The learning curve for 1/12 is kinda steep, especially if the new guys have less-than-ideal equipment. We have had two guys get used 1/12 cars (which were well setup) and just drop them on the track, thinking that they could wheel it and probably had visions of beating up on the regulars, but obviously couldn't. They are both good offroad racers, but with our fast crew dicing it up for TQ I think they got the wrong impression being lapped by somebody every 15 seconds on average. It happened to me the first few times I tried this, and I only got good at it after I got the correct tires and put a sane setup on the car, but I did a lot of losing before I did any winning.
Now that I think about it, I haven't won in over a month, I got second in the A main four weeks in a row.

Its okay though, the guys I lost to were pretty good. My response to this may have been overkill: I bought a whole new car.
