APC propellers computer - optimized design gives these props a thinner profile and more "bite" with less noise. They are made from lightweight molded nylon construction which helps reduce rotation mass for higher output and longer life, and reinforced with carbon fibres which helps maintain true constant pitch at any RPM.
All props require balancing prior to use. This is very important. Please ensure that you balance your prop before installing it onto your aircraft.
