Kazuma mini falcon 90cc or redcat mpx 90
 

FYI:: Just so you don't make a machine mistake, please consider:::
A trip to your race place rules may help. I know of no organization that allows a 6 yr old on a 90.
MX??!! And your thinking of a chineese quad? The better quads have a difficult time with on track reliability let alone a low cost machine.....DRR my friend [img]i/expressions/face-icon-small-smile.gif[/img]
