The TQ is an excellent basher and a competant racer. Mine took ages to build but I didn't have a lot of time. I imagine you could build it well in a weekend or a day if your above average technically. Be sure you have all bits you need such as diff oils, threadlock and fuel filters. One of the best starter engines is the OS RG or the TT 21 pro. both are available as pull start or non pull start. Obviously if you get the non-pull start you will need a starter box. There are a few other issues depending on whether you go pull start or not. Steering servos are expensive for good ones and people are divided on the cheaper ones with the right specs. You won't go wrong with one of the sanwa (airtronics) top line servos.
Hope this helps and ask if you need more info.
