LiteRadio 3 Radio Transmitter is the newest remote control in the LiteRadio series. This transmitter features an ergonomically designed handle and has superb performance in its working time, newly updated gimbal, and multi-protocol support (Frsky version). Besides, this version supports BETAFPV Configurator which is a utility designed to simply update, configure, and tune the radio controller.
The default firmware of the LR3 (ELRS 2.4G) has been ELRS V3 since Nov 2023 instead of the previous version, ELRS V2.0. If you want to upgrade your old radio transmitter, please check this guidance.
Note: After the new firmware is updated, the host computer can already display the external TX parameters, but these parameters have nothing to do with the external TX and are just false values set to enter the host computer faster, please check the firmware file links for Lite Radio 3 for more information.
LiteRadio 3 is a remote control radio transmitter designed primarily for RC models, including multirotor, airplanes. It gives you more than you ever thought possible from an entry-level 8-channel radio.
Reserving a nano bay on the backside, LiteRadio 3 supports an external module. BETAFPV ELRS Nano TX Module, which features a high refresh rate, ultra-low latency, and long-range, is strongly recommended to LiteRadio 3.
Note: The external modules should support the CRSF protocol when using other brands. If you are ready to install the TBS external nano module, the TBS nano module case size should be 64*42*25mm, the thicker one of the retrofit cases.
Compared with LiteRadio 2 SE, the LiteRadio 3 is equipped with a 2000mAh 1S battery, bringing an excellent endurance performance up to 15 working hours without an external module. Reserving a nano bay on the backside, it supports an external module for use with ELRS Nano TX Module, which supports CRSF protocol. Moreover, the LiteRadio 3 gimbal is newly updated with an accurate potentiometer and adjustable stick ends.
