I estimate the total time in building to be about 25 hours. Some have commented on how fast it was built and that is true. But I built it as an OOB project for the person who wants to build the kit as it comes out of the box. There are so many areas where the kit can be enhanced; ie, extra work in the interior, addition of the PE parts that are now available, cutting control surfaces and the list goes on. All of these steps will add time to the model but will enhance the beauty of this kit. 

When I was attaching the control lines from the tail surfaces to the control horn, I realized that a long time back I should have made a modification. The kit has the control line guides molded into the fuselage. However, they are for all of the versions. Decide which version you want and then remove the other guides prior to painting. My kit has all of the guides for all versions in place. Along this same line, the G.II version has two large paddle like pieces that protect the rear gunner from rocks and the props themselves. These are parts #8G and 9G. They have what appears to be two locating pegs on them but there are no corresponding holes in the fuselage. I removed the pegs but that seems to be a mistake. They may be to raise the pieces off the fuselage surface so the control lines can go under them instead of over as I did it. This applies only to the G.II version. Later versions have a metal frame with a screen that attaches to upper portion of the fuselage.
