Needs balancing, efficiency is fair but not like high end propellers. Made some test you can see on files tab.

These propellers were horribly out of balance, i would say even worse than the 12x4.5 SF CF props. Also because they are not SF type, they are closer to APC type, it does not generate as much lift as SF type for same rpm. They are more suitable for planes rather than multirotors. Not recommended for multirotors, get a SF type prop.

Bought these props for my Tricopter and Multistar motor 690KV with 4S. Actually, they need to be balanced and it's not a peace of cake ... some of them are very very unbalanced out of the bixler. The sound of these prop is stange with some high frequency sounds @ full throttle (like a whip)

Anyway, the profil is good (but not as good as graupner but the price is so low ... )
Good props for starting with carbon props !

average quality that needs balancing. the props look to have been hand sanded to remove the excess flashing from the mold. the hand sanding thus makes the tips not exactly identical to each other. will need to be balanced.
