Just arrived Friday afternoon direct from DJI website 7 days ago - superb but was raining to much to fly it so maybe over this weekend we will get it airbourne!! - Plus the GO app was updated the same day so you can now select the matching model.... So we will report back with what its like.
No the "Video-Wif" Antenna is internal as you can see it when you remove the lipo inside on the side - range is superb we had a "WALK" around a nearby substantial brick building because it was raining heavily and didnt break up plus no noticeable "lag" - We did it twice just to make sure - Perfect picture both times - very impressed! -
