3mm Prop Adapter for 24gm motor (PICK SIZE)


3.00 mm prop adapter for Blue Wonder


These aluminum prop adapters fit a 3mm motor shaft, which is what is on our 24gm brushless motors.    The smallest size adapter is pictured.   Each adapter comes with the hub and “acorn” hub to tighten it up.

Suppliers have different variations so we offer a variety to pick from depending on your needs.   Listing shows the weight (in gm) first – then the prop shaft length and diameter.  Last is the overall length (with the parts screwed together, no prop). 

The smallest sizes are very light (2.7 to 4.5gm) – they all have a 10mm-long shaft

The medium size units are heavier (7 to 9gm), we call it “MOO” – these have a 15mm-long shaft.

The largest size weighs a porky 10.5gms, we call it “OINK” – it has a 20mm-long shaft.

To accommodate thicker prop hubs, longer prop shafts are needed. We also have a 5mm nut and washer available which can replace the “acorn” nut and provide extra room.
