I always have a 1 Ohm 25W resistor i hand together with my mini-z stuff. Together with a multimeter, they are the best tool to investigate and performance test the FETS, battery connectors, wiring, etc.
Put the resistor in place of the motor, and just floor it. Then you can measure the voltage drop between any two places easily. Between battery and its contact, from end to end of a wire, from fet drain to source, and so on. Then you will start to understand where you are losing all the power, and how to build a proper Stock class car.
