i agree 100% with HerrSavage. Its fun to put together your own KIT, but the Losi RTRis a nice package for the money. I managed to get a racer roller kit and put what i want in it. gets expensiive fast. Losi RTR way to go, besides at some point you will have to take apart the RTRand put it all back together again so you get the experience of the build. and you can slowly upgrade with what u want. Besides right outta the box the Losi RTRis a beast and very competitive.
