Castle Creations Telemetry Link for Spektrum X-Bus 010-0148-00

Maybe you want to know the voltage of your onboard battery (s), the RPM the motor is turning or the temperature of your ESC. In this day and age R/C is not just one way communication anymore. Traditional radio systems just transmit signals to the receiver,, but Telemetry-capable systems send real-time data from your model back to your transmitter. The S.BUS2 Telemetry Link was developed based on communication protocol disclosed from Futaba for use with specific Futaba S.BUS2 radios and compatible Castle Creations ESCs. Telemetry data can be displayed on the transmitter screen, or for parameters where you only want to be notified when a defined threshold is exceeded, (battery voltage, ESC temperature, etc.) you can configure a vibration or sound alert from the radio.

What is Telemetry 

By definition, Telemetry is an automated communications process by which measurements (such as speed, temperature, or battery power) are made and other data collected at remote or inaccessible points and transmitted to receiving equipment for monitoring. A telemeter is a device used to remotely measure any quantity. It consists of a sensor, a transmission path, and a display, recording, or control device. Telemeters are the physical devices used in telemetry.

Why should I put Telemetry into my models ?

Telemetry has the potential, not only to improve the safety of our models by monitoring battery voltages, ESC temperature, and other critical parameters, but it also creates other opportunities to get even more fun out of flying because you’ve essentially reduced the risks of “unknown” inevitable crashes. Think of the benefits to be had from alarms that will sound to warn you when there's interference about or if your receiver battery is running unexpectedly low.

First and foremost, we need to review essential compatibility parameters.

Compatible Castle ESC

The ESC must have the ability to accept a bi-directional communication protocol that gives it the ability to transmit real-time telemetry feedback. This feature is called Link Live™ and needs to be enabled on compatible ESCs using Castle Link™. Click here to view the

Compatible Futaba S.BUS2 Radio

S.BUS2™ extends Futaba S.BUS™ and supports bidirectional communication. Compatible radios will support S.BUS2 protocol. It is also necessary to utilize a compatible Futaba® Telemetry Receiver. Click here to view the

Below is an example of an X-BUS Telemetry Link set-up for Surface, Air and Internal Governor Systems. You can see how the Telemetry Link (about 5.4 inches long) connection is made between the Castle ESC and the Spektrum® X-Bus™ receiver and Telemetry Module/System.

And how about this….there is no requirement for additional Telemetry Sensors for your Spektrum® radio when using the X-BUS Telemetry Link. There are 7 specific data points available* and you can enable/disable to your liking through Castle Link™.

Operation of a model aircraft requires your undivided attention. We encourage you to refer to your transmitter manual to configure tactile and/or aural alerts to ensure your safety, and the safety of those around you.
