Yeah, I just got a private reaming from Steve K for not paying enough attention to the question. I could not find the angle for the spar/strut fitting in the plans, either.
And, now, I wonder how we did install the fittings. We finished the wing before the fuselage was finished. Maybe just made some measurements, allowed some dihedral, and installed.
I'll go to the airport and measure the angle. Even though Stubby is a "bastard" DE, these parts are built to the plans. May take several days to get it.
