All,

Thanks for all of the quick replies. I very much appreciate you guys taking your time to help me. I have settled on a configuration that I think will be just fine. First off I am running a 14x6 K series Master Airscrew. Next I have a Higley brass prop lock up against it and then a hex nut as a binding nut. After this combo I finally have a GP Brass Heavy prop nut. I needed the front weight for a proper balance. I have started it several times with no loosening. It tachs at a peak rpm of about 10,200. I have the top end adjusted to peak at about 9800 or so. I have not flown it yet. Hoping to do so soon.

Thanks again for all of your input.
