Aussie, the prop and spinner are both from Troy Built Models (TBM) as well. I get most everything from them.

The prop is a 22x8 PT Model and the spinner is a Pete's CF 3.5 inch

If you order from TBM, you can pay the extra to have the spinner cut out and drilled as well as the prop. CF spinners are not drilled or cutout for the prop and they do a wonderful job for jsut a few dollars more and everything will line up perfectly for the DA50
