RE: kyosho inferno st us sports 2 or caster k8t rtr
I have heard the chasis can bend on the kyosho us sport truggy, but this was about 2 years ago. I do own own one but have never run it, it is still new and in the box. The newer model does have a different cooling head. This truggy is also based upon a lot of good history and experience.
I have heard the Go truggy is a very fast and upcoming truggy, the 2.4 radio would be my choice.
If your going to end up racing Just do it right the first time, and by a AE 8 truggy or a Losi 8t or a Jamin x2 truggy.
Good luck
