APC Props Slow Fly 8x3.8 RC Propeller - APC08038SF

The APC Props 8x3.8 Slow Fly propeller (APC08038SF) is a fixed-pitch RC aircraft prop designed specifically for slow-flying electric models where low-speed thrust and smooth airflow matter most. APC's Slow Fly series is a popular choice for indoor flyers, park flyers, and lightweight foam electric aircraft that run lower-KV motors and need a larger diameter prop to generate efficient lift at reduced throttle. The 8-inch diameter and 3.8-inch pitch make this prop well suited to models where a fine-pitch, high-RPM setup would sacrifice flight stability.

Key Features

• 8-inch diameter with 3.8-inch pitch — a combination tuned for efficient low-speed thrust rather than top-end speed
• Moulded from APC's standard glass-filled nylon material, which balances light weight with enough rigidity to hold pitch under load
• Slow Fly geometry produces more thrust per watt at lower motor speeds compared to standard sport props of the same diameter
• Designed for direct-mount on brushless outrunner motors commonly used in park flyer and indoor electric aircraft
• Style code APC08038SF makes it straightforward to identify the exact size when reordering
