This is probably one of the most impressive builds I have ever seen, Technic or otherwise. As someone who is getting back into MOCs (system) after years away, this is also super humbling. There is probably more engineering, planning, and designing in one fender of this than in the entire model I'm currently working on. I'm over here scratching my head over relatively simple engineering problems and people are out there creating things like this. It's a wonderful model, excellent work.
