A friend of mine luckily got an Inspire 1 on Saturday. He is very experienced in flying his Phantom 2 and is looking for an upgrade. Last night, he flew a bit his Phantom 2 just for demo of selling his machine to a potential buyer. Everything was alright as he flew at that location very frequently. About 30 minutes later, he enjoyed his Inspire 1, just for 10 seconds, at about 3-4 meter height, the Inspire 1 flew at its will. Totally lost control. A moment later it dropped and hit the ground, with the gimbal detached, camera broken, and all motor stop functioning. All pre-flight checking done. 9-10 satellites, compass calibrated, experienced flyer. He is reporting the case to DJI. See how they respond.
