APC AP1504W 15x4W Wide-Blade Propeller for 3D and Sport Planes  [AP1504W]

APC AP1504W 15x4W wide-blade propeller for RC planes

This APC AP1504W propeller is an RC-scale replacement part sized 15x4W and designed for hobby fixed-wing models used in sport and 3D flying. The wide blade profile prioritizes thrust response and low-end torque characteristics useful for short-field lift and aggressive manoeuvres typical in fun-fly setups.

Compatibility is defined by propeller dimensions: the AP1504W fits any electric RC aircraft that accepts 15x4W propellers. Do not assume motor or adapter fit without checking the prop hub bore and shaft adapter on your model prior to installation.

Installation notes: mount the propeller using the correct adapter or collet for your motor shaft, confirm the rotation direction matches the motor's thread orientation, and hand-tighten then secure as per your model hardware. Always perform a static balance check after fitting to reduce vibration and bearing wear on the motor and ESC.

Tuning role: changing to a wide 15x4W propeller alters thrust curve compared with narrower blades, affecting static thrust and required RPM for a given power system. Use incremental testing when switching props, monitor motor temperature and ESC load, and adjust pitch control inputs and throttle mapping as needed for stable 3D or sport flight.
