One great thing about the TC6 is the price. The car is very competitive but much more cost efficient compared to other brands. It is also as durable in my experience.
Parts are easy available at most hobby shops!
Another point is there are some excellent aftermarket parts available. I switched over from XRAY and have no regrets (nothing against XRAY!).
I've noticed that the TC6 has a more forgiving setup window, at least in my experience.......
When you build the kit, you may have to do some fit-and-finishing, in terms of sanding down some plastic parts and such a bit. Nothing major, though!
