Metal ACORN PROP NUT - for 5mm prop shaft

This accessory fits prop adapters that have a 5mm prop shaft.  Can be used with most small motors that use a prop adapter.  The hub gives a nice scale look and replaces the cone on the prop adapter.

NOTE:  there are TWO types, you can choose from Steel or Aluminum. The steel hub is heavier!  This sale is just for the acorn hub, the prop adapter is NOT included.  Steel Hub = 1.8gms   Aluminum hub = 0.8gms

Please refer to the pictures below.  The maximum length of the hub's internal threads is 6mm - this is the maximum the that can protrude from the propeller hub.  The steel hub weighs 1.85gm and is about 1/4" in diameter and 3/8" tall.   Best for 5"-6" props.

But that's not all!!

We also sell a smaller aluminum prop adapter that has an acorn nut, it is designed for a 3mm prop shaft.
