Yep...My Old Man is into that level of detail with flying model airplanes. He has a machine shop to make all his parts..just like the real thing including minature real turbojets for engines and he is over 80 years old and still gets into it.
I plan on spending at least 6 months on my Silvia model I bought. I will need to faricate some underpinnings as the model is detailed but not a rolling /working example. It gets hard core actually. I want all my lights to work as well including turn signals. Since the hood does not lift, I will cut and hinge it and over time build a replica CA18DET for it...but that will be way down the road. Yep..it gets hard core, and expensive for something to look at. Call it automotive jewlery. At least my old man Flys his! The ones I fly are not that detailed at all. Good, not intense. Just get a good cox 30 and a prop and have some fun.
It would be cool if his model actually would crank up and run..maybe it does..have not read into it yet. Some folks spend countless hundreds of thousands of dollars on models. I knew one dude that build a model boat so big he rode his kids around in it. All radio controlled. Talking about wierdness...
