We're beginning a project that will require offboard software control of a Pixhawk-equipped quad (we're using an Iris+).  We'll have to send pitch, roll, thrust and yaw values rather than waypoints.  We plan to use pymavlink and Dronekit.  In pymavlink I see a couple of commands that seem like they would do the job: rc_channels_override and manual_control_send.  Since both exist, I'm sure that they serve somewhat different purposes.  Is one better suited than the other for what we need to do?  Or perhaps there's another command I haven't yet discovered that's better than either of these?  Thanks for any insights and/or tips.
