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

Electric Reverse/Pusher 15x4EP Propeller

The APC AP1504EP is an RC-scale propeller in 15x4EP format for electric models that require reverse or pusher mounting. It is commonly used as a spare or replacement to tweak thrust delivery and the load placed on the motor without swapping gearing or motor units.

Use on models that match the prop shaft diameter and have sufficient motor power. Installation demands the correct prop adapter and secure fastening; always make sure the prop nut or collet is compatible with your motor shaft or adapter. Regular balancing and visual inspections reduce vibration and protect the drivetrain.

• Installation tip: Position the prop on the adapter, tighten to the recommended setting, then check runout and balance before flight.
• Tuning role: Upgrading to a 15x4 blade will change thrust output and motor loading; monitor ESC and motor temperatures during initial trials.
• Safety: Keep hands and tools away from the prop arc while the battery is connected, and replace any prop with cracks or chips.
