Re: which setting S1 should i practice manual flying (no gps
In manual mode, the craft WILL NOT right itself, as you add roll, it keeps going (able to do a loop if you want). Practice LOW, over soft grass or sand/plowed earth. Landing is a bear. Use a LIGHT touch on the controls.
Keep in mind that when you switch to manual mode, the throttle will instantly drop (and so will the Phantom). Be prepared and give it some positive climb (up on the left stick) as you throw the S1 switch down. Releasing the throttle to neutral will cause an immediate descent.
It ends up being HIGHLY responsive and controllable, and is FUN to fly, but operator error is NOT forgiven. If you are losing control, just through the S1 switch back into ATTI or GPS mode.
Good luck.
