DJI Mavic Mini Prop Arm Replacement

はじめに

A damaged or malfunctioning prop arm is a common issue caused by crashes or strenuous flight with your DJI Mavic Mini and will put the drone out of commission until resolved. This guide will walk you through the steps to remove and replace any prop arms you may need to fix to get your drone back in the air.

A basic knowledge of soldering is recommended before beginning this repair as several connection on the main board must be removed and re-soldered and major errors in this process could permanently impact the drone. iFixit's guide to soldering is linked here as well as later in the guide if you need to learn or refresh your skills.
