Work is progressing slowly but it’s getting there. Before gluing the upper fuselage in place and engine nacelles together I blanked off the insides with black plastic sheet then sprayed the interiors black so that you couldn’t see through to the cabin windows;

Before spraying the upper fuselage I added a small square hole either side as the kit doesn’t have them;

The next job is to make the sensors on the fins which should be interesting plus I need to either make or find the fairing that goes on the top left of the rear fuselage of current CV-22’s. The shape of it is very reminiscent of those found on aircraft such as the Beech 18 or DC-3 so I’ll have scratch around the spares box as I scrapped an Airfix DC-3 a few years ago but kept all the useful bits.
