New user awaiting arrival of a P3 Adv. I've been watching so many video and reading everything available my head is spinning. Seriously though one thing I can not find a straight answer on is while in F-mode is GPS and Vision Positioning available? Or is this basically Atti mode with advanced feature controls? I know A-mode (attitude) does not use either of the 2 stabilization methods but have not found if F-mode uses them. I tend to think F-mode would use the 2 stabilization methods otherwise A-mode wouldn't make any sense having it's existence. People could just use F-mode and don't use the advanced IOC features it offers. Newb must be missing something. I don't plan on jumping right into those features anyway. I just want the best full understanding I can have and slowly work my skills up with patients. I do have a few other questions if anyone care to be of assistance and thank you very much.
