Tamiya Chassis System
What do the numbers and letters stand for in the Tamiya line of cars? I'm interested in the off road 4wd buggies for now. This will be for my sister to play around with at home in grass, concrete, dirt etc. I would like her to race with me but she lives a little too far to go get every Fri, Sat, and Sun. So, I'm just doing some research before I buy anything. thanx for any info.
