For the last two summers we have a good class of Traxxas Rallies at the parking lot races at the Hobbytown USA in St. Charles, IL. We have had from 5 to 8 cars with mix of drivers of all ages. They're a lot of fun, fast and durable. The only complaints I have heard are about the servo in the more recent models. Mine is a conversion of a 1/16 Slash and I am still running the same servo, which is 3 or 4 years old. I have heard the newer versions of the servo are not as good. The hobby shop doesn't recommend replacing a broken servo with a Traxxas. Getting the cars to handle more like a touring car is a little tricky. Of course tires are a big facto.
