    I have a few questions on Kort nozzles.

    1) Is there a rule of thumb for tip clearance?
    2) Do the prop tips have to be squared off?
    2b) If they do have to be squared off, do you modify a "normal" prop by cutting off the tips or do I find a custom square tipped prop?
    3) If the nozzle is made from composite, what sort of scantlings should I use?
    4) What is the effect if the nozzle isn't a ring, but more of a square outside shape with a hole "drilled" in the middle?

    Thanks for indulging.
