Cool videos there. Considering the laws of physics I knew it could be done. The trick is not to stop for any reason. Stability is the key. As long as you have a stable platform and you can keep it going straight you are golden. Trust me you do not want any kind of string to deal with at those speeds. If anything at all gets crossed up you are going to have a real mess on your hands. Think of it. If the string touches one of the spinning tires it will act like a high speed winch and wrap everything up right in the middle of your run. You just have to go for it, and for safety sakes place some kind of floatation in your design, and have a means for retrieving the vehicle should anything at all go wrong. Good luck with that.
