Ok, I'm not sure if I have a problem or not. I am building a SS7 with factory built wings. When I put them on the fuselage with the lift strut and rear spar bolt through the top of the rear spar in preparation for rigging I noticed the vertical centerline of the front spar doesn't seem to line up with the centerline of the front attachment lug. The vertical centerline seems to be about 1/8" to 3/16" further forward. Would this be normal? When I measured center to center of the attachment lugs it was 27 7/16". The spar distance is 27 9/16". Guess I'll be calling John on Monday but any insight would be appreciated.
