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

All of the aluminum prop adapters on this page fit a 3mm motor shaft.

Our 24gm brushless motors have a 3mm shaft. The prop adapters come in several sizes (the smallest size one is pictured.) Each adapter comes with the hub and "acorn" to tighten it up. The bigger sizes have bigger acorns!

Please note that the listings show 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 small sizes are very light (2.7 to 3.5gm) - the shorter shafts are suitable only for propellers with THIN hubs. The longer 14mm shaft works well with GWS propellers.

The medium sizes are twice as heavy (7 to 9gm), we call it "MOO" - these have a 15mm-long 5mm or 6mm prop shaft.

The larger PORKY adapters weigh up to 13gms, we call it "OINK" - these have a 20mm-long 5mm or 6mm prop shaft.

The longer prop shafts are needed to accommodate thicker propeller hubs. We also have a 5mm nut and washer available which can replace the "acorn" nut and provide extra room under the spinner cone if needed.

Note that most of these adapters have a 5mm propeller shaft (for the hole in your prop) but some have a 6mm shaft. If your prop's hole is too small for the adapter, you can carefully enlarge it with a reamer or a drill bit at LOW speed.
