Attached is the video of my Arducopter Quad 1st Waypoint Trial. In the Flight Planner I set 5m Altitude for overal points and only checked the Hold Default Alt box. My Quad went up n down from one waypoint to another, didnt complete the point and went different way and at last went down slowly to the ground. It also overshoot whenever i engaged Alt Hold. Firmware 2.0.53, MisionPlanner 1.0.99.Appreciate your help.TQ

Watch from 0:16secs to1:40min
