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

15x13 propeller explained

The APC AP1513 15x13 propeller is produced as a replacement blade for electric model aircraft that take the 15x13 mounting pattern. The 120 pattern identifies hub and pitch layout rather than the motor shaft, so confirm hub diameter and spinner clearance on your airframe before fitting.

Fitting the prop is a simple workshop job: fit it to the correct hub, secure with the appropriate nut or adapter, then carry out a static balance. Cutting vibration at the propeller level prevents unnecessary wear to the ESC, motor bearings and control linkages.

On performance, expect a 15x13 to shift thrust and rpm behaviour; this will alter motor load and current demand relative to other sizes. Keep an eye on motor and ESC temperatures during bench runs and first flights and adjust gearing or throttle curves where required.

Inspection advice: after hard landings check for chips, cracks or delamination. If you repair or trim the blades re-balance them and retire the propeller if any structural defect is found to avoid further damage to the hub or motor.
