I have had problems replacing the dji mini4pro propellers so far, especially when screwing in the new propeller, the last bit is so difficult, even in the video here that last bit is cut out in which the screw has reached its end. You also have to be careful that the screw head does not break off, then you are stuck with screw thread in the spindle. Replacing it would be easy but I do not experience that. And that while it is so important to replace it easily and properly.
@@88sabbel The screws should be screwed in with ease. You shouldn’t screw them in forcefully because you might have a hard time getting them back out in the future. There’s no need to keep trying to screw them in further after they’re close to the propeller. And yes, it’s important to make sure that the screws are going in straight and so that they don’t break!! Thanks 👍
Hi, thanks for reaching out. I have a solution which should work. The idea here would be to at first remove the propeller only, and leave the screw in place. By no means should you snap the propeller off the motor, because this can destroy the spindle it sits on. To do this, you’d need to file away at the circular base of the propeller next to the screw. With an electrical file this would take a few seconds, or alternatively you can use a manual file. In any case, it’s very important not to let the filings fall into the motor though. I’d use a vacuum to pick up these filings while removing the propeller. Once you’ve removed the propeller, grab some pliers and grip the screw at the head and you should be able to carefully twist it away, making sure not to damage the spindle. I hope this will work! Please let me know how it went, and if you have any questions I’ll happily answer them. Thanks
I have found the 'screwdriver's' supplied with the DJI Drones totally inadequate for their purpose. I use a small a 'crosshead' screwdriver with interchangeable sizes that give a good fit and the screwdriver has a larger handle. The whole process I carryout with infinite care as the chances of damage by overtightening the screw (cross threading, stripping, head damage, and the torque to apply to overcome the 'threadlock' against not tightening it 'enough' depends on 'operator feel'. Controversially, I only change the propeller that is damaged. The commercial machinery/tooling used to manufacture the Blades would produce identical Blades so how do they 'match' them in pairs? Weigh them or X ray examination not commercially viable so if the other blade when carefully examined looks ok I only replace the damaged Blade. I have found landing on unmown grass my greatest problem I found that if you peg a say 3 foot landing pad too tight over long grass it will form a dome and the drone will slip off when landing.
Hi, this is all very interesting info. The reason I’d recommend replacing both props on the same motor is because if you clip a branch with one, it’s extremely likely the other prop has also hit the branch due to the speed they’re spinning at. The dome shape on the landing pad is interesting too. Thanks 👍
The mini 3 and 4 are the same propellers, but the screws are different. Make sure you use the correct screws. Better off buying the Phillip's PH000 screwdriver, as the one that comes with the drone can damage the screws 😊
Good advice. In addition, the supplied one is so tiny it's difficult to use. I bought the bigger handled one (reviewed onone of my channels) and never regretted it.
Yeah agreed, DJI’s screwdriver is poor quality, but I’ve had no problems with it at all. Admittedly it probably is a bit easier with larger screwdrivers. I’ve just checked and there are different screws for Mini 3 and 4 Pro, but they are compatible with both drones so no worries there. Thanks 👍
All You say is correct. However, likely having a damage and flying I know the drone managed well even with the orange part lost after landing. Yes, no take off in that condition. Placing the screw into the prop and then lovering to the motor is less fiddly. Losing a screw outdoors is not what You want.
Good point. I’ve tried flying with the orange rubber piece missing on one propeller too, and even though there was no visible change, there is definitely more vibration on that arm. This can be bad for the motor and the prop if done over time. Thanks
Get a set of JIS (Japanese Industrial Standard) micro screwdrivers - this is what DJI use, but don’t supply you with the correct screwdriver for them. It is a small but very important detail.
It is best to open out the propellers before starting the motors as it cuts down the vibration and, over time, can stop you from damaging the motors or cracking appearing around the arms 😊
Very clearly explained. I crashed my Mini 3 Pro by flying it sideways into a mass of branches like it’s did. But of a shock as my first crash. I’ve replaced a couple of times but didn’t know about the marked/unmarked arms or about the anti loose gunk on the threads! Nice watch! 🙏👏🫡
I know a lot of people have trouble with the screwdriver included - and, admittedly, it is of pretty bad quality. However, I had no trouble whatsoever with removing the props with DJI’s screwdriver. It can be useful to use a larger one to have more torque. Thanks for pointing that out though.
Hi, Let me ask something about my drone. After falling due to hit a tree about 2 meters, the drone becomes unstable in its position when the propellers are turned on (not in flight condition, just staying on the floor). The drone keeps moving from the origin position. Please tell me whether this is a problem or is it still normal? All propellers have been replaced with original DJI Mini 3 official ones according to the order of propeller strips A and B. IMU, gymbal and compass calibration and refresh of the frameware with the same version have also been done. But still same. The video can be seen here: ua-cam.com/video/OOkrlNZ7GSA/v-deo.htmlsi=iW6jLRR5IeHwi2GC Thank you in advance
Hi. It’s very interesting, and I tried this same test with my Mini 3 Pro. However, even after 3 tests it was not rotating like yours. I also tried to start up the motors with the drone on a sheet of paper, but it was still not rotating. I also tried to weigh down one of the arms but it didn’t change anything. Does this still occur when the drone starts up on a different, rougher surface?
@ thanks for you trials. On the rough surafe, my mini 3 was also trying to rotate but it was not able to move and shifted only about a centimetre. I’m worry to fly this drone. What do You think about the possible cause? Is it propeller problem or the motor? Or maybe drone engine? I plan to bring my mini 3 to dji official service center next month since it still has a guarantee. But i just still confused why this happened
I’m honestly not really sure about the cause to be honest. I thought it might be because of the propeller being bent? But if there’s no effect on flight then it shouldn’t really matter. It would be interesting to hear what DJI says but I don’t think they’ll regard it as a fault.
Good tips❤
@@AboveandbeyondDRONEscotland Thanks!
nice video thanks for the tips
No problem - glad it helped! Thanks for watching.
Nice video!
@CoasterPro817 thank you!
Great tips
Glad you found them useful! 😀

Is threadlock on new replacement screws necessary?
Hi, the thread-lock helps keep the screw in place in the spindle. It serves as an extra feature to keep the propeller system secure!
Hi. It is very difficult to remove the screws. I could not remove 2 screws at all. The openings of the screws are broken. What should I do?

The screwdriver is no good at all. 100%
I do tend to forget the props doing a pre flight check, naughty.
It’s important to check the props before flight!!

Mini3pro and mini4pro have the same propellers and screws.. it the mini3 that has just different screws ..
I did the same bought a ph000 screwdriver.
thanks for the reminder. sometimes we tend to forget to attend to minute details like prop damage.

@takeoffdrones Yes. Of cource vibrations are bad, grinding down anything and everything if it's allowed to go on.

Do not use the screwdriver included to remove propellers. Not a mention of this.

Just use thread lock easy
Yes, the thread lock is a pretty nice feature. It helps the screws be held in place.
