APC Props 12x4.7 Slow Fly RC Propeller - APC12047SF

The APC Props 12x4.7SF slow fly propeller (APC12047SF) is a 12-inch RC aircraft prop designed specifically for slow-flying fixed-wing models such as electric park flyers and scale aircraft that run at lower airspeeds. APC's Slow Fly series uses a high-pitch-angle, large-diameter blade geometry that generates strong thrust at low RPM, making it well suited to lightweight electric airframes where efficiency and smooth lift matter more than high-speed performance. If you're running a slow flyer, foam park flyer, or lightly powered scale model and need a reliable, accurately balanced propeller, the APC 12x4.7SF is a proven choice used widely across the hobby.
