I've spent some time over the last few days smoothing out the fuselage joints. Most didn't need a lot of attention with the exception of two, the nose ring and the exhaust piece where there were steps. I managed to just about work out the exhaust (pic 1) with a lot of work with a needle file, but the nose ring will need filler (pic 2). I knew this one was coming having read a review, but the article said it might have been due to misaligning when glueing up the fuselage. I took a lot of time and care doing this and still ended up with a step. Looks like its time to open up a new bottle of zap a gap.
