I'm building the Marek BF-109F in 1:50 scale. I've started a few planes in the past but never finished one. I purchased this model thinking it was reasonably simple and I would finish it. Anyway, I'm having trouble with the formers. I end up with a gap on the top. Is this normal or did I do something wrong? As it is, it won't join up with the next section. Should I make a new section and trim the fuselage piece a little along its length so that when it wraps it will fit tighter? Since this is a digital kit, I can print as many as I like, but I'm wondering what would I do if this was a printed kit? I would appreciate any help! Thank you.
