RE: Continuation of rational of trimming
Hi BMatthews,
I understand that all measures given may cause some confusion, i shall do my best to clarify this matter.

Dag, why you want to run with such a strong stability margin?
Answ:2.1 CG @ 25% MAC
Tail Volume (TVC) =0,700
Static Margin = 25,0%
Wing Aero Incidence = 0,9deg
Lift coeff at Current V =0,12
Fuselage Deck Angle = 0,66deg
Horiz Stab Incidence =0,1deg
Short Period Pitch Damping =0,89

You wrote in your first post that "NP on CMAC = 0.4956".
Answ: This relates to NP of Cmac at 0,4956% where C is 14,25 inch and hence SM @ 25%.
Ater test flight I expect to lower some of the incidence calculated.
All this figures are a result of re-design of Zigris except for one thing, i wanted to keep main wing as is.
Best regards
