Information about wieght of stuff

I am finding it hard to locate thoser specifiations:

Weight of Traeiler, Wiegt of a battery, weight of the CRio, Wieght of the Disitbution Board, Wieght of a single digital sidecar, Wieght of the whole assembled chassis of the kit.

Thanks in advance.

The trailer is 35 pounds. I’ve built them from the “official” plans exactly to spec for our Kick-Off and scrimmage.

Can you tell us where the center of mass of the trailer is relative to the wheel axle?
