This updated version of the FrSky VS600 VTX has several innovative features such as the new "Pit mode" which lowers the VTX power output to less than 0.001mW where the user can test their FPV equipment without interfering with other pilots. It has a built in microphone, allowing for audio feedback. Setup is easy with a single button and 3 LEDs and your settings are saved on shutdown so there's no need to worry about fiddling with them every time you fly. If paired with a FrSky transmitter, you can even adjust the settings and parameters using your transmitter's gTrans.lua. This can also be done using FreeLink on your PC or via Bluetooth via the FreeLink App in conjunction with the FrSky S.Port AirLink S. It's compact form factor means it can be placed anywhere you like using the four, 13mm spaced mounting holes and the IPEX 4 antenna connector makes for easy removal for cleaning or maintenance.
