I admit the Air is on the noisy side but I’ve heard the “quiet kit” and it’s not all that impressive. If you're running a script or application, please register or sign in with your developer credentials here.

My experience with MAS Stealth props is not different than the OEM: more or less the same noise and performance.

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. Quieter, low-noise propellers are important because the noise impact of drones can become a barrier to their adoption, especially when operations are to be conducted near people or in urban areas.

So if they have the same pitch and length and width, then the lift will be a lot more and it will spin slower but take more power. Any one who has ever flown knows that if increase the pitch you cut back the “R”s and the noise level drops.The best would be perhaps to make the part in parametric so as not to have to redraw everything with each modification. With each set of MINI 3 Pro / 4 Pro STEALTH Upgrade Propellers you will gettotal of 4 propellers - 2 CW propellers (4 CW blades) and 2 CCW propellers (4 CCW blades) with a full set of screws. Ive bought a couple sets of master airscrew stealth props and i will continue to keep some onhand strictly for the colors. Can't comment as yet on any extra air time as I only burned through half of one battery, some claim extra 2min flight time per battery is observed with the MAS props. 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.

We don't have any information regarding this accessory however, I will take this as suggestion of yours and will forward to our designated team for attention.Otherwise, they are a nice upgrade for quieter flight, and supposedly also add a minute of flight time. Probably just serendipity, but it gives me pause, since I have only flown with them 6 times, and have hundreds of flights on the OEM props with no crashes! A team working at the MIT Lincoln Laboratory says it has come up with a closed-form propeller design that can significantly cut down the loud noise commonly associated with consumer drones.

Bought some MAS stealth props a week or so ago now, first chance I had on Sunday just gone to get outside and have a buzz around over some water.Constantly improving our technology and production processes throughout the years, we have developed perfectly efficient and incredibly silent blades, second to none. Would love for somebody to try them out with the Mini3 but I fear simply creating some and bolting them onto the Mini 3 will not work.
