Hi All I am interested in exploring the feasibility of monitoring wild game activity in African reserves with rc surveillance. This would mean prolonged flying times and the ability to fly far out of line-of-sight and leads to many questions I can’t answer. Which is the best flying platform? What is its maximum flying time and range? How bad do weather conditions have to be before they are grounded? What are the problems inherent in night flying? To what extent can a vehicle fly pre determined circuits by GPS and auto pilot? If one spots a situation that needs attention, will it send back coordinates so that a ground team can be dispatched? There must be myriad considerations that I don’t yet even understand. Is there anyone out there with any ideas?
