I have said before, I find scratch building much quicker and easier than kits. My problem with kits is, as soon as I have one, I find an example of the prototype to build, then a set of plans, then compare the kit to it. Inevitably (because of the examples I choose) I end up cutting bits off, making good, adding bits and so on. It takes time and a lot of thinking
Scratchbuilding, I only have to make it once
