But the main points here are the same..
Caps needed...yes
Savox power hungry...Hell yes.

As you push power through a FET, it heats up, as we are driving the gates open and shut at a high rate, the heat builds up resistance which builds up heat. A battery, whether NiCd, NiMH or LiPO can't give that instantaneous burst to fire the gate side of the FET open or shut fast enough, a capacitor can, and the higher the quality, the better it works, hence why the capacitor is there, it makes the esc more powerful but what it does is make the FET work more efficiently.
