Yup. I believe the Rollers and RTRs are built here, but like was said, the parts are manufactured overseas. The statement in Wikipedia is correct but should probably be re-worded as the 8ight was the first 1/8 buggy designed by a US-based company.
I do believe their older models were designed and manufactured over here because I vaguely remember seeing "Made in the USA" printed on the box for my JRXT. But then again, marketing tends to skew the true meaning of "made in USA"...
