    Raboesch prop Question - which direction?

    I have a question concerning selecting a proper prop. I understand that all submarine models require that the prop turns CCW when looking from the rear. I noticed in Frank Ryan's article in Subconcepts on Propellers that Raboesch seems to be the opposite desciption when ordering.

    I plan to purchase a 7 blade Raboesch prop from "Ships N Things" and want to be certain that I am ordering a prop that will turn CCW ... even if it meant ordering the "right" hand prop to get it right.

    can anyone help?? I am confused.

      It is not just the

      It is not just the Raboesch props, Engel's, are also 'backwards'. It seems the Germans view the rotation from the bow, not the stern as we do. I just received a 7 blade from Engel, and though did not know at the time, ordered RH. Since it is for my SSY Akula, it will be 'correct'?
      BTW, we should move this discussion to the R/C section.

        The "hand" of a prop

        [color=#000000]The "hand" of a prop doesn't change if you view it from the front or rear. To determine the "hand" of a prop, lay the prop on a table with one blade pointing away from the edge (12 o'clock position). One edge of the blade will touch (or seem to touch) the table top. The blade edge that touches the table determines the hand]

            Experienced model builders know how to determine proper handing. I provided the explanation for somebody who isn't an experienced boat builder.
