Thanks everyone, Jessica yes there was a sizable step at the wing root that required considerable amount of attention, Dragon there where a lot of challenges with this kit there were horrible sink marks on the upper wing surfaces above the wheel bays and some no so bad on the fuselage at the seem line. There were also so fit problems with the fuselage around the cockpit and front gear bay, and a major step with the small ring that fit over the intake. It also came with 2 vertical stab options, the one I chose required carving out a pocket for the bulge below the stab to fit into, there was no guide for this so I pretty much had to eyeball it.
