Now with team racing capability! Easy OSD, FC and RC channel changes, with back button menu. Robust RF amplifier allows powering without antenna for hours!Clean power on and video switchingCE Certified, PitMode - Made to raceZero interference even while on, now a possibility! If you've ever serviced a quad during a race, you know the frustrations of not being able to power up and test your system. With PitMode, we will reduce the output power to a minimum (well below single digit mW) to allow you to turn on your quad and still see the image. You have less than a meter of range to put your quad through its paces before placing it on that starting grid. With SmartAudio or CRSF, you can turn on the VTx with your remote control. SmartAudio V2.1 and CRSF - Team Race ReadySmartAudio technology provides UART control for your entire video transmitter. Parameters such as output power, bands, channels and frequency can be controlled freely. This allows remote control of the channel directly from a smart device (TBS Crossfire, external Bluetooth module or Wi-Fi required), from your radio (TBS Crossfire with TBS Tango or OpenTX compatible remote required), or from the OSD (e.g. example, Betaflight OSD, TBS CORE PRO). With all of these options available, you should find something that fits your bill. Together with CleanSwitch, the sky is the limit... jump between channels without interfering with other pilots in the air, create backup/emergency frequencies, global VTx power adjusters
