Lost my Iris+ when I took it out for a mission today. Put it on auto to do it's mission and set the drone so that it would RTL if the battery voltage goes below 10.5 V. Needless to say it did not return. I am using APMplanner 2.0 to do the mission planning stuff. 

Any advice or help would be appreciated.

    • start walking in the direction the unit flew off to.

    • Tried that. Still did not get any signal. It went from beeping for when iris loses signal to beeping showing a 10.4V reading. Can't go out any more, because it is too late, but going to check in the morning.
