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.
The APC F2B-Series Pusher props are designed to turn in the opposite direction as compared to the standard E-Series props, and are fine tuned to meet the specific needs of Control Line flyers. By running a reverse-pitch pusher prop on your control line plane, the prop torque rolls the plane to the right, and this helps keep your lines tight during maneuvers. For these types of applications, the pusher props are perfect!
According to the widely accepted Maximum RPM formula of 145,000/D for APC E-Series props, the 10x5.8-E F2B pusher prop should not be used over 14,500 RPM.
