These design parameters were translated into CAD. A steel tube is used to provide most of the wheel inertia, with an aluminum support and a bearing set providing constraints. A PTFE wear ring keeps the disk from riding. A thin shim stock raceway protects wires running from avionics to the payload. All components except the bearing seat mechanically mount to a new aluminum bulkhead. The system has an optimized mass of 840g. Superior performance is almost certainly possible, given the wheel mass of 390g and the motor ass mass of 205g, which comprise the only 'essential' components of the system.
