HR, building is a proses of figuring out what works, even if you have done specific task sometimes it gets redone as other components come into the fray. I cant count how many times I had to redo something. Building a kit in its basic form (as per the design and manual) is much easier then a full on custom scale build. I don't know your skills (yet) but I can emagine a build like this will take well over a year, unless you come from the school of Sam Parfitt
Good luck with your build.
