APC PropSlowFly: 9x4.7

 Propellers for Electric Flight SlowFly

APC Prop, SlowFly For general use on Slow & Parkflyer airplanes

APC composite propellers are designed using a proprietary PC based CAD-CAM system. The propellers have a longer and greater fiber content (60%), as compared to conventional glass filled nylon propellers. This provides substantially higher strength and stiffness compared to more conventional processes which use short or chopped fibers. The higher strength allows the use of relatively thinner cross-sections; beneficial to weight and aerodynamic efficiency.
