Rear Pusher Replacement Propeller 13x4EP - APC AP1304EP  [AP1304EP]

13x4EP Prop for Rear-Mounted Electric Motors

This APC AP1304EP propeller is an RC-scale accessory intended for electric pusher and reverse configurations where the prop sits behind the motor as a pusher. The write-up focuses on fitment considerations, installation practice, and its role in tuning thrust and handling for electric models.

Use this propeller as a direct-replacement or spare part in electric pusher arrangements. Before fitting, confirm your motor shaft adapter and prop nut are suitable for the prop’s mounting method and secure the prop with the correct hardware to prevent loosening during operation. The item is designed for forward or reverse mounting positions common to pusher installations.

For setup tuning, pay attention to static balance and runout; a well-balanced prop reduces vibration transmitted to the motor and surrounding components such as the ESC and steering linkage. Fine adjustment of pitch and prop clearance relative to the airframe or hull can influence thrust and cooling airflow for the motor.
