Support IRC Tramp Protocol: Ultra3000 VTX supports the IRC TRAMP protocol and the modification of video transmission parameters through the remote control, including frequency, working power and so on. NOTE: For BetaFlight flight controller firmware above BetaFlight 4.1.0, you need upload a VTX Table to the flight controller before using the remote control to modify the video transmitter parameters normally. WARNING: 1. Install antenna before use. 2.To prevent overheating, provide constant airfiow and a well ventilated environment.Install a cooling fan if operating in confined conditions. 3. The 5V Output is just used for a Camera/Cooling Fan Don't connect Power Input / Battery to 5V Output port. Otherwise the VTX will be damaged. Package included: 1 x Ultra3000 VTX 3W 1 x MMCX connector to SMA connector 82cm 1 x GH 1.25-6P connector cables 150mm
