"Red sky by night, sailors delight!" Nice pics! I'm still tinkering with my Iris+ machines. Going to mount a GPS on a mast, as I'm in an area with lots of trees and vegetation. I would like to be sure I have a good GPS signal, before I dare to do any "auto" flights. And I'm still learning, (trying to), all the tweaks available with the Pixhawk system. I hope 3DR gets all their eggs in the same basket, as there seems to be some confusion, at present. New product release, and a move across the world at the same time ???
