Wing Tip Shape

[MARK CLARK <CLAM@KIDD.CO.ZA>]

I have been doing a bit of research on wing tip shape, and it would appear that
a smoothly rounded tip produces the most induced drag, because of the ease with
which higher pressure air can on the bottom of the wing can *escape* around
to the top of the wing.

I am considering a Hoerner wing tip which appears to reduce the tip vortices. I
shaped one out of scrap foam over the weekend which matches nicely with the rest
of the wing.
