Master Airscrew Super Stealth Propellers for DJI Mini 4 Pro & Mini 3 Pro - Blue, 4 propellers in Set

These replacement propellers are excellent! They are slightly larger than the originals. I have noticed these are quieter, just as stated, and that has enabled me to fly and cause less distraction to people and animals. The manoeuvrability is better due to the larger propellers but it can also make it a little bit more tricky in windy conditions and gusts, but that is a trade off that I am happy with. The flights speeds are the same and breaking is a lot better due to the larger surface area. The quality is excellent and installation is the same as the originals. Red propellers are also a bonus and have deterred seagulls that used to attack my Mini 4 Pro

Purchased these following a YouTube clip showing the improvement to the drones flight (noise, flight time etc). These were a direct replacement to the original and make the drone look different from the default. After testing the drone is alot quieter and the flight time was improved by a couple of minutes which may not seem like much but makes a difference. They also make the drone slightly lighter which would benefit anyone looking to use the larger battery and keep the weight below the 250g. Highly recommend .

Widely advertised too be quieter and give added distance. I can’t comment on the distance, doubt I will fly it anywhere near its limits. It is quieter, but I had added a drop of very fine motor oil used for models on the engine motor as well. Standing next to it it was almost silent, very quiet. I found no instructions on my packet inside or out, so had to guess which prop went where, This is poor , surely an imprinted FR or BL on a blade would help a Lot. The shape of the propeller is different to DJI,s so difficult to judge. Please note hundreds of problems with people stripping the screw head. DJI supplied screwdriver is WRONG, it’s a Philips head. The screw is Japanese. Looks almost identical, but the Japanese screwdriver has a slightly longer / narrower head which sits deeper into the slot so doesn’t slip like the Philips, which doesn’t sit so deeply. How can DJI get this so wrong.? Look on you tube at the number of comments about this problem.

Very disappointed with the quality. I only bought these to visually enhance my drone. I expected OEM quality for the price difference, these are shocking! Burrs all over the edges, which will disrupt air flow. Visible injection casting marks. They seem verry flimsy and I'm considering returning them.

Now the drone flies without buzzing.

Awesome. Very quiet and a lot more responsive than the OEM … very happy

I upgraded my Mini 3 pro props from the stealth to these. Both sets of props hovered at 83db and the only difference was a slight change in pitch. Unless you need new ones, don't bother buying these thinking the drone will be quieter. I doubt you will notice much difference. Such a shame

Hard wearing - very good, I have crashed them a couple of times and are still good enough to fly

UPDATE: They are noisier up between 15mtrs to 30mtrs, loud buzzing bees whereas the original ones is quieter! This batch of Master Airscrews is so screwed! I decided to get them in orange for my Mini 4 Pro this time just like what I had for my Mavic Pro 6yrs ago. Always appreciate their quality control back then for smooth finish and perfect all round. It even came in a box. However for Mini 4 Pro, I cannot say the same. It is quite upsetting in terms of its quality. Many burrs on the propellers which ought to be sorted in production line before putting up for sale. Bought two sets and both are the same. I am not so sure if this is even made in the USA.

Altijd prima propellers van Master Airscrew.

more silent work vs stock

Solo chi ha problemi di udito può dire che queste eliche non abbiano una evidente efficacia nella riduzione del rumore complessivo percepito. La riduzione del rumore consistente soprattutto nelle frequenze alte che sono quelle molto fastidiose, questo però ha effetto sulla percezione complessiva e rende davvero più silenzioso il Mini 4 Pro. Ripeto, la differenza è evidente rispetto le eliche originali. Il comportamento di volo del drone (per il momento) non ha alcun cambiamento sostanziale, anzi, mi è parso che con queste eliche abbia dei movimenti più fluidi, meno “scattosi”, ma ancora le ho usate poco e non posso sbilanciarmi troppo in merito. Sinceramente, non so se a lungo termine possano dare altri problemi, essendo comunque eliche non progettate dal costruttore originario del drone, questo è un rischio che bisogna mettere in preventivo. Se avete necessità di fare qualche ripresa in ambienti chiusi, per qualche evento o per qualche festa in sale ricevimenti, allora posso dirvi che sono ideali. All’aperto non sono indispensabili se non per le colorazioni sceniche, però se si vola in zone urbane con presenza di persone, sono comunque molto efficaci per mantenere una rumorosità più contenuta e per attirare meno l’attenzione dei soliti curiosi. Sono soddisfatto per il Mini 4 Pro, mi dispiace che queste eliche per il modello DJI Mavic Air abbiano un costo molto elevato, altrimenti avrei provato anche un test su quel tipo di drone che è di suo già molto rumoroso. Dovrebbero ribassare il prezzo, le comprerei. Acquisto consigliato, ma ricordate di fare attenzione quando le usate perché, ovviamente, in caso di crash, la DJI non vi riconoscerebbe né la garanzia, né la Care Refresh. Questa, per me è una assurdità, perché potevano progettarle loro stessi questo tipo di eliche, penso che abbiano le capacità per farlo anche loro.

I do feel they produce less noise at a lower frequency. However you'll need to spend some time with some high grit sand paper removing the flash from the injection process because the edges are pretty ragged. Also, my DJI M4P is 1.72g heavier with these props so weigh your drone to see if that's gonna be a deal breaker. An OEM blade weighs 0.88g, these weigh 1.095g. I feel the flight time has slightly increased. The supplied screws are so tight I was afraid to force them in. I decided to use the OEM screws.
