The fuselage drawings for the short wings show 36" between centers on the front and rear wing attach fittings. The rear spar fitting center is 1 1/2" lower than the front fitting.

Steve, you are very rarely wrong, and I'll bet that was a simple typo...but the Drawings show the distance between the forward and aft wing hinge fitting centerlines to be THIRTY-ONE inches. The referenced "drop" from front ftg to rear ftg is correct as you have called it, and please allow me to stress HOW IMPORTANT these locations ARE! This is where the Angle of Incidence of the wings is set up (stock or modified AOI is naturally at the Builder's option, but this is where it happens, so be precise when you weld them on).

36" was between the two wings and like you said 31" between the spars. That's why pictures are worth a thousand words. :lol: Sorry, I wasn't very clear there. ;)
