Mini 4 Pro Complete Repair Guide: Common Issues and Parts
The Mini 4 Pro is one of the most popular sub-249g drones, combining a 3-axis stabilized gimbal, omnidirectional obstacle avoidance, and a compact folding design. Despite its small size, it is a repairable drone with a growing ecosystem of replacement parts. This guide covers the most common repair scenarios.
Gimbal Camera Assembly Issues
Symptom: Black screen, severe gimbal wobble, or cracked camera housing after crash
The Mini 4 Pro gimbal camera is replaced as a complete assembly rather than individual motors. This is the most common post-crash repair.

Diagnostic Approach
Before ordering parts, analyze your flight logs to identify the root cause of any crash. See our guide on reading drone flight logs. After any repair, always perform IMU and compass calibration — see our IMU calibration guide.
