Servos


The brake servo pushes a brake lever that connects to disk brakes on the left and right wheels. The pusher is a slotted PVC tube designed so that the rider can use the lever as an emergency brake. Brake lever and servo are between the rider’s legs. Steering servo is linked to the tie bar connecting the front wheels. It is under the seat. Both servos are cabled directly to controllers inside the C2 box.


C1 and C3 Pilot


This is the lowest level of computer control.
