SPIDER Automation | BETAFPV LiteRadio 3 FPV Radio Transmitter – ExpressLRS 2.4GHz, 8 Channels | Ergonomic Control, Nano Module Expansion & Extended Battery Operation
Product Overview & Radio Control Design
The BETAFPV LiteRadio 3 is an 8-channel radio transmitter developed for controlling RC models, including multirotor and airplane platforms. It combines an ergonomic controller-style housing, an updated joystick gimbal design, and support for the ExpressLRS 2.4GHz protocol in the specified version.
The transmitter features a built-in 2000mAh 1S battery designed to provide up to 15 hours of operation without an external TX module. Its integrated charging module supports USB charging, while the low-power warning system uses LED and buzzer indications to alert the operator when the battery needs recharging.
For configuration and maintenance, LiteRadio 3 supports the BETAFPV Configurator and BETAFPV’s customized LiteRadio System. These tools support firmware updates, transmitter configuration, and joystick calibration. The transmitter can also function as a USB joystick for compatible RC practice simulators.
An integrated Nano module bay allows the use of an external TX module. BETAFPV recommends its compatible ELRS Nano Module, which makes the CRSF protocol available when used with the appropriate module.
