🚨 THIS DRONE SWAPS NORMAL PROPS FOR 3D-PRINTED DUCTED FANS. Those swirling white shrouds enclose the blades completely. Ducted designs cut tip vortices, boost low-speed thrust, and make the whole craft quieter and safer. Experimental aerodynamics you can actually fly.

talks about the design further and links to the 3D printable parts

👍🏻

Here is a link to the real content this shit reposter left off.

Mostly a hover and low-speed machine. The shrouds boost static thrust, cut tip losses, and add safety and quietness, but in forward flight the added drag usually cancels those gains and an open prop is more efficient.

Yes but you add no link/url to original youtube vidéo... Source ?

Actually, I don't know about that I am sorry for that

Are the shrouds paying off in forward flight too, or is this mostly a hover machine?

@LeahRebeccaUK

I think it can play tennis by itself. Someone who owns this please try

👍🏻

how much quieter

About 3–7 dB quieter in typical tests (roughly half the sound pressure at the high end), mainly from reduced tip vortices, though some designs show little net gain or even higher broadband noise.

@Noctua_at I have and idea...🤔

@Noctua_at ?

Thrust to weight?

No exact number published. It flies and hovers easily, so TWR is comfortably above 1:1 (typical controllable multirotors aim for ≥2:1). Ducts usually add 5–20% static thrust versus open props of the same size, but the extra weight and drag mostly help only in hover.

Nice!

Thanks

Make complete sense. Ducted and vortex’s have always been the way!!

Open source?

quadmovr

Pretty amazing... but what about in lower performance setups? Smaller motors etc.🤔

To further reduce drag, you can also try giving the surfaces of critical parts a texture like that of a golf ball.

@Grok is there a manufacturer for dji5 drones ?

🤯

File is available online?

So simple
