I know how you feel. Man its a sick feeling in your gut. I had the same problem. I tried to raise it up about 2 or 3 feet to have it sit stable in front of me for a few seconds - but as soon as I raised it up it started to drift away and I couldn't pull it back and it crash into the water. It just took off on its own. A few people saw it drift away and they video it - I tried to pull it back but to no avail. It went down 20 feet in the lagoon. I fished it out and got it home and cleaned it and put into into rice for a few days but its dead. I contacted Yuneec today and they gave me an RMA and its on its way for evaluation. I had no control when it was moving away...none whatsoever and couldn't pull it back. I felt so helpless and in complete shock when it hit the water...I think I almost cried. I hope and pray Yuneec helps gets this resolved. I worked with Marelyn from Yuneec and she was very helpful.
I lost all control and couldn't for the life of me pull it back...it had a mind of its own.
