Welcome aboard
The kit includes 3 external tanks. The laser cut formers fit very well, with no need for sanding to put them in the correct positions, at the joints. That’s a good indication for the plane itself, which has a lot of structure.
The larger tank noses are not modelled to my taste. I’d prefer a solution with either more petals or, preferably, with one or two extra sections so that the petals would be smaller and the joints less conspicuous. Another oddity is that the fins are canted upwards. According to the pictures that I have seen (after assembly, unfortunately), they should be canted downwards. I’ll probably have to reposition them…
