Your losi XXX-S sport is a fairly competative car out of the box. All you need to do is goto the losi website and use one of thier set-up sheets for the xxx-s for the application that your track is using ( i.e. parking lot track, carpet, etc... ). I really think that you got your money's worth considering that this is your first r/c electric sedan. Espeically with the electronics that it comes with ( esc, radio, and motor ). The good thing about losi is that most hobbyshops will carry parts for your xxx-s. You can also upgrade your losi to some of the more durable and light weight parts that losi has to offer. The TC3 RTR is a good car also. With shaft driven technology, its one of the best designs in the industry. I've seen both RTR's raced at my track and owner's of these cars are very satisfied considering that it was thoer first race and car also. Stick with it, practice, and most importantly, have fun. Goodluck.
