I didn't know to post it in the 1/8 scale buggies or the nitro stadium truck forum so now its in here. Which is better and why?

well 1/8 scale is bigger and more for racing. i have teh nitro rustler. its awsome. its durable, it goes fast. and it cant go through anytin you want

A 1/8 scale buggy is great for both racing and bashing. I have a Hyper 7 and love the thing. Very fast and loves to fly. I love jumping the thing.

can the rustler go through grass and dirt well even though its 2wd?

2wd can go in some grass - just not really tall grass. 4wd is better for that.

i be drivnin my rustler through tall grass and mud sand everytin you name it
