Guys...this happens with out the Turnigy chip installed as I've said several times. I put that in to see if it stops it. I was just wondering if this was how the gear box was either designed, or a problem with my transmitter (if theres a setting that tells the receiver to quickly forward which causes a hard brake) or what. Seems that this is a common problem with new Tamiya's out of the box or so I've been told. So I'll give it a while to see it it stops on it's own.
