Maybe good thing you did not turn the GPS off manually, when checking my telemetry here in Europe, Yuneec Germany said that when flying without GPS, you are no longer covered by warranty. Might be different in a case like yours where you obviously lost control first.
It should be obvious in the telemetry to tell the difference between 1. losing control because you turned off the GPS and 2. disabling GPS because you lost control.
One would think that they respect the decision to turn off the GPS to try to save the aircraft and avoid accidents.
Here is the quote from the manual:
"We do not typically recommend disabling GPS for any reason,especially if you’re a first-time or low-time pilot. However, if you’re an experienced pilot that’s able to properly control Typhoon H in Angle
(Pilot) Mode, you can disable/turn off GPS. Do NOT disable/turn off GPS unless you accept ALL responsibility and liability for crashes or ‘fly aways’."
So, that leads me to a few questions and comments. I would almost say that if you are under warranty and do lose GPS, and are at no risk to cause injury to someone or something, let it crash. If Yuneec is THAT confident in their GPS, let them take the responsibility of it. (It also says several times "IMPORTANT NOTE:Crash damage and ‘fly aways’ are NOT covered under warranty." So maybe they aren't THAT confident in their GPS). I am being a little sarcastic in this and I dont think I would actually be able to just let it crash, but if it is true that turning off the GPS for any reason will void the warranty, then well?
Is disabling GPS mid flight (in case of a GPS loss) really necessary? If you do lose GPS while flying, what actually happens to your control of the aircraft IF you do not disable GPS? You would hope that if you see the "GPS lost. Maintain manual control of aircraft" message, you should be able to do just that and not have to worry about disabling GPS. The manual only says you can only control it in angle mode. It makes no mention that disabling it is the only way you can control it in angle mode.
