Flycatch,
Nitro beat me to it, but your incidence angles relative to stab sound incorrect. I too have the Black Horse Pitts and in stock form both wing incidences were backwards IMO, right out of the box. Notonly were the incidence angles wrong they variedbetween wing panel as much as 2.5*.....No bueno..... I have never "assembled" an ARF and not verifed a setup, as wing incidences,DT and RT willofferpoor handling characteristicsthatleave the new owner with a sour taste.If these important steps arent verified your simply assuming the manufacturer got it all right and there was/is minimal variation in their jigs when the ARF was built.....Get these nailed down for your style of flying and application or what "you" want the model to do and then dial in the CG.You can set it up a multitude of ways, CG/balance on the top wing or the bottom wing, but I wanted mine to be dependable.....period. Scale aerobatics was my goal... Im running .5*+ bottom wing, 1.5+ top wing, 6*DT and 2*RT.The CG is setup on the bottom wing via the MAC.... It a solid flier at these angles, my approach speed is nice(bipe benfit!), but I could use a tad less positive wing incidence on both, maybe 0* bottom and 1*+ for the top wing.....
