Two gyros located beneath the seat whirl clockwise at 5,000 to 12,000 rotations per minute. Like any rapidly spinning disc, such as an airborne Frisbee, the rotors naturally stay level.
Single-axis gimbal assemblies, which hold the gyros, can tilt forward and backward. When tilted forward, the gyro generates a powerful torque that pushes the C-1 to the left. When backward, the vehicle leans to the right.
The computerized stability-control module changes the tilt of the gimbals to keep the C-1 balanced. The vehicle remains level when driving straight or standing still and leans at an angle when making turns.
A 10.4 kilowatt-per-hour battery pack lasts 150 to 200 miles on a single charge.
