BetaFPV LiteRadio 4 ELRS 2.4GHz Controller
The BetaFPV LiteRadio 4 is a compact, 10-channel radio controller designed to control FPV drones, RC models, and other compatible devices. Equipped with the ExpressLRS 2.4GHz system, it enables precise control while maintaining a compact size and comfortable operation.
The controller combines the functions needed for real-world flights with the ability to practice in simulators. Thanks to Bluetooth and USB support, it can also be used as a controller for FPV flight simulations on compatible devices.
The built-in 1S 2000 mAh LiPo battery, adjustable transmission power, and ergonomic design make the LiteRadio 4 a practical solution for both beginners and users looking for compact equipment for daily training.
Key Information
10 control channels
BetaFPV LiteRadio 4 offers 10 control channels, providing the ability to operate the model’s basic functions as well as additional settings assigned to switches.
This solution allows the transmitter to be used not only for flying FPV drones, but also with compatible model airplanes, robots, and other radio-controlled vehicles.
The compact layout of the controls makes it easy to access the most important functions without the need for complex equipment.
ExpressLRS 2.4 GHz
The controller uses the ExpressLRS radio system operating in the 2.4 GHz band. This solution is used in RC modeling and FPV drones and is designed for low-latency transmission of control commands.
LiteRadio 4 allows you to select a transmission power of 25 mW, 50 mW, or 100 mW, enabling you to adjust the configuration to your operating conditions and applicable regulations.
A compatible ExpressLRS 2.4 GHz receiver is required to operate the device. Before connecting the devices, verify that their configurations and software are compatible.
Gimbals and Control Adjustment
The Standard version of the LiteRadio 4 is equipped with potentiometric gimbals, allowing for smooth control of the model’s individual axes.
The stick design is built for regular use. The controller also features adjustment controls that allow you to fine-tune the controls when operating compatible models.
Additional trim switches make it easy to make adjustments without having to interrupt control. This is especially useful when learning to operate the equipment and configuring RC models.
Wireless Training in FPV Simulators
The BetaFPV LiteRadio 4 supports Bluetooth connectivity, allowing you to use the controller as an input device in compatible flight simulators.
This solution allows you to practice stick control and perform maneuvers without having to fly an actual drone. Training in a simulated environment is particularly useful when learning the basics of FPV control.
The controller also supports a wired USB connection, providing an additional option for use with a compatible computer or device.
Built-in 2000 mAh battery
The controller is equipped with a built-in 1S LiPo battery with a capacity of 2000 mAh, which allows you to use the device without the need for separate batteries.
The claimed operating time is up to 8 hours at 25 mW and approximately 4–5 hours at 100 mW. Actual operating time depends on settings and usage conditions.
The USB-C port supports charging at 5 V and up to 3 A. According to the product specifications, a full charge can take approximately 40 minutes when using a compatible power source.
Compact and Portable Design
The BetaFPV LiteRadio 4 measures 172.5 × 118.5 × 72.5 mm and weighs approximately 210 g. Its light weight and compact size make it easy to transport and use in various locations.
The ergonomic layout of the controls allows for comfortable operation of the sticks and switches during flights and training in simulators.
The controller can be a practical solution for pilots looking for equipment that is easy to transport and doesn’t take up much space in their FPV gear bag.
One controller for both training and actual flights
The LiteRadio 4 allows you to use the same equipment both when learning in a simulator and when controlling compatible RC models.
This allows you to practice using the control sticks and get a feel for their characteristics, and then use the same control layout when flying a real drone.
This is a practical solution for beginner FPV pilots who want to gradually develop their skills without having to switch controllers between training and flight.
Use with Various RC Models
The 10-channel design of the BetaFPV LiteRadio 4 allows the controller to be used in various configurations requiring radio communication.
The device can be used to control FPV drones, model airplanes, robots, and drone soccer rigs.
The controller’s usability depends on receiver compatibility, channel configuration, and the specific model’s requirements.
Adjustable transmission power
The controller allows you to select one of three output power levels: 25 mW, 50 mW, and 100 mW.
The power setting affects the transmitter’s power consumption and operating parameters. At 25 mW, the declared operating time is longer than at the 100 mW setting.
Transmission parameters should always be selected in accordance with the device’s capabilities and the regulations in effect at the location of use.
Standard Version – Potentiometer Gimbals
The LiteRadio 4 controller offered here is the Standard version, equipped with potentiometric gimbals.
The LiteRadio 4 family also includes the Twilight variant with Hall-effect gimbals. These are different variants, so when comparing offers, please pay attention to the exact product designation.
The offer with ID 33809 is for the BetaFPV LiteRadio 4 ELRS 2.4GHz controller in the Standard version.
A Convenient Start with the ExpressLRS System
The BetaFPV LiteRadio 4 combines 10 control channels, the ExpressLRS 2.4GHz system, Bluetooth and USB connectivity, and a built-in 2000 mAh battery.
This allows it to serve as the primary equipment for your first FPV flights, as well as a tool for regular training in compatible simulators.
Its compact size and intuitive control layout make this model a practical choice for users looking for a portable RC controller.
