Default "Full Flying" wings - surely it's been done?

I was looking at a plane with a "flying" elevator (also "all-flying," "full flying") - one in which the entire horizontal fin moves, rather than just the trailing edge.

I was struck with the idea of doing something similar with the wings. Instead of having ailerons, the wings themselves would rotate.

Wings are really big and heavy, but maybe just the tips of the wing - the outboard 10-20% or so - would rotate.

Has this been done? (Everything's been done...) Is it a terrible idea? Or just a bad one?

Try Google on Freewing or controlwing or fre-wing, or selzer suspension wing

It has been done, but due to the lack of more people doing it, I wonder about benefits vs complexity.
A few years back there was an article in the EAA magazine Sport Aviation, I can't find my copy and it looks like the EAA hasn't put them on the web.

Yeah.. it's been done lots of times. Usually the twisting wings would take over both aileron and elevator functions. Google 'pitcherons'

Other than looking cool and the novelty value I dont think there is any real measurable advantage.

Lots of examples of those in the slope soaring world. "Twisty Wings", both Pitcheron (twisting wing serves as ailerons and elevator) and Wingeron (twisting wing serves as ailerons, conventional elevator)

Yes. The F-18 I believe has "flying stabilizers", as does the Dave Thornburg Bird of Time.

The original Wright Flyer didn't have ailerons, the actual profile of the main wings were changed ("wing warping", it was called).

I was thinking of rotating, rather than twisting/deforming, as I have NO idea how I'd pull that off in a foamy!

Twisty wings - short list

Full flying stabilizers is a MUCH longer list.

I'll build/get a twisty slope plane some day - buddy of mine flies a Sig Samurai, WAY too much fun to pass up.
