My nephew is 4, and he's a good kid. My brother, is kind of a dink, and the kid doesn't really have much. So I was thinking, I might get him a Stampede or Rustler. NIMH batts, add a 35T motor, and let him have fun with something he can grow with (if I can keep my idiot brother's hands off it), then I saw the Granite section here, so I thought I'd check in. Is anyone letting a child run their Granite? Going slow, are they fairly durable? Honestly, I'll probably get him a Rustler, but just thought I'd check first.
