Strange it cogs that bad on 17.5. I've got a hobbywing sensorless speedo + 17.5 motor in another car and if you hit full throttle from a standstill it cogs for a split second then goes would've thought the Mamba would do better than Hobbywing. Have to try it with the Mamba.

Tom they don't mark ABC on the Mamba it's just marked red white black, so you've just gotta take a guess when hooking the motor up
