Fly by app or by line of sight? So far I have only flown the P4 in bright outside conditions, and it was very hard to see the iPad display due to reflections, so I kept the P4 close enough to me so I could see the red lights, thus I would know which direction to move the sticks in relation to the red lights. Fun for a few flights, but I'd like to know what to look for on the display to determine for sure which direction I am flying and which direction to move the sticks to venture out a little bit. I did search this forum for answers but didn't find specific answers. Thanks for any help.
