This thin electric propeller from APC has dimensions of 8x8". It is the result of a computer-optimised design that gives the propellers a thinner profile and more "bite" with minimal noise. The propeller features a lightweight moulded-nylon construction that reduces the rotating mass, giving you a higher output and longer life. The reinforcing fibres in the prop helps it to maintain a true and constant pitch regardless of the RPM. It is a great choice for electric-powered and park flyer-type aircraft.
