    Score a couple of these recently.

    What is the hot prop for these engines?

    Dean I’ve been runing an APC 7.625 X 3.25 (LP763325) That should get up up in the 20+ K range, depending on how good the K&B’s are.

    Dean,
    APC 7.8×4. Avoid the 8×4, it’ll shed blades. You are looking to go just short of 22k.
    There’s a guy out there who swears by a Master Airscrew 8×4. I’m skeptical, but I’ve seen it on an engine so I really think that he flies it.
