I'm not sure if you can install one on that particular ESC. Caps increase low-end punch and save the battery from deep voltage drops when you nail the gas from low speeds. They also make the ESC feel a bit smoother.

I cant see why not, but since I dont think it has resolderable (is that a word?) wires, you will have to splice the esc's wires to install it. Do a search for the thread on capacitors.

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

That raises the question....could you put a butt load of large caps on an ESC and get even more voltage to the motor and yadayada...or does it end after one is installed. I always run a very large one on my Mtroniks. The car always feels fast and the esc stays cool. But what if I put two (count them ladies....two!) large caps on the esc....what would happen then?

Negative cap to - battery......posative cap to + motor lead. I'm not exactly how it hoods up with 4 wires. I run 3 wire esc's. For me posative cap goes to + motor/battery. You'd have to look into that. Take some of the wire insulation off the wire and solder the cap leads directly into the filleyed wire.
