    Just received my order for these Carbon Fiber jobs from an eBay seller.
    Item # 251940172735

    First 2 things that I notice:
    #1 - Props are REALLY STIFF! Not bendy like the OEM props (good or bad?).
    #2 - They have an aluminum threaded hub. Thought this might really be a big + since plastic threads can get stripped out if you simply use them too much (taking your props off and on).

    Additionally, they feel somewhat heavier; haven't weighed them yet, but will.

    Anyone have any experience with these? Good or bad?

    BTW, the avatar that I just posted was a pic that I took this winter down on Sanibel Island. These 3 cheerleaders were "practicing" right in front of us!! WooHoo!

    It's not a good idea to use non-OEM props. They might unwind and fly off mid-flight due to the active braking feature :(

    All of these props are okay to use:

    Those are not P3 props. There was a hub material change to the composite (plastic) for greater friction to keep them from loosening due to the P3 having active braking.

    Use with caution.

    I thought that same thing, so I'm going to do some "careful/low-level" flight tests to see if they loosen. I will check torque settings before & after. The only way I could envision them loosening is because of the aluminum hubs. The plastic hub "may" act somewhat as a locktite-of-sorts, inhibiting the loosening; we'll see.

    People fail to realize that unlike most aircraft in the past, these quads use closed-loop control systems which have been tuned for the most efficient operation.
    This includes hardware.

    Not sure where the whole mindset that CF is better for everything came about. OK it's lighter and stronger than many other materials but that is not always a plus.

    I have P2 CF deja vu. But this time, with braking ESCs, the odds of catastrophe are much higher.

    After market carbon fiber props may look cool. But... They don't work. You can evaluate at your own risk. The P3 is a finely tuned propulsion system. Only use DJI props.

    I have been fore-warned; thanks. Appreciate the input; I think I will just send them back!

    One reason that I was looking for a stronger hub material was because of the potential thread-galling plastic threads, but I see the point with the active-braking feature.

    Just google image search "carbon fiber prop injury". Should be reason enough.

    You want the plastic threads! They are composite and are designed to stay tight under active braking.

    As mentioned CF is just marketing. Also, the ones you have are not for the P3. What "low level" flying won't result in damage.

    I wonder whether some superglue would hold them in place, though

    I don't get this whole carbon fibre props thing.

    You don't buy a Ferrari and run cheapo crappy tyres on it.

    Hi Kleenax

    Send the props back, but post the pics of your cheerleaders. Much more exciting.

    Eagerly awaiting your reply
