Holybro Kopis Mini: Srinked size for DJI Air Unit

Holybro Kopis Mini DJI version

Holybro’s new Kopis MINI racing drone was specially designed for DJI’s digital FPV system and it follows the design of the older Kopis 2. It is available with or without on-board DJI Air Unit. The price difference between the two versions is about $US150.

By default, its versatile Kakute F7 HDV flight controller comes with BetaFlight firmware, but it can be flashed with ButterFlight and CleanFlight software as well. The F1507 KV3800 motors are driven by a 4-in-1 45A ESC board.

  1. Do you know if the Kopis Mini can be equipped with different camera and VTX. DJI’s FPV google is too expensive for most of us….

    • Yes, there is “Kopis Mini Analog VTX Version” with Foxeer Micro Razer 1200TVL camera and Holybro Atlatl HV V2 VTX. You have also option for FrSky radio receiver in bundle!
      Price difference between Digital HD and VTX is about 70 euros
