Folding prop for Flpsky 6384

Has anyone had much luck with the aluminium folding 2 blade prop that is available though flpsky?

Any tips fir improvements to design to make work better as a foil assist.

I use the FD 3 blade seems much superior in performance as a assist.

Thinking maybe be able to modify blades so doesn’t cavitate as much.

Performance is fine as a efoil but struggling with it in assist position.
