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

Product Information

The configuration that the facility has gotten patented almost makes the propellers sound more like a rushing breeze rather than high-pitched buzzing — and it does so without sacrificing thrust. I tested a hover to 125' overhead and the M2Z virtually disappeared (Stealthed ) into general ambient sounds, one would have to be hard pressed to note it at above that height as with some other aircraft, and with the zoom capability of my aircraft (And now the MA2) it serves my function to avoid detection of the local "Gun Aficionados" Which is always a plus. Welcome to the Next Generation STEALTH Upgrade Propellers specially designed for the DJI MINI 3 Pro drone.

IMPROVED SOUND PITCH - Stealth Upgrade propellers provide less annoying sound pitch during all phases of the flight. I have flown my Mavic approximately 50ft above and 25ft away from groups and observed nobody looking up or noticing the small drone. Then connect the two pairs in the CAD software so they merge at the wing tips and at the axis via parallel transformations and without changing the pitch.Personally on first flight I noted sound difference but as others have stated hard to say if that equates to less dB (Quieter) but I would say yes. I've been recently reading some companies sell "stealth" propellers which "improve performance and are more quiet".

Thomas Sebastian, a senior member of the Lincoln Lab’s structural and thermal-fluids engineering group, explains that the design for these low-noise propellers comes from experimental airplanes in the early 1900s and those operated during World War 2. Our team has more than 40 years of experience designing and manufacturing propellers for Model Airplanes and Drones. In a minor collision, they will shatter, unlike the OEM props, making a crash more likely, and recovery less likely. For more than 40 years we have envisioned, designed, and manufactured model airplane and multi rotor propellers with utmost precision and care.So to answer the OP’s question, I feel there’s a difference, but I’m not sure I can describe them as quieter. I can only recommend that you make a wooden or aluminum mold with a CNC, then you put your 3D print on it and put everything in the oven a little below the melting temperature of the plastic. The challenge will be to find the right distance between two consecutive blades to avoid cavitation of the next blade in the flow of the previous one. The European Union Aviation Safety Agency (EASA) has even published guidelines explaining how UAS manufacturers and government agencies can measure the noise level of drones, ensuring they are not a nuisance to people and wildlife. I'm not sure I feel like going to the level of running it all through ANSYS to simulate lift, but I probably could.

They also reduce the noise level of your drone, meaning you can fly in noise-sensitive areas without worry. Not as good as a prop guard, but still a lot better than nothing and they don't add hardly any weight compared to a prop guard. Pour un drone de ce prix il est préférable de prendre le produit original car c'est l'élément essentiel du vol en sécurité. HIGHER ACCURACY - Mini 3 Pro propeller blades have been tested for precise dynamic balance with high precision and the best flight effect.With the Stealth Upgrade propellers you are getting even better noise suppression and more pleased to the ear pitch sound.

Ive bought a couple sets of master airscrew stealth props and i will continue to keep some onhand strictly for the colors. The best would be perhaps to make the part in parametric so as not to have to redraw everything with each modification.

But when the cold temperatures and strong winds in winter, it was rather noisy compared to the original DJI Propeller.
