What it does
USB connection without Zadig
The program sets up the drone connection itself — service channel only, and the change can be undone with one button.
Gimbal calibration
One-button calibration on Air 3, Air 3S, Mini 5 Pro and Neo 2; Joint Coarse, Linear Hall and advanced calibration on the rest — after motor replacement or a calibration error.
Gimbal motor test
Move each gimbal motor on its own — pitch, roll and yaw — to find grinding, stalls, flex-cable faults or a weak motor before a repair. Mini 3 Pro, Mini 4 Pro and Mini 5 Pro.
Motor test & ESC beep
Spin each propulsion motor on its own at low power and beep each one to identify it. Mini 3 Pro, Mini 4 Pro and Mini 5 Pro. Remove the propellers first.
Fixes Error 40021
Gimbal IMU-data reset — clears Error 40021 (Gimbal IMU) on Mini 2, Mini 3 and Air 2S.
Live telemetry
Gimbal angles and aircraft attitude in real time.
