controller temperatures from being displayed correctly. At this time we
do not know the cause of or have a solution to the issue. We are still

Vehicle Connection Resources
- The Telemetry Link may require configuration in Castle Link. If the Telemetry Link is connected to the S.BUS2 wire or ESC, you must first disconnect them to avoid possible damage to your Castle Link USB Adapter. Then connect the brown, orange and yellow lead (labeled External Input) on the Telemetry Link to the Castle Link USB device.
- Click on the “BASIC” tab.
- The S.BUS2 Throttle Input default is Channel 3, which is typically assigned to the throttle stick on the Futaba transmitter. Please refer to Futaba’s recommendation for setups that require modification of this selection. Assignment changes made on the transmitter may need to be changed here as well. For external governor applications, select External Input in the S.BUS2 Throttle Input drop down.
- The Telemetry Link will occupy (8) SBUS2 slots. The designated start slot is 8, 16 or 24. Castle Link defaults to S.BUS2 Slot 8. The start slot can be changed if you are already using a sensor on one of these slots.
- The Telemetry Data Enable checklist allows you enable/disable specific telemetry data points. This is useful if your ESC does not support one or more of the data points, or if you are not interested in a specific data point.
- Click the “Update” button to save modified settings to your Telemetry Link.
