B44 "perfect" weight/Slipper q

[Jnunu1]

Hi

I have just completed my B44 and was wondering what the "best" weight for the car was? Out of the box with lipos its coming in at 1590g.

I have seen posts relating to adding weight to the rear of the car via lead/coins/lipos trays etc but cant seem to see what a good end weight is and why?

On another point - the mysteries of the slipper clutch! If I accelerate slowly i can hear the slipper for a few feet but when i hit the throttle full on from a standing start there seems to be no slip at all? Is this ok or am i going to kill my car?

Cheers
