FrSky Twin TW R12 Receiver – Dual 2.4GHz Telemetry (12CH)

FrSky Twin TW R12 Receiver – Dual 2.4GHz Telemetry System (12CH)

The FrSky Twin TW R12 is a high-performance 12-channel receiver built on FrSky’s advanced dual 2.4GHz TW protocol. Designed for maximum signal reliability and flexibility, it features active-active RF redundancy, configurable ports, triple antennas, and dual XT30 power inputs for demanding RC aircraft setups.

Key Features

• Simultaneous dual 2.4GHz TW protocol (active-active redundancy)
• 12 fully configurable channel ports
• Each port supports PWM, SBUS, FBUS, or S.Port
• Triple 2.4GHz antennas for improved signal reliability
• Dual XT30 power input connectors for redundant power systems
• Built-in power switch function (supports external switches)
• FBUS protocol support for single-wire control + telemetry
• SBUS Out (16CH / 24CH) and SBUS In (signal redundancy)
• Over-the-Air (OTA) firmware updates
• Basic black-box data logging

Dual 2.4GHz Active-Active Redundancy

The TW protocol uses two active 2.4GHz frequency bands simultaneously, unlike traditional systems that rely on a backup signal. This active-active design improves signal stability, reduces interference risk, and provides more reliable control during flight.

Configurable Channel Ports (Major Advantage)

All 12 ports on the TW R12 are configurable, allowing each port to be assigned as:

• CP1: PWM / SBUS OUT / FBUS / S.Port / SBUS IN
• CP2–12: PWM / SBUS OUT / FBUS / S.Port

Using FBUS protocol, both control signals and telemetry data can run through a single wire. This reduces wiring complexity and simplifies installation when using compatible devices such as FrSky XACT servos or advanced sensors.

High-Reliability Power System

The TW R12 features dual XT30 power inputs, allowing redundant battery setups for increased safety. This is especially important for large or high-value aircraft where power reliability is critical.

The built-in power switch function supports external switch panels (optional), giving you flexible and secure power control options.

What’s Included

• FrSky Twin TW R12 Receiver (×1)

What You’ll Need

• FrSky Twin-compatible transmitter or RF module (TW protocol)
• Power system (2S recommended)
• Servos and aircraft setup

Best Use Applications

• Large gas or electric RC airplanes

Why This Receiver Stands Out

The TW R12 combines true active-active RF redundancy with configurable ports and dual power inputs, making it one of the most flexible and reliable receivers available. It simplifies wiring while increasing system reliability—especially for advanced or large-scale aircraft.

Modeler’s Tip

Use FBUS to run both control and telemetry through a single cable. This dramatically reduces wiring clutter and makes installation cleaner, especially in complex aircraft setups.
