I have been for about a year now. The spinner i am currently using wasn't drilled correctly for my 3 blade prop. I had this backing plate on the shelf and though it could use it for testing purposes. I thought i was careful but it wasnt enough. At least the prop is ok.

Goodie for you!!!

If in doubt, throw it out!
