ahhh I saw that in the picture and was going to ask about it. 4,700 micro farads is the correct size? I'll tell my buddy who has glitch issues.Even room for my capicitor. I have found with several Tamiya esc's that their bec is crappy, drops to low under power and makes the servo twitch bad, so head up to your local electronics store and grab one of these caps and problem solved.
