Replaced the front right arm on my DJI Mavic 2 Pro. A set of plastic tools for opening mobile phones, drones, etc. was purchased. They came in handy when opening the drone. There are SEVERAL screws, they all use the same size screwdriver, but the screws come in different sizes so please keep track of where they came from to reassemble the drone. A thin-tipped soldering iron and fine solder was used to attach the wires to the motherboard. The hand fits perfectly. After that, I had to recalibrate the vision sensors using DJI Assistant 2 For Mavic. Everything works perfectly!
