APC AP1504EP Electric 15x4EP Reverse/Pusher Propeller  [AP1504EP]

15x4EP Propeller for Thrust Tuning

The APC AP1504EP is a 15x4EP propeller made for electric RC craft where reverse or pusher mounting is required. It is typically used as a replacement part that lets pilots refine thrust characteristics and motor loading without replacing the motor or adjusting gearing.

Fit this prop to electric models with matching shaft diameter and adequate motor capability. Installation will require the correct prop adapter and secure fastening; always ensure the prop nut or collet is compatible with your motor shaft or adapter. Balance the prop and inspect it visually before operation to reduce vibration and prolong component life.

• Installation tip: Mount the prop on the adapter, torque to spec, then verify axial runout and that the assembly is balanced.
• Tuning role: Moving to a 15x4 blade changes static thrust and the load on the motor, so check ESC thermal headroom and motor temperatures while testing.
• Safety: Do not approach the prop arc when the battery is connected, and replace any prop showing damage or deformation.
