TODAY IS 15-20 MPH WINDS WITH GUSTS TO 35 MPH NEAR CHICAGO I took off and went up to 120 feet and the mavic was cruising into the wind at 4mph max speed attained, then dropped to 1 mph I put into sport mode a warning came up about sport mode wasn't sure what it said I then returned the craft it buffered quite a bit and was losing its location lock sliding sideways but all and all it was still in control my best guess is 22 mph winds but don't move or it will not make it home it cant fly faster than the 22 mph head wind sport mode didn't make it faster or I was just cautious
