When too much is just enough, the HobbyStar 4092 is the motor you are looking for.  At a full 92mm in length this is one of the longest and most powerful motors you can shoehorn into your 1/8 truck for ridiculous power (make sure to measure to see if you have the clearance!). 4-pole design and a 12-slot stator provide unbelievable torque.
