I have similar questions!! Hit Rad and Yaw Avg are mysteries to me right now. I've tried to fly a mission with my Hexa and found that the waypoints were obtained very "loosely" with lots of wandering about. Similarly it seems that the Hexa yawed to the heading of the next waypoint with a great deal of "uncertainty" .
Is the Hexa supposed to come onto heading when beginning to nav to next wp?? What is the effect of and/or purpose of these two params???
Really could use some help with this......
Been working on hit rad and yaw parameters for waypoints and we haven't found anything different from Tom's observations: hit rad and yaw have little to no effect on the mission.
It would been helpful to know if these parameters actually do anything!
If you want the quad to yaw a certain direction try condition_yaw or ROI (although with ROI you need to change the parameter YAW_OVR_BEHAVE to 1 in the advanced parameters list).
