OpenTX comes with a computer-based graphical user interface, OpenTX Companion, that runs on Windows, Mac OS and Linux. First, please download the OpenTX Companion file and install it in your computer. Please DO NOT use the original version. https://github.com/BETAFPV/opentx/blob/LiteRadio/companion/ companion-windows-2.2.4.exe How to connect the transmitter to the OpenTX Companion: 1. Press and hold the SETUP button from the back of the transmitter. 2. Press the power button on the transmitter. And then release both buttons. The LED ring will not power on . 3. Connect the transmitter to the computer via a USB cable. 4. Open the OpenTX Companion software. 5. Set the radio type to Lite Radio in the settings page. As show below. Do not forget to press the OK button at the end of this tab. 6. Press the second button on the left column to read models and settings from the radio. If you get a document dialogue as show below. Congratulate, connect successfully. The frequent usage of the OpenTX Companion is trim the gimbal central value. For example, You find the center value of the gimbal on the roll axis is 1525 in the Betaflight Configuration. The central value of the gimbal in the range of 1500+-5 is normal. 1. Click the Edit Radio Settings in the dialog above. In the pop new dialog, choose the Calibration tab. As show below. 2. Calculate the calibrated Mid Value according to the equation below. Calibrated Mid Value = Original Mid Value + ( Betaflight Configuration Mid Value - 1500) * 2 Calibrated Mid Value = 1010 + (1525 - 1500)*2 = 1060 3. Update the Ail (Roll) Mid Value to 1060 and click the Write Models. button in the end of the tab. The table above is just for the Mode 1 ( right hand throttle). So if you have a Mode 2 radio transmitter (left hand throttle), if you want to calibrate the pitch value, you must change the Mid Value in Throttle row. 4. Now back to the Betaflight Configuration, confirm if the gimbal calibra tion works. FAQ Q: What is the expected range from the LiteRadio V2 transmitter? A: The average output power is about 80mW on the transmitter. Also the valid range of the radio transmitter depends on the receiver. This is our testing use this LiteRadio V2 transmitter. Q: Is it possible to flash the radio to a different protocol? If I want to try D8 or Bayang instead? A: No. We should change the RF components in the transmitter for a different protocol. Q: Is it possible to change radio to mode 1 from mode 2? A: We think it is not easy for customers to change the mode. Need some modification. We should open the transmitter covers and exchange the gimbals first. Then we should update the configuration via the OpenTX Companion. So NOT recommend.
