We don't have the luxury of CAD/CAM to locate the various holes that need drilling out and so the ideal way to construct the upper quad is turning the air vehicle on its head and using it as a jig.
There are days I don't feel like doing any of this, and just getting started is challenging. Though I find during the course of the build that what emerges looks increasingly right or altogether less so; and as this shapes up I feel increasingly confident that it will look equally good at full scale.
