If that's the case as soon as it picks up a few nicks and scratches it'd saw an arm almost as fast as an alloy prop.
On the plus side - the fat leading edge would definitely cost some efficiency but going by the speed impact of the propguard on my Zapcat, this new prop would probably be way more efficient than a guarded prop.
Of course that's without the slots in the blades which make no sense. You don't see aircraft wings with slots out of their main lift surfaces.

If you use your head I cant really think of a reason why you would need a prop guard....

Shame we live in the real world and not the ideal world... (everyone using their heads!!)
