I have a new ervo mamba edition i was useing it today for the third time and when i went to go take a run on a main raoad its power died, when i retrieved it is seemed like the gearing stripped, i checked it and it seamed fine I tightened up the slipper clutch and when i went to plug the batteries back together it started sparking like crazy and frying the plugs. ??? I called traxxas and they said to call Mamba but there closed till monday!! Please help!!
