Well....As a few have stated, going over or under wasn't an option because the Evo isn't even capable of climbing or descending terrain features like hills due to it's lack of sensor intelligence/updates. So that part was my fault...But I definitely remember there being an option to have it go around obstacles or just hover. It obviously had to have been a feature in one of the intelligent flight modes. Perhaps we saw a video/review of this option? Flight Deck video maybe? Maybe it's in part of the description for one of the flight modes/ visual sensor settings on the Explorer App? Now this is going to make me even more nuts! ?
