Hello, I own the Phantom Vision 2 Vision+ I havn't flown my Drone for about a month, and store it inside my house. The other day I went outside to show my relatives visiting for Christmas, after all the great talk on all of it's features and capabilities, I take it outside (23 Degrees out - Minnesota) and everything went fine untill I unlocked the blades to start, one blade spinned fine, 2 were real slow to start - taking several seconds to get up to speed, and the last blade turned slow and didn't get spinning fast enough. So I turned the blades off, and thought wierd, lets try this again, same thing happened. All this great talk to my family then I take it out to fly and it doesn't even leave the ground. Bummer. Does anyone know a fix to this problem? I asked the guy I purchased it from (who is somewhat knowlegeble and into them) and he said it could be the ESC Board, which I guess controls the Motors. Any other thoughts or fixes? Is this something I can fix on my own? Or do I need to send it in? Any information will be much appreicated! Thanks!
