With the new update, the St16 also records your flight, so you can watch the video and see where the H was last in the air.
I was recently filming wildlife in a marsh surrounded by trees. I temporarily lost my signal, the H drifted another 50ft or so and started RTH, when that happened it was under the edge of some tree branches, it knocked out a prop just as my signal returned, I received a 5 motor error and the H landed in the swamp. The video on the ST16 gave me the last location which was off by 50-75 feet due to the drifting. After wading about 2 hours through the 3ft swamp with another 12-15in of black muck on the bottom I was fortunate to find the H buried in the muck. It only had a broken landing gear and two broken rotors, but is was completely filled with the tar like muck.
I was flying approx. 900ft away when I lost the signal and I have flown previously out to 3200ft with the stock ant. I had recently updated the firmware and after the crash I read numerous people had signal reduction since the update. I called Yuneec, explained what happened and the stories of signal loss since the update. They immediatley emailed me a RA number and the bird was shipped to them the next day. They received it this past Monday and on Wednesday Yuneec notified me that a NEW H was being shipped to me on Thursday. They are not only sending just the bird, they are sending a completely new system, Original box with Remote Wand.
I hear complaints on Yuneec's customer service, however, since my purchase three months ago, I have always had quick and excellent service from them, and this last experience puts them over the top.
The only complaint I have is the signal loss with the update. The update did provide increased speed, St16 recording and playback, and other features. We will see what firmware is on the new system.
Sorry for the lengthy post, but I wanted to point out the signal problem with the update as well as the customer support Yuneec provides.
