ExpressLRS RX24T 2.4G Receiver

The ExpressLRS RX24T is a high-performance 2.4GHz radio frequency receiver designed for FPV drones, racing quadcopters, and remote-controlled aircraft requiring ultra-low latency communication. Professional drone pilots, FPV racing enthusiasts, and RC hobbyists rely on this receiver for its sub-millisecond response times and robust signal handling in competitive and demanding flight environments. This receiver solves the critical problem of signal dropouts and latency issues that can compromise flight stability and control responsiveness in high-speed aerial operations.

Product Overview

The ExpressLRS RX24T operates on the 2.4GHz ISM band using advanced frequency-hopping spread spectrum technology, which provides exceptional interference rejection and reliable connectivity even in RF-dense environments. The receiver features a compact form factor with integrated antenna options and supports multiple communication protocols including CRSF (Crossfire Serial Protocol), enabling seamless integration with modern flight controllers like Betaflight, INAV, and ArduPilot. Its architecture implements adaptive link rate switching, automatically optimizing bandwidth allocation between 25Hz, 50Hz, 100Hz, and 200Hz update rates based on signal quality and user preference.

What distinguishes the RX24T from competing receivers is its exceptional range-to-weight ratio, achieving reliable control signals beyond 50km line-of-sight while maintaining a featherweight profile ideal for weight-critical applications. The receiver incorporates telemetry feedback channels, allowing bidirectional communication that transmits RSSI (Received Signal Strength Indicator), battery voltage, and flight controller diagnostics back to the transmitter. Advanced failsafe mechanisms ensure predictable behavior during signal loss, with configurable options for throttle cut, GPS return-to-home, or stabilized descent depending on application requirements.

How to Use

Begin by identifying your flight controller's UART port and confirming compatibility with CRSF serial protocol. Connect the RX24T receiver to the designated UART RX pin (typically UART1 or UART3) on your flight controller, ensuring proper voltage regulation between 4.5V and 6V. Power the receiver through a regulated BEC (Battery Elimination Circuit) or dedicated power supply, avoiding direct battery connection that may cause voltage spikes. Configure your flight controller firmware to enable CRSF serial input on the corresponding UART port, setting the baud rate to 115200 and selecting CRSF as the receiver protocol in the configuration menu.

After hardware setup, bind the receiver to your ExpressLRS transmitter module following the manufacturer's binding procedure, typically involving a bind button press sequence on both transmitter and receiver. Configure link rate preferences in the transmitter settings based on your application: 200Hz for racing, 100Hz for general FPV flying, or 50Hz for long-range missions requiring extended range. Test failsafe behavior by walking out of range to confirm the configured failsafe action (throttle cut, RTH, or stabilized descent) engages properly. Monitor telemetry data on your transmitter display to verify RSSI levels, packet loss percentage, and battery voltage readings throughout your flight session.

Frequently Asked Questions

What is the difference between 25Hz, 50Hz, 100Hz, and 200Hz link rates on the RX24T?

Link rate determines how frequently the receiver updates control inputs to the flight controller. 200Hz provides the lowest latency and fastest response for racing drones but consumes more bandwidth and has shorter range. 100Hz offers balanced performance for general FPV flying. 50Hz extends range significantly with minimal latency loss for long-range missions. 25Hz provides maximum range for extreme distance flying but introduces noticeable control delay. Select based on your specific application requirements.

Is the RX24T compatible with my flight controller?

The RX24T uses CRSF serial protocol and is compatible with any modern flight controller supporting CRSF input, including Betaflight, INAV, ArduPilot, and Cleanflight. Verify your flight controller has an available UART port and confirm firmware support for CRSF serial input before purchase. Legacy flight controllers without CRSF support require additional serial adapters.

What happens if I lose signal during flight?

The RX24T implements configurable failsafe mechanisms that activate when signal is lost for approximately 1 second. Options include throttle cut (immediate motor shutdown), GPS return-to-home (if equipped), or stabilized descent. Configure your preferred failsafe mode in the transmitter settings before flight to ensure safe recovery behavior.

Can I use the RX24T with my existing 2.4GHz transmitter?

The RX24T requires an ExpressLRS-compatible transmitter module. It is not backward compatible with standard FrSky, FlySky, or Spektrum 2.4GHz transmitters. You must use an ExpressLRS transmitter module or upgrade your existing transmitter with an ExpressLRS module.
