ATTI mode loses nothing to Sport mode as far as speed goes. If you see my post above you can still hit 40 MPH in ATTI just like in Sport so the ability to cope with wind does not decrease.I would have to respectfully disagree. Sports mode has got me out of one or to jams when the wind picked up suddenly and also near sunset when the sensors wouldn’t let me fly forward. I would say that having a att mode button would also be handy in certain situations. Like flying in a big warehouse or gym.
