A more important point to make...
If you don't pay attention to detail (follow the manual closely), this is not the chassis for you. Similar to the Awesomatix, this is not a beginners build kit.
This will probably be my 25th-30th kit. I still run into issues.
I'm up for the challenge. My MAIN issue is hand fitting/machining/sanding parts to fit. It's very frustrating to me. Does the 4X have this problem? Is the T4 a more appropriate car for my requirement?
