Foxeer Donut 5145 Props

They work.

Not very durable. They may be a little quieter. Don't seem any more efficient.

Defiantly a prop to give a go if you want a quieter sounding prop...

I don't think they preform any better vs. my Genfam or Ethix props but they do seem a bit quieter.

They are soooo brittle!

Performance is ok, they fly with a slightly lower tone. But the quality of the plastic is a deal breaker. They will break if you look at them the wrong way. They definitely need to be revamped for version 2.
