I think obsession is one of the best parts of scale modeling. Even if I dont reproduce every joint, I want to know how it was really made. What did it really looked like. There are different levels and i am glad; Peter McDurmott spends 10 years making one of his models. I am sure like all, he builds 5-10 regular planes during the super build time. You cant build everything to top level; you would never fly anything or have the confidence to fly them.
