APC Props Thin Electric 15x4 RC Propeller - APC15040E

The APC Props 15040E is a thin electric propeller designed for fixed-wing electric RC aircraft requiring a 15 x 4 inch prop. APC is one of the most widely used propeller brands in the RC aircraft hobby, known for consistent balance and reliable performance across a broad range of electric setups. The 15 x 4 specification — 15 inches in diameter with a 4-inch pitch — makes this prop well suited to slower-turning, higher-torque electric motors where efficiency and thrust at lower RPM are priorities. Sold individually under part number APC15040E, this is a straightforward replacement or stock prop for builds and conversions calling for this specific size.
