I am new too all this flying as well flying 2 syma's a x5 and a x25 I have never tried the headless mode I have learnt so far using LOS I am thinking about painting my front legs or a something to see the front at a glance couldn't hurt fpv through the phone is fair but lots of lag and glare on the screen but the biggest aid to me is alt hold and gps positioning at least now when I get into trouble I can stop and get my act together unlike earlier on with the x5 its a manual animal and you have to keep on top of it
