Actually, if a dimpled wing would work, you'd see them on full-size aircraft. Just because it works on a golf ball doesn't mean the application is universally adaptable. Aero engineers have looked at almost everything to try to get more efficiency out of aircraft designs. If dimpling would work, you'd see them on the newest airliners, where efficiency is a BIG DEAL.

This discussion kind of reminds me about the "story" where an aircraft design kept having wing failures. They finally solved the problem by riddling the wing with holes. After all, when you tear off a piece of toilet paper or paper towel, it never rips at the perforations. So, by inference......
