Atti mode is challenging more so if you where really high up and with wind, could be a challenge for someone with experience in flying too , I would get a cheap drone to learn to fly on first , one of my friends told me about his gps went off and entered to Atti mode, he had some experience in flying but was took by surprise he couldn't control it , he said there was some wind but he had it out in the dark which probably wasn't a good idea ,
