Are you confused about POWER CAPACITORS?
A power capacitor is used to prevent the ESC from damaging itself.
Well, not really, but it prevents damage generated by the motor and battery
from hurting the ESC. When an ESC is switching on and off to give you throttle,
the electricity from the battery is being drawn vary fast. When the ESC switches off the electricity wants to flow. This is called a Ripple Current and will heat up parts
Inside the ESC. The power capacitor catches the Ripple Current and stores it,
Feeding the stored power back to the battier and motor on the off cycle of the ESC.
The side effect is a much improved mid-range throttle response, and a cooler ESC.
A cooler ESC means less voltage drop due to heat, and more voltage to the motor,
witch results in higher speeds.
This is a quote from RC DRIVER MAG. just though it was interesting Richard T
