RE: good mt?
Read the 'ultimate monster truck guide' at the top of this forum.
For $350, you will be able to choose-
CEN Fun Factor 2 RTR
Traxxas SportMaxx RTR
Traxxas Nitro Stampede RTR
Smartech Truck RTR
HPI Savage SS (w/o radio & servos)
Keep in mind you will need fuel, tools, and other supplies to support a Nitro RC. Make sure your budget
supports those items as well. Do some research on those trucks, and see what others post.
