any stadium truck is pretty much a good newb truck, and the rctogt is a well proven one. Everyone has one so finding help shouldn't be a problem.
aS FOR EXTRA STUFF TO BUY:
glow plugs
glow plug igniter(get a good rechargble kind)
spur gear
airfilter oil
afterrun engine oil(a few drips throught the glow plug hole and through the carb opening)
failsafe
receiver battery (AA cells run out of juice quickly)
