This APC AP13065EP propeller is crafted for RC electric propulsion setups where a pusher or reverse orientation is required. The 13x6.5EP designation describes the nominal diameter and pitch, and the EP marking denotes suitability for electric pusher or reverse layouts.
Installation guidance: fit the prop to the motor shaft observing rotation direction, secure the hub hardware to your motor and adapter torque recommendations, and confirm the blade faces and pitch match the intended thrust for pusher mounting.
Tuning role: switching to a 13x6.5EP alters motor load, peak RPM range and thrust output. Use a wattmeter during initial bench runs to track current draw, and static-balance the propeller before flight to minimise vibration that can impact servos, ESCs and airframe components.
Practical notes: verify hub diameter and thread or collet compatibility with your motor, check clearances for prop wash and nearby control surfaces on pusher installations, and perform short low-throttle taxi or glide checks after the first fitment.
