APC AP1513 15x13 (120 Pattern) RC Propeller Spare for Electric Models  [AP1513]

APC 15x13 propeller details

This APC AP1513 15x13 (120 pattern) propeller is a replacement part for electric hobby aircraft that accept the 15x13 hub pattern. The "120 pattern" denotes the hub and pitch layout rather than motor shaft or spinner size, so confirm your model's hub diameter and spinner clearance before installing.

Installation is straightforward for a home workshop: mount the propeller to the correct hub, secure it with the factory nut or the appropriate adapter, then perform a static balance check. Proper balancing reduces vibration that can affect the ESC and motor and helps extend servo and bearing life in the drivetrain.

When tuning, treat this prop as one element in the thrust versus RPM tradeoff. A 15x13 blade will change the motor load and current draw compared with smaller-diameter or lower-pitch props, so monitor motor and ESC temperatures during initial runs and adjust gearing or throttle curves as required.

Maintenance tip: inspect the blades after hard landings for nicks or delamination, rebalance if you trim or sand the blades for minor repairs, and replace the propeller if you find structural damage to avoid undue stress on the hub and motor.
