Shawn,There is an interesting report by the NACA done 80 years ago about thestrength of built-up sparshttp://naca.larc.nasa.gov/reports/1920/naca-report-35. By the way,that server has all the reports published by the NACA and a goodsearch engine. Since this organization existed and did research aboutthe same time the Air Camper was designed, several of the reports arehelpful if not just interesting.I'm sure most of you know this already but the NACA is the predicessorto NASA before, of course, there was a space program.Robert HainesMurphysboro, Illinois>> I remember a while back a discussion about using 1/2" spars for thewing> instead of using 1" spars and routing them, and I'm having troublefind the> answer in the archives. my question is can you use the 1/2" spardirect or> do you need to put 1/2"X3/4" capstrip on the top and bottom ends tomake it> an I-beam??
