DJI Mini 3 Pro Propeller Question

I broke the front right blade on my drone. I’ve read that it’s best to change all 8 propellers, even if only one needs replacing. Can anyone give me some advice or share their experiences?

Just replace the 2 on that arm. No need to replace the others.

Just replace the 2 for the arm.

Use a good screwdriver that fits perfectly. DJI screws the propellers in tightly, so they can be hard to get out the first time.

Props are meant to be changed often.

If you change one, change them all.

@Donna That’s bad advice. One prop broke so replace all of them? That’s dumb.

@Hugo Sorry, but that is bad, dumb advice.

@Hugo You’re free to (not) maintain your aircraft any way you like.

@Donna Ill maintain my aircraft in a way thats required. Replacing parts on it for no reason does not meet that criteria. You can do whatever you want with yours but dont spread misinformation.

@Donna You will have people stripping their screws for no good reason.

@Donna I think you mean change all (both) on one rotor, to keep it balanced. If the blades are unbalanced, there will be “wobble” which will wear out the rotor faster. Everyone here agrees with this.

The rotors get power independently and the drone will spin each at a different speed to compensate for any differentiation. This is normal. This will happen even with a full set of brand new blades. Therefore replacing blades on a rotor with no bad blades is unnecessary.

I would argue that it’s bad for the drone in some way, but it’s not really, just wasteful. We have enough plastic waste without doing this. I think the downvotes and responses are because you are promoting wastefulness.

@Rodriguez No, I meant all 8.

As I may have mentioned to another responder, you’re free to maintain your drone any way you see fit. But props are consumables and meant to be changed regularly.

Use fresh screws. If they start to strip, back it out and grab another screw. Hold the back of the motor in one hand and use small, controlled quarter turns. Don’t tighten them completely, they’re suppose to have a little wiggle.

It may be important in theory but I have changed one at a time with no issues.
