After DJI "fixed" my quad because of stress cracks around the rear motor mounts and sent it back to me a few days ago, I inspected it yesterday and noticed this crack on the arm after just a few flights! And this crack is on the arm itself and not in the screw mounts. All 7 flights were flawless and the landings were all hand caught. I handle and treat my quads like a new born baby! The old "flawed" shell lasted much longer than this. Man...this is ridiculous! Anyone else had a new and improved shell crack?
