We bought a R/C UFO # 243 from a EBAY vendor via auction. The item is made by Big Tree toys  in China. The item was very cool looking the way the video was showing it. We tried it three times . With some success we did get it to fly. The big problem was the battery pack. On the fourth charging the battery pack that was left unattended exploded  and caught fire. We were very lucky that we were home and awake. This  item is not safe.
