There have been two problem fit areas with this build.
The first is the lower fuselage seam. There is a step in both sides that is intended to accommodate the central insert that has the detail for the stitched join. These two steps are not the same depth making the joining surfaces minimal. Coupled with this is the fact that the central insert is thin and flexible, so great care needs to be taken in this area.
The second area is the join between the fuselage and the under surface of the central wing root. It is not an easy area to get to due the the complex curvature of both the wing and fuselage.
After a gloss coat and decaling the wings I sprayed a matt coat and weathered them with a brown wash underneath (Vallejo Brown 76.513) and a mix of khaki green and black wash on top (Vallejo Dark Khaki Green 76.520 and Black 76.518) to highlight the ribs.
Then I attached the middle wing to the fuselage, although I had to touch up the upper wing centre section/fuselage joins with the main green paint.
Then I tackled the under wing root gaps by brushing on white glue. This took a couple of applications.
A delicate job of painting the underwing fairing green finished it off.
Then I added the fuselage decals.
The lower wing in the following photos is only fitted in place, with the lower cabane struts attached to the lower wing.
The fit and alignment of these parts is great.
You can also see the control cables in place on the tail and upper wings. These are from an old wire guitar high E string.
The decals are fine except that the clear decal film over the serial number and data table below the port cockpit side is rather thick, giving an annoying silvering look when looking at them even slightly off vertical.
I don't thing this is silvering and a friend had the same problem in spite of taking great care with gloss coats, etc. I think that the decals are just thick, rather like the old Dragon and Tamiya decals.
