It isn't necessary for your current setup Jason. If you buy a new motor 
either a modified or a stock motor excluding the 540 you will need to put 
capacitors on the motor supress noise emitted from the motor. Electronic 
speed controls require you to put capacitors on the motor. But don't worry 
about capacitors for now. When you buy a new motor or ESC solder capacitors 
on the motor.
