    I am trying to find a good clear copy of a Bp Delta chart screw series Type B for a 4 Blade prop Ae/Ao=0.55 t/D-0.045 d/D=0.167.

    I have a selection of Bp and Delta values and need to find the eta o values except the copy i have is blurry and most of my lower values are off the top of the chart.

    Cheers!
