I’ve seen a few posts about the problems that people are having with changing propeller blades using the free screwdriver “kindly” provided by DJI. Further investigation led me to YouTube where a guy was performing an emergency prop change on a rocky beach in Spain.
Apparently, the screws that DJI use to secure the propeller blades (at least in the Mini 3 Pro) look like Phillips but are in fact “JIS” standard which have a different profile where the screw “cross” meets. This is the reason that screw heads get chewed up when using a Phillips driver, even of the correct size.
So I’ve ordered a set of JIS-standard mini screwdrivers off Amazon for £14 and will post an update here if they’re satisfactory. Hope this helps!
The JIS screwdriver set arrived from Amazon and it seems to actually fit the propeller screws: the feel of the bit in the screw is very different. I’ve included some pix which will hopefully show the difference.
The screws come pre-applied, that’s dried and OK. Don’t add wet/fresh loc-tite to props, ever. I guess you could drop a little on a screw and let it dry for a few days, but I personally wouldn’t risk it.
On our FPV drones we use nylon locked nuts, and they don’t come lose (well often), just use loctite on the frame screws.
I need to change couple of propellers on my mini pro 4 drone … but the skewdriver that comes with it is useless
Can someone please tell me what type of skewdriver I need to change the propellors. Thank you. Steve …
