Capacitor --

An electronic unit that acts much like a battery - it stores excess electrical energy during off time, then releases it when needed. Capacitors are commonly found on ESC's (power capacitors) and electric motors to help reduce heat and increase 'punch'. The larger the capacitor, the more energy it can store, wich results in less punch but a longer comm life. Smaller capacitors increase punch (as well as battery and motor heat). Most ESC manufacturers recommend 3 capacitors on an electric motor to help reduce radio interference (glitching) - in the olden days, you would need to solder these on yourself, but today most motors come with surface mounted capacitors already installed (send all 'thank you' letters to the motor manufacturer of your choice).
