Bullet Point
- LiteRadio 2 SE upgrades with BETAFPV self-developed Customized LiteRadio System. Pilots can directly operate the Joystick Calibration and Firmware Update on the radio transmitter, which is more convenient for the beginner racer to operate.

- Comes with a built-in charging module, LiteRadio 2 SE can support USB charging which is more convenient to use. Meanwhile, it designs a Low-Power warning to indicate a low battery. While it needs to be re-charged(when the voltage is lower than 3.5V), the LED will turn red first, then it will turn blue and flash slowly.
- Compared with the LiteRadio 2, LiteRadio 2 SE has a larger transmitting power that can reach 100mW, bringing a wider operating range.
- Adopted the rubber coat, LiteRadio 2 SE is ergonomic and has the shape of a gaming controller. It's comfortable to hold, and the anti-slip texture on the handles allows for a solid grip.
- This radio transmitter acts as a USB Joystick when connected to a personal computer. So you could use it to play FPV simulators like EREADRONE.
- LiteRadio 2 SE transmitter has been equipped on the Ready-to-Fly FPV whoop racing advanced kit 2 and FPV whoop racing starter kit 2. It is one of the easiest ways to get into the FPV hobby.
