How often do the blades need to be changed?

[bon_foto]

Just got my Mavic Pro and woundering how often do I need to change the blades.

Inspect them carefully for damage prior to each flight. Change them when they are damaged.

What kind of damage is normal?

 

[msinger]

No damage is normal. Other than scuff marks from folding them, they should be as pristine as the day you unwrapped them.

Even small scratches from the grass?

Please post a detailed photo.

I'm very new to this. Sorry about silly question...

I would replace it if i had a spare but keep it as ur back up spare its most definately usable. I doubt that its out of balance becuz of that chip.
If it makes an unusual new sound, flys different or shows any signs of change from normal then its ready to toss. Otherwise ur fine. Forget about it

I believe this small cut is considered damage and shouldn't be used , right?

Don't use that! The crack will spread under flight load and the blade may disintegrate with the imbalance. Your drone will crash if that happens!

 

[Mavic Maniac]

Correct, change that blade.

Both of those blades should be RED X'd, taken out of service at once. The force applied to a blade is in direct relation to how far it is from the tip, the tip being where it is the greatest due to centrifugal force. Cracks or chips anywhere on the blade renders them not safe for flight. Destroy them so you won't grab it be accident when installing the blades. I for one never store or transport the Mavic with the blades installed, I always remove them and place them in a felt bag (the one supplied by DJI is great)

That chipped blade was after my third flight. On that flight there were strong winds and maybe a few rain drops. There was absolutely no accidental touch of the blade to any obstacle and the landing happened to a clear terrain. I am wondering how that small cut happened. Was it the winds, or maybe it was me trying to take out the bird from its leather case it came with (combo box) .....

I would happily use that blade.

Yes it is a bit odd being on the rear of the blade. Almost like it got crushed or snagged somewhere. Like you said it may have got caught in the case. I would replace it but others might not.

I would be interested to hear from others who, have happily flown for long periods trouble free with props that are not "as new". Conversely has anyone had a documented Mavic prop failure in flight who can show us it's condition before hand? ie speak from experience.

My guess could be hitting bugs in the air possibly

I herd every 24 hours you should change them unless you chip the ends a little

Not so sure you're 100% correct with that observation.
Witness this:

 

[C_Greg]

I have flown a real airplane with 6 inches of blade tip broken, and it was bumpy but I landed safely

I would not. the imbalance on the motor bearings and potential for AC loss is not worth it.

Elon Musk commented in the last few weeks about this sort of attitude to aircraft maintenance and why we don't have flying cars yet. people don't understand why aircraft maintenance is so critical, when something breaks inflight it's not just a matter of coasting to the side of the road like it is in your car.
