A two-blade version of the very popular 5051 TCS (the fastest racing propeller today according to many top pilots). Their special shape gives them a higher maximum speed and better handling in all phases of flight.
They are made of very durable material, thanks to which they survive quite a few crashes.
RaceKraft's two-blade propellers are particularly suited to high-speed engines, but they will be happy to work with the classic 2300kv ones.
