If you've got some money to burn, ie. dual Mamba or Tekin brushless systems, then go with the Mini LST. It looks pretty trick, it's just slow in stock form. The RC18x, fill in your model type, has a few short comings, but it is a really good mini. The Vendetta, Duratrax's version, gets really good reviews in RC Driver. It comes with aluminum parts that are commonly broken. The only thing I would change is the servo. The stock servo is a standard size. If you want to add a brushless, then the servo needs to be replaced with a smaller servo to make room for the ESC and motor.
