This fresh new 3.5″ frame is specifically designed for lightweight, quite and agile 3.5″ 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. 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.
