I have a x8 AUW 13lbs, with t motor 4014 motors, 16inc prop 6s batt x2, wkm flight control, Ok, m problem is it takes off fine I bring it to a hover and all of a sudden out of know where , it acts erratic , side to side rocking very fast, scary time. So I land quickly and safe with my heart racing This is my first wkm, what am I missing? Gains are default at 100 across the board, Thanks for any help you guys can give me, Jason
