The amount of incidence difference (decalage) looks a lot for the Big Square, but don't let that bother you. It will be what it will be; stability and correct trim are the important factors. Don't push the CG any further forward than is needed for good stability as I've described.

Good luck!

  Yeah, thought so. Especially, as Big Square (the only drawing that I saw
  refer to a spesific CG location) claims 2" in front of the TE - that is
  75%! I just wonder how this will affect the incidence, and how much is too
  much? 3.4 degrees sounds quite good, but will it increase much if I move
  the CG forward?
