The main advantages an of elliptical wing is more lift and less drag for a given
size and is very hard to tip stall. The Don Juan was a very fast airplane, extremely
smooth, but would slow down to a crawl for landings. I've always wanted to build
a 2 meter version but the wing is very difficult to build and requires a good wing jig
and lots of patience. I heard Don say numerous times there were no straight lines on
his airplane...all curves.
