Searching for Don Bailey/ Aerodynamic Washout

Does anyone out there have an e-mail address for Don Bailey?

You can send it to tiggs@eos.net if he doesn't want it worded about.

Failing that, can anyone explain aerodynamic washout to me?
By that I mean how do you choose airfoils for root and tip to get washout, but avoid putting a 'twist' in the wing.

Any favorite airfoils for this?

Aerodynamic washout

I suppose you could create aerodynamic washout by using an airfoil with a lower lift coefficient at a given speed and angle of attack than the one at the root.

Thanks for the input guys. I know the article you are talking about...I'm away from home right now for 10 more days, and can't get the article.

Michael, I got your e-mail, thanks again.

Any practical examples/suggestions?

E205 for root and E168 for tip?

Thanks for any input...
