Most people don’r realise that the coss head screws on precision products made in China, Japan, Korea etc aren’t Phillips. If you use PH scewdrivers your running the risk of graunching the screw heads.
The cross head screws used on products from this part of the world are JIS heads (Japan Industry Standard). They look similar to Phillips but the angles and dimensions are slightly different.
Only use JIS crosshead screwdrivers on your DJI Drones.
Here’s great set of miniature screwdrivers for drones, cameras etc. that I use:
I have a distinct feeling that I bought this exact set at Yodobashi camera in Tokyo when I was there last time, because my watch bracelet broke and I needed to fix it.
