Super light mod

[gek]

I'm new... I am so new I don't even own a bit Char G yet... (it's on it way), but i'm hooked...

I allready own a majorete mini RC and have had great fun Moding it (headights, steering).

I've been looking on the net and found a great mod:
http://www.age.jp/~ex2/bit/01_custom.html
This does look excelent... The advantage that I have is that I work for a Japanese corporation so I have plenty of colleagues to ask about translations, but one thing bothers me.

The Mod include's a capasitator (****ty spelling) linked between the Front and Back terminal (F, B). The website explains that if you connect the lights without this capasitator the engine wont have enough power to start the car.

Has anyone doen this mod and if so what are your findings about the capasitator?
