Buying Guide: BETAFPV LiteRadio 3 FPV Transmitter
The BETAFPV LiteRadio 3 is a practical entry-level radio for pilots who want to start FPV without spending heavily on a full-size transmitter.
Its biggest advantage is not simply the price. The Nano Module Bay gives LiteRadio 3 more upgrade potential than the older LiteRadio 2, while the 2000mAh battery provides much longer operating time than the original LiteRadio 2 platform.
MEPSKING Expert Assessment
For a beginner, the most important features of a transmitter are simple control, reliable connection and easy simulator training.
LiteRadio 3 provides an 8-channel layout, built-in 2000mAh 1S battery, USB-C charging and simulator support. The ELRS 2.4G version can be used directly with compatible ELRS receivers, so a new pilot does not necessarily need to purchase an additional external module.
The Nano module bay is particularly useful for users who want more flexibility later. BETAFPV recommends its ELRS Nano TX Module, and the bay can also accept compatible external modules using CRSF.
This makes LR3 a good middle ground: simpler than a full EdgeTX radio, but more upgradeable than the older LiteRadio 2.

Why Choose LiteRadio 3?
The main reason to choose LiteRadio 3 instead of LiteRadio 2 is the additional flexibility.
LiteRadio 3 includes:
● 2000mAh 1S battery
● Nano module bay
● 8 channels
● ELRS 2.4G option
● USB simulator support
● BETAFPV Configurator support
● Upgradable gimbal options
The Nano module bay is especially valuable for a beginner who may start with the internal ELRS system and later want to experiment with another compatible external TX module.
For someone buying their first FPV transmitter, that makes LR3 more future-proof than the original LiteRadio 2.
LiteRadio 3 for FPV Simulators
LiteRadio 3 is also useful before buying a complete FPV drone.
It supports popular simulators including VelociDrone, Liftoff, TRYP, DRL, DCL and DJI, and firmware updates have added compatibility with Android devices and DJI's Windows virtual flight software.
For a beginner, this is important because simulator practice allows you to learn throttle control, turns and orientation before putting a real drone at risk.
Compatibility
● For the ELRS version, use it with 2.4GHz ExpressLRS receivers.
● Confirm that the drone's receiver protocol matches the transmitter before purchasing.
● The Nano module bay supports compatible external TX modules; third-party modules should support CRSF when used with LiteRadio 3.
● LiteRadio 3 supports USB simulator operation and firmware/configuration through BETAFPV Configurator.
● If upgrading the gimbals, use the compatible LiteRadio Nano Gimbal. BETAFPV offers both potentiometer and Hall versions for LiteRadio 3.
MEPSKING Purchase Verdict
Buy the BETAFPV LiteRadio 3 ELRS 2.4G if you want an affordable FPV transmitter with built-in ELRS, a 2000mAh battery and a Nano Module Bay.
Choose LiteRadio 2 only when the lowest-cost basic controller is the priority. Choose LiteRadio 4 if you prefer newer features such as 10 channels, Bluetooth simulator connectivity, trim switches and fast charging.
In short: LiteRadio 2 for basic entry, LiteRadio 3 for upgrade flexibility, and LiteRadio 4 for the newest features.
