PATRICK, I want the wing area to be about 125 sq.", so I came up with 5 x 25. I don't think I could ever go much less than 5" for a 1/2A model, for average chord. Someday when we're all building 6 oz 1/2A models, then those 22 x 4 wings like the NASS guys [ at DELPHI] recommended will bring the 2010 model GLH down to a new level of shrimpyness. It's funny how the mind works, 15 years ago I thought the ACE GLH was the hottest thing going for a TD. Now, with lighter gear it would be even better, and a good choice for the .074 too. Some day, someone here needs to expore what the .074 is capable of in a speed application.
