Help - I have been using the Phantom Vision 2+ with no issues for the last 3 months. I did the firmware upgrade this morning to 3.08 and I cant get it to fly. Everything seems to be fine - motors start - full connectivity - compass calibration etc., but as soon as I try to "take off" it is like the motors arent strong enough to fly. Left joy stick controls seem to be fine, but right control stick wont elivate the quad copter. Anyone had this problem? If not, does anyone know how to revert back to the previous firmware? Thanks in advance for your help!
