APC Props Slow Fly 9x3.8 RC Aircraft Propeller - APC09038SF

The APC Props 9x3.8 Slow Fly propeller (APC09038SF) is a fixed-pitch RC aircraft prop designed specifically for slow-fly and park-flyer style fixed-wing models. APC is one of the most trusted names in RC propellers, and the Slow Fly series is engineered to generate strong thrust at lower throttle settings, making it well suited to lightweight foam aircraft, slow-flyers, and electric park jets that cruise at reduced airspeeds. The 9-inch diameter combined with a 3.8-inch pitch delivers the broad, efficient blade angle these types of models need to stay airborne and manoeuvrable without over-loading a small brushless or brushed motor.

Key Features

• 9-inch diameter with 3.8-inch pitch — a combination optimised for high thrust at low RPM
• Slow Fly blade geometry produces more lift per revolution than a standard sport prop of the same diameter
• Moulded from APC's stiff, lightweight composite material for consistent balance and minimal vibration
• Suited to lightweight electric fixed-wing models including park flyers, slow-flyers, and micro trainers
• Style code APC09038SF for straightforward reordering and compatibility checks
