Supported drones
Models that need service firmware to calibrate the gimbal:
Newer models (Mini 4 Pro, Air 3, Air 3S) calibrate directly over USB — support added on an ongoing basis.
How to install the USB driver
Once per computer. The app has a built-in wizard (the “Install USB driver” button) that launches Zadig.
- 1Connect the drone with a USB cable and power it on.
- 2Click “Install USB driver” in the app.
- 3In Zadig: menu Options → List All Devices.
- 4From the list pick BULK Interface (Interface 4).
- 5On the right set WinUSB and click Replace Driver.
IMPORTANT: do not change RNDIS (Interface 0) or Interface 1 — that is the drone network, the firmware cannot be installed without it.
How to use it
Install the app and the USB driver (once).
Enter your license key.
Connect the drone, click “Calibrate automatically”.
Finish calibration on the controller — at 90% stand the drone upright.
Remove the gimbal guard before calibrating and use a fan — the drone gets hot.
