Soviet,
Just as easy as designing a noodle tub....
This car is a definite improvement over the Team TC4. While definitely AE went the right route with their chassis design, Jason at BMI did it sooner with his TC4 kit. That's all I have to say about that. It's not a copy of the BMI; there are only so many ways to make a effective, tunable, and stiff plate chassis for this car...
