Ring magnet, latest tech in motors, how cool is that? According to the manufacturer, it's smoother than traditional magnets, great for cinematic drones. (Motor from newbeedrone)

JB showcased these on his live stream this week. Because the magnets are housed in a solid ring, it also adds structural strength to the bell itself

It was last week, not this week. Here is the part where JB briefly discusses them...

It actually look's a very good idea, any review yet?

Interesting, i was working on a motor design with a lightweight titanium/Carbon bell... This could really finish it off

oooooo, I want to see that!  Carbon would be awesome, titanium would be cool, but a carbon bell, sweet!

Oh, cool.

I was thinking that carbon would be really brittle, but if you take a hit hard enough to crack carbon then you've also probably hit hard enough to buckle aluminium, so you'd be replacing the bell either way.

You're right, even a blade strike might cause more problems for carbon.

The idea was basically to use machined carbon tube pressed onto the top part that would be milled out of titanium in one piece with the shaft inclusive.
For individual magnets there would actually be channels of titanium coming down to retain each magnet physically without the need for glue, but this type of magnet would assist this.

Ideally it'd be far more useful in an X class sized motor as the inertial reduction of a lighter bell would have a big impact on responsiveness.

Also about those who worry it would be brittle etc, remember that there are many different types of carbon and resin compounds so there would be some R&D to find the most suitable but I can guarantee that there would be a decently durable and strong carbon available.
