Worst for me was the Tamiya Manta Ray. I hated it the moment it was built, the front dogbones only lasted for approx 5 battery loads, it was extremely slow and boring to drive with the stock motor. Maybe I only felt this way because of the Astute I had before: fun to built, fun to drive - except for the rear suspension and the fragile front plate maybe...
The best time I had so far with an RC car must have been with my Xray T1R, because at that time it took me only five minutes to get to the track - if the traffic lights were red!
It was also the only car that took me into an A-main, in which my result was, err, below average.
