RE: Brushless options
we drove it in front of a 2006 ford f-150 so the speedometer was correct, we put the F-150 in cruise control at 50 mph and the xxx-t was still pulling away very very slightly but we didnt get to test to see if it went 51 or 52 because we got pulled over by the police. when we ran it we had a hot fresh battery right off the charger in, it also may be the way the mamba max is set up.
