After requests from many pilots around the world, APC now produces Black colored versions of their popular Thin-Electric Series!
The APC E-Series Pusher props are designed to turn in the opposite direction as compared to the standard E-Series props. In most cases, you can simply run the motor backwards in a pusher application, but there are some cases, such as in twin engine planes, Multi-Rotor craft or special co-axial power systems, where you need a matched pair of props with one normal rotation and one reverse rotation propeller. For these types of applications, the pusher props are perfect!
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.
According to the widely accepted Maximum RPM formula of 145,000/D for APC E-Series props, the 7x4EP prop should not be used over 20,714 RPM.
