My QB center section was out of square 1/4? to the firewall. Everything still worked out with one wing zero sweep and the other having 1/2?. It made no difference and she flew straight and true. There is no way my HS is square to the end of the wing. That would be impossible on my build.
Your asking good questions, but don?t get hung up on it. QB fuselages may not necessarily be perfectly square as you are finding out.

Thanks for the encouragement. Sometimes analysis paralysis can sure slow things down ;)

I'm not sure how to equate the HS being square with a point on the firewall and the wing being square using a point on the aft fuselage, being that the firewall is off by ⅛" :confused:

Yes, you’re correct about the plans. My bad. It’s been a while since I rigged mine.

The comment I made about using the point on the firewall is due to the fact that the point furthest away from the HS should in theory yield a more accurate measurement because of the better angle.

Thanks for all the help - VAF is great!
 
I'm sure this is boring by now but thanks for everyone who helped get my head around this.

Today I finally mounted the HS. It came out perfect.
