Range 3 km? Seriously? I use eBee plus for several years. In an open field, the range is slightly more than 3 km, and over urban buildings it is much less. Aerial photography of the village can be done, there is no city! My eBee plus range 3 km, eBee X - 3 km, new eBee Geo - 3 km. SenseFly, where is the development?
