Hello gents,
The fitting of central segments is just perfect - no problem with that
Unfortunately, the last segment is a bit tricky because you need to align the engine exhaust tubes and a middle 'plate' part.
That middle part needs to go together with another one (2nd pic) and the proper alignment is just crucial to make the whole segment glue-able and looking right.
The instruction isn't clear on that so I had to check how it look on a real airplane.
Also the last segment (0.5-1.0 mm) should be a bit taller to fit with the previous one. I had to cut it to fit with the other segment and then put a small triangular patch.
Please see the photos...
kind regards
