I have this and have since I bought the 1v2 I can be out no more than 1200' and when it hovering at 250' or 400' no matter the altitude it looses signal when rotated back towards me ? Now I been told the antenna's are in all four legs but that's not how it acts ! And the most range I can get and keep signal it 1590'to 1657' is the furthest I can fly out from me and this is in the middle of no where on a farm flat as can be so I bought the little booster that slides over the existing antenna and it stopped the lag in video but no help at all with distance ? Really disappointed in this but otherwise a wonderful bird ! Been to the shop a few times and they want to sell you a four hundred dollars for a big awarkward extender but I'm reluctant because it won't go in the case with my drone
