Master AirscrewStealth Propellers for Hubsan Zino Mini Pro & SE - Black, 4 propellers in Set

I am leaving this review primarily to help others understand a few things about these that are good to know going in IF it's your first time owning and/or modifying a drone, like this was for me. I'll preface by saying that I have NOT yet gone on a full flight - just a quick indoor hover test flight, as it's too cold where I am right now to full send it. I'll update later on (if I remember) with any additional observations.First, I want to dispel the topic that hung me up the most with these. One other reviewer noted that the screws are too short, and yes, they are a tiny bit shorter than the factory screws (at least, they were in my case). I was very hesitant about this, especially once I ordered the kit and was able to confirm that, indeed, they're shorter screws. They're only about 2 threads shorter, however, and come with threadlocker. After discussing with the EXO support however, my concerns and hesitations were assuaged, and upon installation, they absolutely hold tight enough. I have no concerns that they'll start loosening up from the vibrations at any point, but part of your pre-flight checklist should be double checking that they're tight before every flight anyway.The thing about these screws is that they're NOT intended to hold the blade tight. The blade should be able to rotate freely around the post they sit on, and in this, they work just fine despite being a tad shorter. If you still have concerns however, you can always reuse the factory screws ONLY if you reapply some more threadlocker to them. I suspect that, since these are a little thicker and denser of a material, the shorter screw was a deliberate choice to compensate for the weight balance in the rotational dynamic, but I could be wrong.Second, I wanted to confirm what other reviewers noted about there being a little excess material from the manufacturing process. I did encounter this, though mine wasn't too bad. A couple quick scrapes with a fine-cut file (equivalent to about 450 grit sandpaper) was all I needed to deburr a couple small bits and it was all good. Hardly a reason not to purchase, in my opinion.Now, again, I haven't done a full flight, but did do a quick hover test indoors to check the balance and see if the slightly shorter screws would loosen up at all from the drone simply running. My first impressions are very optimistic. I don't have a frame of reference for the reduction in sound, as I never powered up indoors with the factory props, but it did /seem/ a little quieter, or at the very least, a lower pitch.Obviously, I couldn't ascend very far, but the tone/pitch for a brief and mild ascent rate definitely seemed less...screechy, if that makes sense. Once it warms up and I can take it for a full flight outdoors, where I have an actual frame of reference for the sound under higher power, then I can provide a more accurate analysis.I also cannot comment on any improvement to battery range, as I wasn't about to keep it hovering in this small space for the 40+ minutes this battery lasts. Besides, I'm sure hovering at idle would, by definition, "extend" the battery range due to it not being under full power for any extended period and therefore using battery faster, so that'd be an inaccurate representation anyway.Once I get it outdoors for a full flight, I'll be able to gauge any improvement to battery range under normal use much better; however, since the advertised improvement is only ~1 minute, which is heavily dependent upon many other factors (air temp, hover time vs. full power cruise time, whether or not you're recording, etc.) I'm not putting too much stock in this particular perk.Lastly, I wanted to comment on the responsiveness. It could just be a phantom/placebo observation, but in this hover test, of course I didn't /just/ hover - I did ascend a little and nudge forwards, backwards, and side to side, and it definitely /seemed/ like a softer/shorter flick of the control achieved the same corresponding movement of a longer flick of the control with the factory props.That, again, is kind of hard to quantify without a prior frame of reference for an indoor flight, but it definitely seemed like I could maneuver with a little more precision using softer motions on the controls, and the descent smoothness (from all of about 6 feet) seemed less choppy than the factory props, but again, kind of hard to quantify without the right frame of reference.All in all, so far, I'm impressed with the overall quality of this product, and am very optimistic for how it will perform on a full flight. Even if the noise reduction, improved movement responsiveness, and battery range increase are all effectively placebo effect, then if nothing else, the red color looks slick and will theoretically be at least a tiny bit more visible at a distance. That is a positive on its own because this drone is tiny and starts getting hard to keep eyes on once it gets only a couple hundred feet up and/or out, so if the brighter prop color can improve that visibility even a little bit, it's worth the cost and effort to swap out, with or without the other benefits actually being realized.

Pretty tough to find replacement props for the Hubsan Zino Mini Pro and Mini SE in the US through Amazon Prime. There's a theory on some forums that the stock props will eventually fail (after 6-12 months of flying) and cause a crash, so I've been looking for some more robust props as a replacement. These seem to fit the bill and fit well. I took a test flight and they are noticeably quieter, while the ZMP remains stable. The only downsides appear to be a bit of sloppy manufacturing--as others have mentioned, there are some plastic burrs in the center prop attachment point that can be sanded away, which may improve balance. In addition, because the props are made of a bit thicker plastic, they no longer stow away nicely when you fold the drone--they stick out a bit, or you have to force them into the folded position. I'm ok with these tradeoffs as long as they have better durability. My last test will be to check and see if there are any new video vibrations introduced due to unbalanced props or the burrs causing some vibration. Will report back if that is the case, but so far they look like an improvement over the stock props.

excellent value for the money, an upgrade from the OEM props

Works on my exo pro.

Keep it up, the propellers turned out really nice. I need a 3ft fpv cable for the hubsan zino.if you have it let me know.

Ya lo he usado en otros drones es muy bueno

Didn't fit

Questo colore colore mi permette di vedere il drone più facilmente

Nice and easy to put on , lovely colour and does what says on the tin excellent quality and product

The media could not be loaded.  Achat pour la couleur des pales oranges,le bruit moins aigu donc réduction du niveau sonore,voir le temps de vols qui doit augmenter.Voir la stabilité du drone à l'usage.Sinon certains trous de fixation mal ébavurés(prendre du papier de verre grain très fin pour enlever le surplus de plastique).Et le prix qui ne vaut pas la finition de fabrication.

Me gustó la rapidez de entrega , lo único por poner un pero , cuando comprar un artículo para hubsan zino Mini Pro , el envase debería ser para hubsan zino Mini Pro , no para el SEGRACIAS

I find these better than DJI props and stronger different noise aswell
