Thanks Lee, I came up with the same solutions,#1, hubcap type disc,#2, tap my son on the back of the head when he gets too aggresive throwing this truck around, While I understand that a HEAVY truck requires a bit more finess as to driving style, my son is whipping this thing around like a nitro truggy,... #2 is easily taken care,#1, seems like a good 12pak project....lol.... I'll post what i come up with.....Robert
