    Alex, Are you using the solas or skat 15/19r?
    I was turning with my stage III 8500 with the 81 with -2.5mm off the skat 15/19r prop. I heard if you take too much you might go slower..
    Let me know

    I was thinking to take off -3mm in the trailing edge of mine to see if i can get those same peak rpms in my moded RXT with the smaller 81mm ring to see if i can match the same speed numbers of my solas 4 blade prop, currently i am only doing 8350 rpms @ WOT with the stock 83mm ring but after reading this info here that i might go slower if i do this i really don't know what to do with her

    One thing,
    I was turning 8500 with 81mm and -2.5 in lake water. When I tried it in salt it dropped to 8150. So I had to go to the 82.5 mm ring nd the 83 ring to bring rpm back up.
    Finally my tunning is over. With my Rude and I have 2 props > One that turns 8500 with the 81mm ring in lake water at 81.5mph and half a tank.
    And the other 8500 with the 82.5mm ring in salt water hitting 80.4 going for 81mph with less gas.

    When you change pitch say 3mm, where is that measured from? The trailing edge or where you make that little black mark?
