Recent everns have me needing to buy a spare set of props.  I can get a set of DJI branded props at Bestbuy for $12.99.  I am wondering if any of you have found any 'better' third party propellors.  I went through what was on Amazon and 1) they seem to be from the same manufacteror and 2) there are a lot of reports of them failing by hitting the body and/or crashing.  Are you guys aware of any upgraded third party props?
Also, what's the frequency you are changing propellers at?  I had the dread EOC decent problem and have seen speculation that this is because the props are 'worn' out, no longer in the right shape to give full lift etc.  Mine had not been changed since December when I got the MM, and it does sound reasonable that plastic fatigue could be a factor.

If there were more efficient and resistant propellers I don't see the problem. What if they were the ones causing the ESC errors?

You're right that stock props look paper thin and even landing in to the grass can probably lead to serious damage. For me stock props are the way at the moment as you don't need to change them all if you damage one blade. I have no experience with third party props. But I'm looking forward if some proven manufacturer comes with real upgrade (like slightly heavier but more durable).

I honestly don't think props can be at fault for the uncommanded descent issues. My reasoning:
  • Experiments by different people here on the forum are not reliable. Some people concluded it was the props because the issue didn't happen again after replacing the props. Some people concluded it was the firmware because they downgraded to a previous firmware and it didn't happen again (while others had the issue on that exact previous firmware). Others concluded it was the battery because they swapped with a different battery and it didn't happen again. Seems like the issue is random enough that it's causing a lot of "false positive" for people doing different tests
  • In a lot of the uncommanded descends here, the craft started descending quite rapidly. An incremental fatigue in the plastic causing the props for some reason to be less and less efficient would not happen this suddenly unless it totally fails. You would see the craft having problems climbing before having problems maintaing altitude and as far as I know, this never happened.
  • There were those lucky enough to be quite low at the moment of the descend and to get away just with the craft bouncing of the ground. They then had no issue flying it again with the same set of props. I don't see how plastic fatigue can cause props to fail like this and then be ok again.

If you 'damage a blade' ... change it.

No doubt about that, but heaving third party props you need third party spare blades and that makes my Fly more combo spares useless...

I once saw a youtube video, where someone had aftermarket props. He said they were more silent, but they were even faster destroyed by normal flying than the original ones.. The props started to fringe at the ends very fast. But I am unable to find this video.. Most other people would reommend masterairscrew, but there arent one for the MM (yet).

Master air screw is working on the mini’s now they have quality propellers all others fail fast they don’t seat like the originals do. Steve Coutts put the video out about the propellers, search on YouTube! You void the warranty if you install 3rd party accessories!

Hey,

Some of my props have minor damage at the tips (from me hitting a wall when I just got the drone).. It's never been a problem even flying at 500 meters in a bit of wind.
The drone can lift it self twice (it can almost carry a 330ml can of beer - well .. had to try)  so I can't see a single prop being damaged would make it drop out of the sky.

  • Totally agree, it’s just the YouTube fanboys pushing prop changes, too afraid they’ll loose there next free drone.  My first set of props were trashed and my Mini still flew great, 128 flight hours later I’m getting prop strike with new props! Batch issue? Mini arms degrade over time? Waiting to see if DJI action any changes

    The ones I bought.

    They have worked perfectly for me. I'm currently on the second set (yellow). The Red ones are really pretty in flight.

    Some reported of being heavier as a bonus, I see it more as a plastic deficit, where DJI uses the best material to ensure structural resiliency and maximum lightness. Also they might not have the same tolerances, the pivot screw hole fit is quite critical for how the propeller manages to stay level during steep climbing or descending.

    Although obvious third-party propellers are justified only if they offer better performance or the same at a very low price.

    However, the variety of the offer is useful to have a better product.
    I have many doubts about the guarantee, so they don't answer.

    Hi. Thank you for reaching out to DJI Forum. With regards to this concern. DJI does not recommend to use any third party accessories. We cannot guarantee the stability and compatibility of the said accessory during flight. This may lead to an incident, that can or will void the warranty. Please visit our official DJI Online Store to ensure that the items purchased are genuine DJI products. Thank you and have a safe flight always.

    Is it confirmed info about Master air screw? Their props look very solid and precise, and silencing Mini potentialy even more would be great too...

    The flight controller will compensate for damage/misalignment of the props, and your MM might still fly well (enough). But unbalanced props, especially on a small AC like the MM, would introduce unwanted vibrations. I would personally replace them. Besides, DJI props are fairly priced, don't see the reason to experiment with alternatives unless proven to be better.

    Third party props can be dodgy but I don’t have much faith in stock props ether. One screw came with the combo had bent thread. If I tried to tighten it down I could have damaged the motor casing.

    You don't trust third party products because Dji sent you damaged goods? Rigorous reasoning

    Australia got stock this January. China always had plenty. I had no issue buying them off authorized retailers online. Strange enough I visited a number of DJI dealers in China and none of them had stock last year.

    Well, because DJI props, although reasonably priced, I can not find any place that charges less than 100% of the cost of the props for shipping.  Buying from DJI in US$ is no different, plus you will probably get nailed at the border if you don't live in the US.

    If anybody knows of a Canadian seller for the props that does not over charge for shipping ....

    Losing a propeller in flight can also happen with an original if it is fixed incorrectly, blaming a non-Dji product without any proof seems incorrect to me.

    This is just the latest complaint... there's already several of them including in this very forum of people complaining about loose fit, questioning material quality.... there's all kind of problems related to non-DJI propellers.

    If I'd really like to skimp on something or personalize... that would just be anything but the propellers. Would you mount a set of GoodRide tires on a Ferrari 458 Italia !?  Yest they may look fancy... but you're gonna suspend your precious piece of "equipment" on cheap tires... your life depends on that, same for the little unmanned aircraft. I wouldn't really go for non-DJI props since the original are not even that expensive by DJI standards.

    You have a very strange concept of proof, proving the cause is very difficult.
    If there were leaks of original propellers, would it be Dji's fault or the faulty assembly?

    Even Amazon reviews reflect that view on non DJI props.
    Questioning my concept of proof is not my problem, if you're sure of your idea you have nothing to fear. Everybody can judge on their own.
