The SC 1.08 is the same engine as the Magnum 1.08 in the states or the ASP 1.08 in Europe. My, and my buddy's, Mag 1.08s like to be lugged down instead of revving up. Our best props have turned out to be a 16-6 or 15-8. For a 3-blade, I would keep the pitch and go down 1 inch in diameter, so the 14-8 sounds good to me.
