Radu,
You have truly done some phenominal engineering on this build. Earlier you said if anyone had any tech build questions you would answer them so here it goes.
You mentioned that you could break down the cockpit into subassemblies for painting. Did you pin the tubular framework to interlock the assemblies without glue?
Speaking of the tubular framework. Did you use stock plastic rod or did you turn the section diameters on your lathe per the Bentley drawing requirements?
I have a ton more questions but I will stop for now.
Oh......what kind of digital camera are you using? The pics really show the detail.
