O4 vs O3

Right here’s a comparability desk between the DJI O4 Professional and DJI O3 Air Unit:

* DJI’s FPV programs are recognized to have a tough vary restrict, which is expounded to software program constraints relatively than {hardware}. The precise arduous restrict for the DJI 04 Air Unit is at present unknown. The claimed most vary for the Avata 2 (which additionally makes use of the O4) is 13 km, however I believe it can exceed that. For reference, the DJI Avata (V1) utilizing the O3 system is marketed at 10 km however has a real-world arduous cap of 23 km. Testing the true vary of the O4 system with the Avata 2 isn’t possible as a result of its battery gained’t final lengthy sufficient for such distances. We’ll have to attend for additional testing after its launch to verify.
