mljim,

I do not have the Waco YMF kit you have but the dihedral for both wings is 2°. The angle of incidence shopuld be about 0° for the bottom wing and 0° to -2° for the top, stab about +2-3°. There is a discusion on these items in the Waco YMF forum in Golden Age, Vintage & Antique RC http://www.rcuniverse.com/forum/m_40...m.htm#11373889
