The APC APC10010E 10x10E Thin Electric Propeller is a 10" diameter, 10" pitch thin electric prop for maximum top-end speed on electric RC aircraft. The 10" pitch (equal to the diameter) is an extremely aggressive pitch ratio delivering the highest possible top-end speed from a 10" prop — requires a high-KV motor with sufficient power and current capacity. Injection-molded composite, precision-balanced, made in the USA.Key Features Part Number: APC10010E Diameter: 10" Pitch: 10" Type: Thin Electric (E series) — maximum speed Injection-molded composite construction Precision-balanced for smooth, vibration-free operation Made in the USA CompatibilityHigh-speed electric RC aircraft using 10" diameter propellers — verify motor KV, battery voltage, and current capacity carefully before selecting this extreme-pitch prop.Benefits 10" pitch delivers maximum top-end speed from a 10" diameter prop Thin electric profile reduces drag for efficiency at high RPM Precision factory balance minimizes vibration Made in the USA — consistent APC quality Quick TakeWant maximum top-end speed from a 10" electric prop? The APC APC10010E 10x10E delivers extreme pitch performance — factory-balanced, made in the USA.
