In that case, according to his AxialRacing setup sheet he's running the option carbon chassis. But if you think he's running the OE aluminum chassis, maybe the sheet isn't up to date.
Thats the guy. Maybe it was carbon, i didn't notice.
You wont find a build thread or specs for Burbo. But it is just a stock chassis with bigbores and all the VP crap on the axles. Its nothing special.
