Understanding the fit
Recommended fit for this frame. Check the installation notes below.
Can be installed, but may require your own custom or 3D-printed mounts. Not an officially supported mounting solution.
Not compatible with this frame.
Installation notes
DJI Air Unit (Original)
Refers to the original, first-generation DJI FPV Air Unit, not the DJI O3 or O4 Air Unit.
HDZero Freestyle V2
Compatibility ratings apply to the Freestyle V2 VTX only. The Freestyle V1 VTX does not fit these frames.
Walksnail
Compatibility ratings apply to the Walksnail Avatar Moonlight, Avatar HD Pro, and Avatar HD models.
O4 installation
For the best fit, we recommend the O4 Wide paired with a camera adapter mount.
O4 camera cable
The stock camera-to-VTX cable is too short. Replace it with a longer compatible cable.
