The opposite. Every new flight starts in GPS mode, whether the switch is in sports mode or not. You can't start a new flight in sports mode. You must switch out of sports mode and then back into sports mode.I rarely fly my MP around other than to just run the battery out after my Litchi waypoint missions. Because of that, I just haven't put it into sports mode, but even if I did, don't you have to start your flight in sports mode to get the full speed rather than switching it during flight? It seems like that was an issue at one time. If not, sorry for putting this out there.
