Went up for a night flight over the lake to show off the cool lights to the family. Very hard to steer with zero fpv visibility. Of course she decided to have a mind of her own and started rotating on its own making directional flight home almost impossible. Any idea what could have caused this? Tried another test flight a few minutes later and had it hover around 2 m for a couple minutes. Noticed about one foot sway from side to side and about 6 inches play in the altitude. Help lol scared to fly again
