If anyone's interested, Steen Aero Lab will custom-build a set ofvacuum-formed, laminated spars to your specs... they can build spar "blanks"as well if you want to do the final shaping. 25%+ stronger than theequivalent solid spar and very resistant to warpage, and no weight gain.Also less likely to have hidden defects. If you're a little uneasy aboutgoing to 3/4" spars, you might consider going with laminated spars to makesure the full strength is there.http://www.steenaero.com/Components/win ... _spars.cfm(Obligatory disclaimer...
