APC Thin Electric 8x8 Prop
APC Thin-Electric Series props offer high efficiency and great value for your electric powered models. The center hole of the prop is designed to accept a reducing bushing to fit your propeller shaft. Included with the prop are 5 bushings to fit 3mm, 4mm, 5mm, 6mm and 8mm prop shafts.
This prop is primarily used in EF1 Electric Pylon Racing, but it also works great on FPV racing wings and other fast electric models.
According to the widely accepted Maximum RPM formula of 145,000/D for APC E-Series props, the 8x8E prop should not be used over 18,125 RPM.
