This Drop-in Replacement Rolling Chassis is the perfect solution to your weekend races. After all, everyone could use a little backup. This Mega G+ chassis doesn't just go faster or handle better than the competition. It doesn't just have the ultra-low, narrow dimensions of the original Mega G to continue the reign of the most realistic HO cars on earth. It's smoother, more consistent, and more intuitive than any car AFX has ever built.
