Last saturday, June 25th, around 4:45pm I went to my favorite open area to fly my Typhoon H. I started the ST16 first then the Typhoon H. Waited to get initialized then I suddenly noticed that the CGO3+ camera had a live feed way before the satellites on the Typhoon and ST16 did...my thoughts was like..."Wow! That's new!" Still satellites "Acquiring". Then came the "Ready" status. Checked all the satellites one more time... I have about 19. Turned on the motors... then I ascended to about 200ft. Everything was going well until, "VROOM!!!" My Typhoon H started flying away... and it was fast! Then the ST16 vibrated, "GPS Lost! Manual flight only!" PANIC TIME!!! "FLY AWAY!" Tried controlling it and it was not responding. Horrified! Still trying while moving the left and right stick...then I noticed the H was heading far away. OH NO!!! I told myself I better do something and quick. I turned the left stick again and suddenly very little I noticed it responded but was flying very wild. Tried again... and again... and again. And little by little I felt I was starting get more control. The H started to move towards me... but swaying very badly. Then I slowly lowered it down while trying to minimize the swaying until it finally landed. I shut the motors right away. Phew! My nightmare was over..Thank god! I checked the ST16 status and it never recovered the GPS. I checked the aircraft for any damage and there it was a hairline crack on the top cover caused by the violent movements in the air. The gimbal also sustained a tiny crack where the 4k cover resides due to my emergency landing in the dirt. Overall my Typhoon H was fine and we both survived the horror. Fast forward today, With my telemetry as my back up, Yuneec told me that they will take care of me. Moral of the story, always fly in an open space away from people because you'll never know when technology will fail. Also, if GPS is lost while flying you can still control it manually but it won't be easy. Don't give up and keep trying! You also have the telemetry on your ST16 as a record and your proof!
