I am the second owner. I do not know the detailed history of the flight status or crashes. The last flight was on October 13th. After I obtained the aircraft, I set up the transmitter and receiver and flew it about 10 times. It can fly without any problems in auto-return, GPS mode, and 3D mode. When flying in GPS mode, even those who are new to operating a radio-controlled helicopter will rarely crash due to operational errors. Landing is automatic, returning to the place where it took off with the flick of a switch. The transmitter was purchased used, and the base of the carrying handle was broken when I bought it, so I repaired it. There are no problems with its strength. Also, the sticks are full-spring type, which is often seen on drones. I will explain the switches in detail after you purchase it. The included LiPo battery is a 4-cell 5000mAh. It can fly for about 20 minutes if you are just practicing hovering, but a 4-cell 2200mAh is recommended for increased maneuverability. All included parts are new. There is also a full metal head. Please be sure to ask any questions you may have before purchasing.
