hm...
i dont think a sprint and TC3 can be compared. it should've been more like....the TC3 vs. the Pro 3. i think, since there is a RTR TC3, if HPI had plans to rival it, they should've made a RTR Pro 3. but since we kno, and HPI knows as wel, that they've made mistakes with the Pro3, it's already too late for that idea. but with the Pro 4, it could be a different story. but i think Associated has already planted a huge anchor to maintain their position as one of, if not The, top basic to pro level racer car with their TC3. i think HPI wasn't really trying to rival the TC3 at all. i think they were just trying to reach out to the mainstream ppl who aren't so hardcore about RC-ing. anyway, YEH.
