Well what words would we want whoop worshipers , wistfully wondering what wonderful wolloowing wobbly whale world of wrongness to wisper.
Works weally well.
Ducts , why , what , how.
Why is easy . So you dont hurt stuff.
What. There are 2 choices . propper ducts with close fitting blades or vanes , or prop guards.
How , how they work . Folks have said and i have noticed , throttle controll on ducted quads seems stuck and a little tricky to modulate smoothly.Aside from the coander effect , ducted fans produce thrust by acceleraiting the air through the duct , Props on the other hand are better at just grabbing the air and effectively pushing against it .
This is how i think it works.
Conclusion.
Chase quads = prop guards if anything.
Smooth steady slow = ducts.

All on thingyverse. just one tip. re size the dcts so you dont have to trim the props.And use bullnose props for ducts . but only if you can make the prop to duct airgap under 1mm . otherwise it is best to use props with a big winglet thingy on the tip like you see on the tips of jumbo jet wings.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
