I want to get this rmx 2.0 rtr but the description contradicts its self. Does it come with a LSD-X or a LSD-S 2.0? Does it have the MB rear arms, HT rear arms or standard? I wish rcMart would either have a way to ask questions about parts from technicians or put more information in the description or have a legitimate return policy. Come on rcMart it's 2018. Update your website and company policies or become outdated.
