Smooth like butter
I haven't put them to use yet but they look amazing.
Lumenier Butter Cutter 5x4x3 Polycarbonate Propeller CW
Rip it like Wild Willy with this propeller. Lumenier got a bunch of science people on their team to make a propeller with high thrust capacity that would still be efficient. After many tries and lots of sciency calculations, they arrived at this design.
The propellers are made out of durable polycarbonate material, which ensures that hitting ghost branches, gates and other minor collisions won't affect your flight!
