DJI has done it again. I was just upgrading the firmware, and Naza Assistant software , and GPS is no longer a choice, ATTI now replaces it. I'm sure it's a typo, as when I flew afterwards it was in GPS mode, but you would think they would try to be a little more PROFESSIONAL. It's not very confidence inspiring when you are programming something that has the ability to fly away, when they make such basic stupid mistakes. Perhaps Colin Guinn should either okay it himself, or have some other ENGLISH speaking person very familiar with the product do so.
