Thanks Howard,, as always your unique insight adds a certain level of respect to our meager conversations regarding design,, which reminds me,, I need to pay my royalties to Messerschmidt for the use of the 109 design,, sigh,,
Tim for future reference, lucky boxes are not required for small amounts of dihedral,, up to say an inch at the tips, My 109 doesn't use them and the controls have a VERY slight spring to them, but its only noticable if you look for it. building a dihedral wing is actually only one step more involved than without dihedral,
