APC Props 9x4.5 Electric RC Propeller - APC09045E

The APC Props 9x4.5 electric propeller (style code APC09045E) is a fixed-pitch prop designed for electric-powered fixed-wing RC aircraft. APC is one of the most widely used propeller brands in the RC aviation hobby, and this 9-inch diameter, 4.5-inch pitch prop is a popular choice for sport flyers and those powering mid-sized electric trainers, park flyers, and aerobatic models. The 9x4.5 sizing balances thrust and efficiency well, making it a common match for brushless outrunner motors in the 1000 to 1400 KV range paired with 3S LiPo packs, though the right pairing will depend on your specific motor and airframe.
