OK, there is no dispute that you had a significant problem. The motor state changes from 255 to 254. i don't know what the normal motor state is when all 6 are working. It might be 256, it might be 255. if it's 256 there might have been a problem at lift off. But I don't know the correct value for a 6 motor functioning state. There does appear to be a motor loss, and a whole lot of yaw, which is not what the H will usually do when losing a motor. The H did not drop straight down, it took about 9 seconds for the descent. We don't know why the H lost a motor, if that motor simply failed of if the H hit something that caused the motor failure, and perhaps caused the yaw instability.
I apologize for my earlier "takes care of" comment. That wasn't right. I purposely dropped the GPS location from the spread sheet. Sorry about the axis titles, I haven't yet figured out how to properly re-format the aircraft time column. Interesting that error flags did not occur until your H was halfway through its descent, and that "current" shows zero for the entire flight.
Shifting gears for a moment, you might want to pick it up from Staples and return it to Best Buy for an exchange. They may accept the RMA as reason for an exchange.
From still another direction, Staples appears to be consistently dropping the ball when handling Yuneec repair shipments. Staples does not handle any repairs directly, they seem to be a shipping agent or broker, likely due to the way the Canadian government/postal system handles and delays things passing back and forth to the United States. I have yet to experience a shipment that crosses the Canadian border that did not encounter long delays in the crossing process, with all the delay due to Canadian government/postal/customs regulations. The more people complain to Yuneec about delays through Staples the sooner Yuneec might separate from whatever agreement they have due to non performance and connect with someone considerably more responsive.
Think about this for a moment. Yuneec contracts with Staples to be the shipping agent for repairs. I seriously doubt there's any agreement for Staples to actually make repairs on Yuneec's behalf. Staples agrees to handle the shipments and takes responsibility for product movement. Perhaps Staples is waiting for Yuneec to provide shipping fees? Perhaps Staples is waiting for a monthy shipping date to come around. If Staples elects to sit on repair shipments for whatever reason, exactly what can Yuneec do about it? Do they fly up to Canada and physically take possession of the articles sitting in the Staples warehouse? Do they threaten Staples with various types of dire actions? Does Yuneec initiate a series of e-mails and phone calls with Staples? Do they put the product owner in that communication loop? Corporations typically keep customers in the dark if they are having trouble with vendors. Should Yuneec let the customer know they are experiencing issues with the shipping agent if that's the case? I would say yes, but I have not heard of that happening. So, is the problem Yuneec's or one that is more chargeable to Staples? I'd say Staples, with Yuneec bearing some of the blame for choosing a representative badly, but I don't have any info from either company to form an opinion with.
Another alternative is Staples is awaiting shipping/customs approvals from your government. We don't know what we don't know but I suppose it makes people fell better to blindly blame someone in a rant.
