AOS 3.5 O3 FPV Frame Kit


Built to go toe to toe with 5" Freestyle quads whilst weighing under 250g. The AOS 3.5 O3 has been updated to be compatible with the new DJI O3 Air Unit as well as existing 20x20mm and 25.5x25.5mm electronics. The camera cage and arms have been reinforced to improve durability.
