I have to say probably the most fun I have had in awhile I even broke 200ft once LOL, you guys that fly 2,3,400ft are crazy :shock: A couple of newbie questions though: 1. I stop flying when the low battery alarm goes off at about 30% I then proceed to charge the batteries. Should I be draining them a 100% and if so, how? 2. Same with my WIFI extender, when should you recharge that? 3. What are the default functions of the s1 and s2 switches? I know the left one switches from GPS to ATTI mode what does the other do? 4. Home Lock- I turn on radio, WIFI extender, then Phantom, I wait for slow to solid green and verify that it sees more then 8 sats, been get 11-13 regulary. How do you know you have a good Home Lock position? 5. Fail Safe - I understand that if I lose communication it should fly back home...is there a way to initiate RTH manually? Thanks for the help!!
