APC 7x4.1 Slow Flyer Indoor 3D Propeller LP07041SF
These props are a new series designed specifically for the low speeds typical of indoor 3D and aerobatic planes.
This is a tractor (not a pusher ) airplane propeller.
APC model aircraft propellers have been designed and manufactured in the USA since 1989. APC's blade designs are the most efficient and silent injection molded propellers on the market.
Computer-optimized design gives these props a thinner profile and
more bite with less noise.
Lightweight molded nylon construction reduces rotating mass for
higher output and longer life.
