LiteRadio 2 SE Radio Transmitter is the upgraded version based on LiteRadio 2 and comes with huge improvements.

Built-in 1000 mAh 1S battery, LiteRadio 2 SE increases the endurance to 8 hours.

Pilots can directly operate the Joystick Calibration and Upgrade Firmware on the radio transmitter.

Supports the Frsky / Futaba / Bayang, pilots can easily change Futaba, Frsky D8, Frsky FCC D16 and Frsky LBT D16 mode via the radio transmitter.

Comes with 100mW transmitting power, LiteRadio 2 SE brings a wider operating range.


Bullet Point

LiteRadio 2 SE upgrades with 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.

Equipped with a built-in 1000 mAh 1S battery, LiteRadio 2 SE can use up to 8 hours, bringing an excellent endurance performance. 

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 hobby.
