Hobbywing S.BUS2 Telemetry Adapter for Futaba is a compact data transmission module designed to send ESC telemetry information from supported Hobbywing ESCs to compatible Futaba S.BUS2 radio systems. When used with a supported ESC and Futaba equipment, it allows pilots to view operating data such as voltage, current, RPM, temperature, and ESC status information in real time.
This adapter is especially useful for pilots using Hobbywing Platinum V4, V4.1, or V5 aircraft ESCs with data backhaul support, as well as selected Hobbywing car ESCs that support telemetry data output. Its small 25 × 13 × 6mm body and 3.5g weight make it easy to install in RC helicopters, airplanes, and advanced power-system setups where real-time ESC data is important.
Use this adapter only with compatible Hobbywing ESCs and Futaba equipment that supports the S.BUS2 protocol. Always check the ESC manual, Futaba transmitter firmware, receiver compatibility, wiring direction, voltage supply, and telemetry support before installation.

Real-Time ESC Telemetry for Futaba S.BUS2
The S.BUS2 Telemetry Adapter works as a data bridge between a supported Hobbywing ESC and compatible Futaba S.BUS2 radio equipment. Instead of changing the ESC’s throttle signal path, it adds a telemetry data path so the ESC can send real-time operating information to the Futaba system.
Depending on the ESC and radio system, telemetry data may include information such as voltage, current, RPM, temperature, and ESC status. Some ESC models may not provide every data type, so always check the supported ESC list and the relevant product manual before installation.
Compatibility note: This adapter does not make every Hobbywing ESC compatible with Futaba telemetry. It is for supported ESCs with data backhaul function and Futaba equipment that supports S.BUS2 telemetry.
How the S.BUS2 Adapter Connects to Your ESC and Futaba Receiver
The adapter is installed between the ESC telemetry/programming port and the Futaba receiver’s S.BUS2 channel. The supported ESC port, usually identified as “- + P”, connects to the adapter “-P” side. The adapter “-S.BUS2” side then connects to the Futaba receiver’s S.BUS2 channel.
The ESC throttle signal wire still connects to the normal throttle channel on the Futaba receiver. This means the S.BUS2 adapter is not replacing the throttle signal connection; it is only adding telemetry data transmission so the ESC can send real-time operating data to compatible Futaba equipment.
Important wiring note: The adapter input voltage is 5–9V, and the “-P” port does not provide power input. Follow the manual wiring direction carefully before powering the system.
Parameter Setup with LCD Program Box
For adapter parameter setup, connect the S.BUS2 adapter to a compatible Hobbywing LCD Program Box as shown in the manual. The adapter “-P” side connects to the LCD Program Box “ESC” side, while the “-S.BUS2” cable is connected through a Y-wire. A battery supplies power at the program box side, and the manual recommends using a 2S battery for this setup.
After connection, press “OK” on the LCD Program Box. Once the connection is successful, the current firmware version will be displayed. Use “ITEM” to browse parameter items, “VALUE” to change the selected value, and “OK” to save the setting. After setup is complete, disconnect the adapter from the battery and power it up again to confirm the parameters are current.
Setup note: This parameter setup is for the S.BUS2 Telemetry Adapter, not for changing every ESC parameter. ESC setup still depends on the supported ESC model, LCD Program Box compatibility, and the ESC manual.

Programmable Parameters for Adapter Telemetry Data
The S.BUS2 adapter parameter setup is mainly used to help Futaba equipment display telemetry data correctly. Parameters include motor pole logarithm, pinion, main gear, and start slot. These values help the radio system calculate and display data such as RPM or telemetry positioning correctly.
| Motor Pole Logarithm |
1–50, default 1. Used to set the motor pole information for telemetry calculation. |
| Pinion |
1–100, default 1. Used to set the number of teeth on the motor output shaft. |
| Main Gear |
1–255, default 1. Used to set the number of teeth on the main gear for gear ratio calculation. |
| Start Slot |
8 / 16 / 24, default 24. Used to manually set the starting data position on the Futaba remote control sensor menu. |
LED Status Guide
The two LEDs on the adapter help show whether the ESC, adapter, and receiver are communicating correctly.
| Red LED Flashes |
ESC is communicating with the adapter. |
| Green LED Flashes |
Adapter is communicating with the receiver. |
| Red LED Not On |
ESC is not connected properly or is not communicating with the adapter. |
| Green LED Not On |
Adapter is not connected to the receiver properly or is not communicating with the receiver. |
| Red and Green LEDs Not Flashing |
No communication between ESC and receiver, or the adapter contact point is not connected properly. |

FAQ: Hobbywing S.BUS2 Telemetry Adapter for Futaba
What does the Hobbywing S.BUS2 Telemetry Adapter do?
It allows supported Hobbywing ESCs to transmit telemetry data to compatible Futaba S.BUS2 radio systems, helping pilots monitor ESC operating status in real time.
Does this adapter control the throttle signal?
No. The ESC throttle signal wire still connects to the normal throttle channel on the Futaba receiver. The adapter adds S.BUS2 telemetry data transmission and does not replace the throttle connection.
Does the “-P” port provide power?
No. The “-P” port does not provide power input. The adapter working voltage is 5–9V, and wiring should follow the official manual diagram.
Does this adapter work with every Hobbywing ESC?
No. It only works with supported Hobbywing ESCs that have data backhaul or real-time data output support. Check the ESC manual or official compatibility information before use.
Does this adapter work with every Futaba transmitter?
No. The Futaba transmitter and receiver system must support S.BUS2 telemetry, and firmware compatibility should be confirmed with Futaba official information.
Can I use it with Hobbywing Platinum V5 ESCs?
It is intended for supported Platinum V4 / V4.1 / V5 ESCs with data backhaul function. Confirm the exact ESC model and telemetry support before installation.
Do I need an LCD Program Box to use this adapter?
An LCD Program Box is used for adapter parameter setup, such as motor pole, pinion, main gear, and start slot. Normal telemetry use depends on correct ESC, adapter, and Futaba S.BUS2 receiver wiring.
