The accuracy of the flight path is stunning and a testament to the new inertial system developed by Randy and the Arducopter team. Looking at the path in Google earth, I can see cm accuracy in XY. Amazing! Also the transition between waypoints has a nice flow. The Yaw transition however was not very good. It’s quite sudden and jerky between waypoints. I am considering a patch to use acceleration and deceleration of Yaw to give a smoother feel for the GoPro camera.
