    Prop Pitching Question...

    When you guys re-pitch the Dynafly props, how much do they "grow" in outer diameter when pitching them up? I'll be doing this after some initial combo testing on my GPR, and I'll be making the adjustments out of the country at my lake house. Trying to decide what I'll need to make these adjustments to the outer diameter. Right now I'm thinking files and feeler gauges and work in small, slow increments?

    I don't think I can get much of an accurate measurement with my calipers... Do you guys just use trial/error to get them dead-on?

    I've got a 4* keyway, milled head, air intake mods, Jim's ride plate, R&D 800 grate, fuel controller and some tach/EGT monitoring stuff. Is it worth taking this 14/20 to 21* right from the get-go in the comfort of my shop, or should I pitch it after getting the fuel dialed in and see where my RPMs sit? I'm heading out Sunday morning...

    Should maybe also mention that the pump shoe is also sealed up properly...
