Buyers beware!! THis kid(traxxas emaxx) posted a Castle Mamba Monster ESC and Motor Combo as new. He waited many days before shipping and after my many attempts to contact, he sent me a beat up motor and an ESC FULL of dirt/grime. The battery connector was very obviously/heavily used. I have filed a Paypal fraud dispute w/ his Mom/sister(who I paid); for whatever reason he can't even manage his own Paypal acount. Do a search and see the other conplaints on this kid( traxxas emaxx ) as a dishonest seller.
