I believe that you and me, have already seen the videos and reports of Amazon Prime Air drones delivery package. Overwhelming, my first impression is : Amazon Prime Air Drones shipping was just a hype! I am a technician of multi-axis aircraft (same like the kind of Amazon's Drones) and Remote Control model company , analyzed from Drones and remote technical principles and simple logic , the so-called 30 minutes 's Drones delivery from Amazon is indeed nonsense : 1.The Safety The Amazon " advertising" video is an eight- axle vehicle, the diameter of more than 80cm, by visual with eight motors and rotors, if such a large object out of control , or lack of electricity , or ( may be many other reasons etc here ) , sincerely speaking, this aircraft falls from the height , or hit a pedestrian or animal in flight , the possibility is huge and the consequences could be disastrous 2 .The Precise Positioning From the video, Amazon Drones can be sent to the falt of the customer's door, perfect!But to achieve, such a precise positioning is difficult to do from a GPS technically currently , it is in a normal range of 10 meters by positioning error , then if the Drones to the roof, or the pool , or in front of the street, neighbor's house ? This make the customers to feel harvest then? 3 Delivery Range We know that such an eight- axle vehicle , it have two lithium batteries and 8 motors in power systems , itcan fly up to 15 minutes with the most efficient power system , this is a unload condition , Amazon claims to load 5 pounds , OMG! If laden five pounds , I believe it can fly up to 8 minutes , and to be flying back and forth ! The delivery range is 30km /h* 4/60 = 2km. according the Drones's speed is 30 km / h .what the concept ? The leisurely 10-minute 's walk need the Drones to toss ? 4 Cost How much such an 8-axis aircraft cost? For selling multi-axis aircraft , and I am responsible to tell you , this one aircraft cost $ 1,000 or even more! And the loss will be very large , this does not include the number of customers " catch " this craft to take home. Flight only loss lithium battery , rotor , landing gear, which will be a little unexpected loss , may the hung wind will make it unnormal landing , and the loss is $ 1000 ! Jeff Bezos has a great brain, I do not think he would doing such stupid things. 5 . The Federal Aviation Administration (FAA) Such aircraft fly overhead, and would interfere with the civil aviation system and conflicts , Has Jeff Bezos been obtain the FAA's approval ? I think this difficulty is quite large, this involved large number of Americans 's life safety . From this analysis, it is not easy to detect Amazon Prime Air is such out of touch. But ,Jeff Bezos, such smart people,how would do such a stupid thing ? In fact, Bezos is very clever , these is actually a very successful marketing tool of Amazon . The Timing is very good , just before Cyber Monday , the beginning of the Christmas shopping season , all kinds of the media have reported Amazon's delivery services in this time , Amazon has an excellent publicity, and you can feel the Amazon went in Technology the leading edge ( Drones) , also greatly shortened the delivery time ( 30 minutes ) ; brand marketing with excellent results ! I really do not believe Amazon Drones's Fudge , I only have deep appreciation for the event marketing . Let us learn a wireless remote control,Drones' knowledge, be a smart consumer ; ) HobbyWOW
