1650g with a 1450mah LiFe and modern servos, that is with no effort to be light, although I don't run the carbon wheel things, which add in some weight.

Last I checked, my car was bang on the current AARCMCC regulating using two larger Mugen weights on the chassis weight holes, if I used a light weight shell or put any lighter parts on mine, I'd have to add more weight somewhere.
