Chassis
The chassis achieves a lightweight and durable design by using crosshatched cardboard for the base. To deal with engine noise we placed a grounded aluminum foil sheet between the crosshatched layers and kept all power circuitry bellow this sheet. The motor is attached to two cardboard extensions from the base and attache to the wheel through a spider coupling. A simple ball bearing mounted close to the wheel was sufficient to stabilize the wheel and our custom machined axle kept the wheel in place.
