Actually, when you get all the parts together, after painting it up, the structural parts go together very fast. Literally in one afternoon if you put the work into it and know what you are doing. The electronics take about 5 hours of work to pop it in and solder up. That is probably the hardest part, just getting the lights in right and leading the wires through to the power boards and lights and sound. It is absolutely fun to go out on Halloween Ghostbusting, had an incredible night of fun with my sons doing so.
