  1. There are a number of drones on the market, but they all are too small for your requirement, have a fairly limited flying time (if the manufacturer declares a max. flying time of 15 minutes, cut that by three) and often not much reliability. They are designed to carry their own weight (generally 250-400 gr) plus a maximum of 100 gr camera, unless you wish to spend quite a lot. The other thing is that building your own (not buying a kit) will help you to understand how the multirotiors work and it will be very satisfactyory. I still suggest that you try and build. I will be happy to help y
  2. As a designer and constructor of mukltirotor models, I will be happy to give you a few useful tips. 1) I warmly suggest to use a hexacopter or octocopter configuration. Quadcopters are not redundant (e.g. if one of the motors stops, the model becomes uncontrollable and crashes). 2) Use good quality motors. I would recomment the EMAX CF2822 1200kv version, with three blade 8" x 4.5" propellers. This motor is very reliable and efficient while fairly inexpensive. I am adding a couple of useful links from good sellers: https://www.ebay.com/itm/1pc-CF2822-1200KV-Outrunner-Brushless
  3. I have designed and built several successful drones and I am attaching a few photos of the last one. I warmly suggest for you to avoid quadcopters, because they are not redundant at all (if one engine ore ESC mulfuntions, the drone will tunble out of control, which is extremely dangerous). My advice is to design and built an hexacopter or octocopter, using motors like the EMAX CF2822. You can see my latest video, taken with my hexacopter carrying my Xiaomi 4k camera: SOUND ON! If you need more advice, you are welcome to contact me at my email address: uncle72@optusnet.com.
  4. You can doubt as much as you like, but I have used my way for the past 22 years and it works brilliantly. It is also very easy to apply and it does not diminuish the performance of the propeller.
  5. I use very thin adhesive tape on the top surface of the blades, with excellent results.
  6. If I were travelling I would forget about quadcopter and choose a small hexacopter with camera. Hexacopters have redundancy, while quadcopters do not. If one engine or a channe of the flight controller fails in a quadcopter, one loses the craft and quite certainly damages the camera and the FPV on board.
  7. Gerald, when you will receive the chord back, charge the battery, then connect a 400 mm (16") string to the centre-bottom of your charged drone (power off, of course), connect the other end of the string to a screw and screw it into the centre of a wooden table or board, at least 1200 x 1200 mm(4' x 4') wide and long. Carefully position the drone (FRONT LOOKING AWAY FROM YOU) with is centre-bottom on the screw, STEP AWAY FROM THE TABLE. Radio on, power on and VERY SLOWLY and carefully start to open the throttle 'till the drone will float at about 100 mm (4") from the table. Carefully work the
  8. You will need something bigger and stronger than that. The drones you mentioned do not really have a decent weather capability and enough autonomy to be used for the job. QUADCOPTERS HAVE TO BE AVOIDED BECAUSE THEY ARE NOT REDUNDANT. You will definitely need a ground controllable camera with video transmission and something of the type of hexacopter or octocopter, as the Asctec Trinity ( see http://www.asctec.de/en/asctec-trinity/) with video goggles.
  9. You are welcome, Chuck. I do not wish at all to throw water on your fire, but if you started from scratch, the cost of building one would be far higher than the USD 200,000 which is the price of the Ehang184. I could as well design one for you, but the constructing cost and the cost of materials would be high. Cheers from Bruno
  10. I believe the real point here is to realise that millions of dollars of public money are used to build top equipment which CAN BE USED BY ABSOLUTE MORONS TO PROVE NOTHING!!! This is completely ridiculous. It reminds me of the famous Lapalisse, the "philosopher" who was emphasising the obvious at all times.
  11. I have just found this link and it represents what we used to call, in high school, "Divertimento innocuo per bambini scemi" (= innocuous play for idiotic children). This is more silly than innocuous, though. The only contrusctive result was the behaviour of the li-po battery pack, which survived because of its insulation. http://www.digitaltrends.com/cool-tech/lightning-drone-experiment-university-of-manchester/ Cheers from Bruno
  12. You are welcome. Basic international rules: 1) 150 meters (500 ft.) from buildings. 2) 120 metres (400 ft) maximum altitude 3) NO FLYING OUT OF SITE (binoculars NOT INCLUDED). 4) 30 metres (100 ft) from any person or animal. 5) NO FLYING ABOVE TRAFFIC. 6) NO FLYING WITHIN 5,500 METRES (3.4 miles) FROM AN AIRPORT OR AIRFIED. I am, as you are, a passionate videographers and I follow the rules. I live in Melbourne, Australia and we had so many accidents created by absolute morons that you woyuld not imagine. I am at present collaborating with and advising the ci
  13. Hello, Laylow. If you wish to design and build your own drones, you may have a look at all of my attachments in previous messages. I like to build drones for videography. If you need any help, please let me know. I will be glad to advise you. Cheers from Bruno
  14. Well, Tom, safety first: 1) If you do not yet know how to fly a drone, YOU MUST LEARN BEFORE EVEN STARTING A SIMILAR PROJECT, left alone for the students to fly it. Multicopters are not as easy to fly as a standard RC model. 2) Indoor will be fine, but...WHERE? You will need a reasonably large indoor building e.g. a completely EMPTY gymnasium or church hall or similar. EMPTY mean exactly so. While learning to fly a drone, NOBODY BUT THE APPRENTICE PILOT and an eventual instructor MUST BE THERE. These toys, while perfectly safe in the hands of an experience pilot, CAN BE UNBELIEVABLY
  15. You are both welcome. As I always recommend to beginners, start with a small hexacopter (6 motors drone). The reason is that while qudcopters are NOT REDUNDANT (if you loose a motor or an ESC the craft will be totally uncontrollable and crash with ...consequencies!!!) HEXACOPTER OR OCTOCOPTER CAN LOOSE UP TO TWO MOTORS OR ESCS AND STILL BE REASONABLY CONTROLLABLE AND POSSIBLE TO LAND. You can get a very good, strong, lillte hexacopter, complete with transmitter and camera, for a very low price: http://www.ebay.com/itm/W609-10-4-5CH-2-4G-Remote-Control-RC-Gyro-RTF-Hexacopter-w-HD-Ca
