I have a OS 91 and cannot find a spinner to fit APC 3-D props.

I had the same problem. I used dubro plastic spinners and just dremel'd the openings 'till they fit.

W. Wookcock:

Alm spinners can be cut out with your dremmel also with no problem. Always ballance new and modified. True-turn will custom make what you need for very little if anything. Their spinners will spoil you simply because of the quality. They are well worth the sight cost over GP and others that are bad. Its not cheep if you cant or should not use it. ENJOY

tru turn has acouple of spinners made specifically for wide props. friend of mine has one on his ucando with a saito 91
