SOLD BY "ONE EACH".

All of the prop adapters on this pagefit 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! The LENGTH of the adapter's prop shaft determines the maximum height (thickness) of your propeller hub. Thicker hubs need adapters with longer shafts.

Listed here byweight (in gm) - then the usable prop shaft length and diameter. Last is the overall length of the shaft (without the cone, no prop). Made of Aluminum.

The smaller sizes are very light (2.7 to 3.5gm) - the shorter shafts are suitable only for propellers with THIN hubs. You need longer shafts for thicker propeller hubs or when using spinners.

The medium sizesare twice as heavy (7 to 9gm), we call it "MOO" - these have either a 5mm or6mm prop shaft.

The larger PORKY adapters weigh up to 13gms, we call it "OINK" - these have either a 5mm or6mm prop shaft.

The longer prop shafts are needed to accommodate thicker propeller hubs or added spinner backplates. 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.
