APC AP1513 PROPELLER 15x13 (120 PATTERN) RC propeller spare for electric models  [AP1513]

15x13 propeller overview

This 15x13 (120 pattern) propeller is an RC-scale replacement part designed for electric hobby aircraft that accept the 15x13 mounting pattern. The blade geometry and 120 pattern designation describe hub and pitch layout rather than motor or shaft specifics, so verify your model's hub diameter and spinner clearance before fitting.

Installation is straightforward for hobby workshops: mount the propeller on the correct hub size, secure with the factory nut or adapter, and perform a static balance check. Balancing reduces vibration that affects onboard electronics such as the ESC and motor, and it helps preserve servo and bearing life in the drivetrain.

For tuning, think of this propeller as one node in the power system tradeoff between thrust and RPM. Swapping to a 15x13 changes load on the motor and current draw compared with smaller-diameter or lower-pitch props, so confirm ESC and motor temperature during test runs and adjust gearing or throttle curves as needed.

Maintenance notes: inspect the blades for nicks or delamination after hard landings, re-balance if you trim or sand blades for minor repairs, and replace if structural damage is evident to avoid undue stress on the motor and hub.
