This Iris F154 frame is specifically designed for lightweight, quite and agile 3.5″ and 3″ toothpick builds. Fits 25.4mm x 25.4mm mounting pattern AIO board, 9mm x 9mm mounting pattern motors. It only weighs 18.6g, with four arms+ two plates and hardware. The separated arms design makes it easy and cheap to maintain. Dedicated room is reserved for you to tuck the battery strap through the frame, so your build looks much cleaner. Carefully crafted DJI O3 air unit mount makes the air unit fit perfectly on this X configuration frame.
Tip for frame assembly: we highly recommend using medium strength threadlocker during screw installations, this could prevent the screws from loosening during flight.
