BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G
From Simulator to Real Drone with the BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G
The BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G is a gamepad-shaped radio with a built-in ExpressLRS 2.4G transmitter, designed with beginner FPV drone pilots in mind. It works in Mode 2 (throttle on the left stick), has 8 channels and 4 switches, and transmits at up to 100mW. It ships with ELRS V3.0.0 firmware, so it works with ExpressLRS 2.4G receivers running version 3.x. The built-in 1000mAh 1S battery lasts about 8 hours and charges over USB-C. Through the same port you can connect the radio to a Windows computer or an Android device and fly in simulators such as VelociDrone, Liftoff or DJI Virtual Flight, and update or configure it in BETAFPV Configurator.
BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G Key Features
Long Battery Life
The built-in 1000mAh 1S battery lasts about 8 hours. You can get through several flying and simulator sessions on a single charge.
Easy Charging
You charge the radio with a USB-C cable from a 5V charger. There is no separate charger or spare battery to carry, and the LED and buzzer remind you when the battery runs low.
Familiar Grip
The gamepad-shaped body has a rubber coating with an anti-slip texture on the handles. It sits securely in your hands, so it is easier to focus on flying.
Simulator Practice
It works with VelociDrone, Liftoff, TRYP, DRL, DCL and DJI on Windows and Android. You practise with the same radio you will later fly a real drone with.
ExpressLRS Link
A built-in ELRS 2.4G transmitter with up to 100mW of power, shipped with ELRS V3.0.0 firmware. No external module is needed, just an ExpressLRS 2.4G receiver running version 3.x.
Easy Configuration
Updates and settings are handled in BETAFPV Configurator on Windows, macOS and Linux. You can even calibrate the sticks without a computer, using the SETUP button on the radio.
One Controller for Many FPV Simulators
Connect the radio with a USB-C cable to a Windows computer or an Android phone or tablet and practise in simulators such as VelociDrone, Liftoff, TRYP, DRL, DCL or DJI. In Joystick mode the system sees it as “BETAFPV Joystick”, and Xbox mode lets it work with DJI Virtual Flight on Windows.
Updates and Settings in BETAFPV Configurator
BETAFPV Configurator is an open-source program for Windows, macOS and Linux for updating, configuring and fine-tuning the radio. You use it to flash new firmware, check the firmware version and change the channel settings, all over a regular USB-C cable. Connect the radio to the computer while it is switched off, otherwise the USB port will not work.
As Comfortable as a Gamepad
The gamepad-shaped body is covered in rubber, and the anti-slip texture on the handles gives you a secure grip. You charge the built-in battery over USB-C, and when the voltage drops below 3.5V, the LED and the buzzer remind you to recharge.
Frequently asked questions - BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G
According to the manufacturer, yes. BetaFPV states that it designed the radio with beginner RC pilots in mind and supplies it as the radio in its Aquila16 and Cetus series ready-to-fly FPV kits. The manufacturer also says the gamepad shape and simulator support make learning to fly easier.
With ExpressLRS 2.4G receivers. The radio ships with ELRS V3.0.0 firmware, so the receiver needs to run the same major ELRS version (3.x).

- After about 5 seconds the LED ring turns solid blue again. If binding failed, repeat the steps.
Stick Calibration
- After switching on, press the SETUP button on the back; the red LED flashes quickly and the radio enters calibration mode.
- Centre both sticks and press SETUP again; after three beeps the centre position is saved.
- Move each stick to its top, bottom, left and right limits, holding each for 1-2 seconds, then press SETUP once more; a long beep means calibration is complete.
BetaFPV LiteRadio 2 SE Radio Transmitter Mode 2 ELRS 2.4G Manufacturer Warnings
The notes below come from the manufacturer, from the BetaFPV user manual and product page.
- The receiver must run ExpressLRS 2.4G in the same major version as the radio, which ships with ELRS V3.0.0 (version 3.x).
- Before connecting the radio to DJI Virtual Flight, make sure its firmware is V24.11.8 or newer.
- A solid red light at power-on means the throttle stick or the switches are not in the lowest position. Move them down and the light turns blue.
- Do not switch the radio on before connecting it to a computer. If it is already on, the USB port will not work.
- When the radio is switched on, there is no signal output from the USB port, so Joystick mode and Xbox mode will not work.
- If the cursor moves after connecting the radio to a Windows computer, set the three-position switch to the middle and the two-position switch to the lowest position.
- If the radio cannot connect to a computer with an AMD processor, or the low-voltage alarm does not sound, the manufacturer recommends flashing the latest firmware.
- If BETAFPV Configurator cannot connect to the radio, check that the radio was switched off before connecting, that the USB cable supports data transfer and, on Linux, that CDC or HID access is enabled.
- After a period of use, especially if the sticks take a hard knock, the stick values may drift. Recalibrate them with the SETUP button, and do not press the sticks hard against their limits during calibration, they only need to touch them.
- When the battery voltage drops below 3.5V, the LED and the buzzer signal a low battery. Charge the radio then.
- Charge the radio switched off, through the USB cable from an adapter with a 5V output.
- Risk of explosion if the battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.
- The manufacturer is not responsible for any radio or TV interference caused by unauthorised modifications or changes to this equipment. Such modifications could void the user's authority to operate it.
- Belt clips, holsters and similar accessories used with the radio should not contain metal parts, otherwise the RF exposure requirements may not be met.
