The kit of parts only comes with four Spikes.
If you have six motors, you need six Spikes/Victors to drive them (choose Spike vs. Victor depending on the motor, and what you want to do with them). Check section 8 of the rules for a full description of what you can and can't do.
Victors are speed controllers that take a PWM (Pulse Width Modulation) signal from the RC and a 12 V input from a circuit breaker, and use it to generate what is essentially a variable-voltage output for a motor. This lets you adjust motor speed (almost) anywhere between -12 V, 0 V and +12 V (full forward, idle and full reverse, respectively), represented in the RC code with 0, 127 and 254, respectively.
Spikes are electronic relays (they switch both +ve and -ve terminals). They can only give full forward, idle and full reverse voltages to the motor attached.
