Have had this up and flying about 10-15 times. Fun unit to use, and a great stater pack. when flying outside be careful as the range of the transmitter isn't overly far. I lost signal Saturday and had to chase after it. Once in range I cut the throttle and it crashed in the woods. Spent the night in freezing temperatures and under 1.5 feet of snow. Found it the next day, dried it out and it's still working. I've crashed it in the house about 20 times and it's built so well that it hasn't had a problem. Suggest buying an extra battery as flight time is only about 6-7 min and waiting for it to recharge is no fun. I would also suggest buying an extra motor or two as people online have commented that they burn out pretty quickly.
