RE: Whiplash and os vrdf46
You have to use a TruTurn prop nut or machine the fan nut adapter just a bit to work. I turned the OD of the fan nut down to .400" (I think, it's been a while) and made the shoulder long enough to go thru a APC D1 hub. If anybody really wants them, I can get it out and measure it. That's why I ran an 1.5" TruTurn spinner on that engine.
