A 1/18th handles very differently to a 1/10 because -proportiantly - they are much lighter so they handle differently and any bump and stone they hit is HUGE for something so small. I would say go for a micro though if you intend to do some backyard bashing unless you mean uncut grass and pretty bumpy/muddy in which case go for a 1/10 stadium truck like a rustler or stampede. If you wanna go seriously bumpy, go for an e-maxx.
