The kit is a challenge to get aligned because there are so many
intersections. I glued the wings to the central pod first, judging
by eye to get 2 degrees dihedral in the outer wing panels with the
pod vertical. Then I attached the booms to the tailplane, making
sure the fins were 90 degrees to the stab. Next I attached that
assembly to the wings. One side needed some grinding on the
bottom of the wing, the other fit pretty well. A misfit of the booms
to the wing is I think the easiest to correct, as you end up with 90
degree intersections that are easy to fill.
I used a little Tamiya filler and Perfect Plastic Putty and didn't need to
do any sanding. If I build another I will build a jig to attach the
pod to the boom as doing it by eye resulted in a
very small error but that was enough to make the right wing tip about 3/32
higher than the left.
