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

15x4EP Electric Reverse/Pusher Propeller

This APC AP1504EP is an RC-scale propeller sized 15x4EP intended for electric models where a reverse or pusher orientation is required. It serves as a replacement or spare prop for electric setups and is used to adjust thrust characteristics and motor load without changing the motor or gearing.

Use this prop on electric models with compatible shaft diameter and adequate motor power. Installation requires the correct prop adapter and secure fastening; always confirm the prop nut or collet matches your motor shaft or adapter. Balancing and visual inspection are recommended before each run to reduce vibration and protect the drive components.

• Installation tip: Fit the prop on the adapter, tighten to recommended torque, then check axial runout and balance.
• Tuning role: Changing to a 15x4 prop affects static thrust and motor load, so verify ESC thermal limits and motor temperature during testing.
• Safety: Keep clear of the propeller arc while the battery is connected, and replace if any cracks or chips appear.
