Well, here's an area that somebody left early on. I used the dental tool to scrape away the excess fillet on the fuselage. A little was necessary on the top as well.
It worked out well and the plastic is soft enough that it did not take too long. When mating the wing tops and bottoms it is best to grind down the inside
of the trailing edges first or you will find that the trailing edges will have a gap between them that you cannot squeeze shut.
