I flew my phantom today at a event at a High School. I flew it fast high up and when I brought it fast back down it wouldn't respond to my control. Half way it started to wobble with the wind and it crash in the middle of the event on concrete floor. I'm very lucky that no one got hurt. But I'm very shock that it crash and it didn't respond to my control. I was flying for only 5 mins when it happen. The battery was loaded. This is the 2nd time it happens. When bringing down it wobbles and Lost contact. When it crash the 3d Gimbal came apart. Luckily Everything is still working. Does anyone experience similar situation? I have a phantom 2 with 3D gimbal.
