As far as I know......
Pidge's Reedy 4200's weigh about 270g (with wires), and his Rudebits brass weighs about 130g....so that area is about 400g.
There is so little difference between ESC's, motors and servos to make any significant difference so id aim for the back end of your car to have about 400g in weight around the cell area and then just stick your electrics in?
Thats what im doing...although im ever so slightly not as good as Pidge is
