Wingtip Vortex: Heavy, Clean, Slow - Why?

The tapered, swept or elliptical wings tend to start stalling at
about midspan at the TE, according to the texts I have here. Not ideal,
but the planforms have advantages that outweigh stall behavior, I
suppose. I wouldn't want ever to fly a wing that stalled tips first. I
wonder if it's even legal to build an airplane that does that.

Of course, it *is* legal to build a plane that stalls tips first -- it
would always be licensed EXPERIMENTAL, and would never pass standard
certification tests.

OTOH, it would be stupid to build one that way, as the plane would be a
bear at low speeds.
