APC AP1504E Electric 15x4E Propeller for Model Aircraft  [AP1504E]

Compatibility guidance for APC AP1504E

The APC AP1504E propeller is a replacement part for electric-powered model aircraft where a 15x4E size is suitable. The 15x4E code denotes diameter and pitch, which you should match to your motor and airframe needs. Use the prop as a service spare, after damage replacement, or when evaluating different sizes for flight handling.

Fit considerations: the prop is intended for electric RC models that accept a 15-inch diameter and 4-inch pitch, but do not assume universal fitment. Always check the prop hub bore and the motor shaft diameter, and confirm the prop's mounting interface before installation to prevent improper fits.

Fitting advice: install the prop using the correct thrust washer and nut or a compatible prop adapter for your motor shaft, and tighten to the torque appropriate for your mounting hardware. Conduct a static spin test with the model restrained to verify clearance and that no unusual vibration occurs. If imbalance is present, use a prop balancer or small balancing weights to correct it.

Operational notes: changing to a 15x4E can affect cruise rpm and throttle response relative to other propeller sizes, with modest effects on climb and cruise. When trying a new prop, monitor motor and ESC temperatures and current draw during initial flights and only alter battery or gearing if required to maintain safe operating conditions.
