This is a replacement 4 bladed spinner/hub for a R/C Tempest electric powered with a 800mm wingspan. The Tempest is has been sold by a few different resellers
...Plus including Airfield and made by Top R/C.
For power it uses a 820Kv Out-runner Brushless Motor. The original kit comes with a set of replacement blades, but only 1 hub/spinner.

The kit is being sold again by Hobby King:

I updated the base to eliminate the need for supports. Both the old and new STLs are there.
