I prefer carbon fiber or plastic, light weight, Body rolling. RC car is not design for you to crash
too hard chassic body cannot absort tension of cornering, if may make your car unbalance
moreover, once you crash metal chassic, if will bend into different shape
Normal fun play, plastic is OK la, even damage can change by low price, for racing or high speed playing, better use graphic. Metal is no good, it's only hard, cannort absorb vibration on crash, so the parts itself will be Ok BUT it will damage or deform other parts...
