I thought it interesting that the other people responding to Kyler's
thread had apparently not heard of the "Rotodyne", and didn't check out
the Fairey Rotodyne (google for it!).

Wading through the misinformed responses is the price of getting the
good information that usually comes...eventually.

There IS a company working on a very cool -new- gyroplane - Groen
Brothers.

For "cool" gyros, I'd rank the CarterCopter a little higher.
