Replacement Cooling Fan Blades

This two-piece set supplies black plastic motor fan blades with a 15mm inner diameter and twelve vanes each. They are designed as direct replacements for worn or damaged blades on compatible electric motors. The adjustable fit helps restore airflow without requiring a full motor swap. Builders repairing drones or RC models can use them to bring cooling performance back to specification.

Thermals Noise and Power

The lightweight 79g net weight keeps rotational mass low so the motor spins freely and draws minimal extra current. Twelve vanes move air efficiently across the 115mm outer diameter while the 18mm blade height maintains a compact profile. Plastic construction avoids the vibration and acoustic ringing sometimes heard with metal alternatives. Normal operation stays quiet and thermally stable for typical hobby loads.

Included Hardware Benefits

Two blades are supplied in the package so a spare is on hand or both sides of a dual-shaft motor can be refreshed at once. The black finish resists visible wear and blends with most motor housings. No additional mounting hardware or software is bundled, so installation relies on the existing motor shaft and set-screw arrangement. The simple drop-in design reduces downtime during field repairs.

Questions about this item

How do I fit the 15mm inner-diameter hub onto the motor shaft, and what step is often missed?

Press the hub onto the 15mm shaft until the blade face sits at the 18mm height mark; the step often missed is checking that all 12 vanes spin freely without touching the housing.

What part will need replacement first on these plastic fan blades?

The 12 plastic vanes can crack from vibration or heat cycles; replace the blade when any vane shows fractures or the 115mm outer diameter warps.

What thermal limit appears first during continuous running?

The black plastic softens above its heat-deflection point, so sustained high RPM will deform the 18mm tall blade before the motor overheats.
