Interesting. When I was a kid I built a LOT of model planes, tanks, & warships, from companies like Revell, Airfix, Hawk, and maybe a few others, but nothing with that level of detail - I was especially impressed with the model "wiring" on the engine.
What made me quit was the declining quality of the model kits - parts just didn't fit anymore, and it's hard to file or trim them to make them fit when they're undersized or warped. Looks like some better quality model kits are on the market today.
