Bought 1year ago , been sitting on shelf afraid to fly it because of all pepole saying fly aways spent 1000.00 surfing cell phone . I think it got 1. Something soft ware in it , now with all the new updates I think there up to 3. Something . I charged battery, it's four green led. Charged repeater it's green. New battery's in controler it's green . I don't own a computer so I can't update it , can barely operate this smartphone, it's smarter than me. Some pepole said when dji did the updates theirs quit working. Is that my problem. Firmware updates, they said rtf , I guess if your a computer wiz, it is ready to fly.
