They are in the works and will be available in a large diameter Constant Speed soon. We are working with Catto to optimize the propeller for Bearhawk cruise speeds and low end thrust. In the next few months we will have a full line of Catto propellers specifically for the Bearhawk line.

A Google search comes up dry for "non-planar propellor tip", including the Catto website. Aside from this thread and that video. Do these have a correct name?

I know that some pushers and certain turbine aircraft sometimes use curved tips or Q-tips on the prop (Lake Aircraft for instance, commonly do). It is old tech, that never caught on for the mass market for a range of reasons. It should be technically possibly to use this sort of prop for most aircraft, but it is very uncommon.

Wow do they make a strange / loud noise in the pusher config. Certainly not something you'd want widespread in 2024, nowadays noise restrictions more of an issue than ever.
