If this is your first RC car i recommend rtr. You will get motor and electronics included for a good price. You will only need AA batts, gas, and glow ignitor. If not first RC go kit and use electronics you already have. If you just want the best truck then get the GT2 team kit. Things to remember if you go that way. You will need a radio (should come with servos and rx), AA batts for radio and rx pack (or 5 cell rechardable for rx, and then you will need a charger too), engine, box start (if engine is not pull start), fuel, fuel fill bottle, glow ignitor. I would also get 2 or 3 extra glow plugs youll need another after break in. Lastly a lot of patients for getting your engine to run smoothly.
