I've purchased a Pitts S1S project and soon will be trial fitting the wings and checking incidence and alignment. A friend gave me his 1974 Pitts S1S manual, which states +1.5 degree incidence on both wings and +2 degree incidence on the stabilizer. This would amount to neg. .5 degree wing incidence relative to the stabilizer. We normally see +.5 to +1 degree relative to the stabilizer. Can anyonetell me what incidence we should be looking for when I assemble my Pitts this weekend?
