Hi again everyone,
Closing my post on this issue. I got my replacement bird this week. I appreciate the customer service from Yuneec Germany, but even more the support from Peter at Yuneec Russia! Serious approach and good service.
Regarding root cause for the crash I did not get much from Yuneec, except that the crash was related to some kind of power outage. This is more or less the same conclusion as some of you guys out there came to.
Again, I am happy for the professional and non-biased support!
