RE: Which buggy: hyper 8 or 8ight
hyper 8 is a great car. My buddy has one, very tough as been posted. I've seen it take some pretty tough hits, still going good.
Another thing to consider, while the hyper 8 is definatley not RTR. Its not a 'kit' kit either. If you want to build one ground up, put it all together, and then pick a pipe engine, etc......go with the losi. From what I've seen the losi is very nimble and almost dainty. I've been passed by a good few, but have passed many as well! I would research the couple of problems some guys have had with the losi durabilities. I think it was mostly attributed to the RTR though. Even then I don't think it was anything to get worked up over. Servo issues or shock towers or something.
