  1. 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.
  2. I use very thin adhesive tape on the top surface of the blades, with excellent results.
  3. 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.
  4. 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 controls trying to keep it exactly in the same vertical position. When you will be capable of doing so, rise the height to 150 mm (6") and continue practising and so on. Then, re-do the same routines with the front of the drone FACING YOU, learning inversion. BE SURE TO BE CAPABLE OF THOROUGLY CONTROLLING THE DRONE BEFORE DISCONNECTING IT FROM THE STRING AND TRYING TO FLY IT IN AN OPEN AREA, AWAY FROM PEOPLE, VEHICLES AND BUILDINGS.
  5. 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.
  6. 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
  7. 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.
  8. 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

    PLACES TO FLY

    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 civil aviation authority (CASA) about these matters. I hope the effort will lead to safe drone flying. Cheers from Bruno
  10. 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
  11. 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 DANGEROUS in the hands of an inexperienced one. If any of your students were to be harmed by it, you would be in a heap of legal troubles, beside feeling personally guilty for ever. 3) As I have ALREADY REPEATED MANY A TIME, CHOOSE A HEXACOPTER OR OCTOCOPTER, because they are REDUNDANT. A quadcopter IS NOT: if it looses a motor or a controller (ESC) it will be TOTALLY UNCONTROLLABLE!!!! 4) Please take the time to read several of my posts about leaning to fly a multirotor. It will help you. CHECK ALL MY ATTACHMENTS AS WELL: you will see quite a few of my multirotors, which I have designed, built and regularly flown and fly for videography. 5) Your possible best option with less than $200 to spend is this: http://www.ebay.com/itm/MJX-X601H-6-axis-Gyro-RC-Hexacopter-Drone-FPV-With-WIFI-Camera-LIVE-Video-Gyro-/121970897347?var=&hash=item1c660831c3:m:m5YY4uWuD9SgsFqms0mJAdA It is easy to fly and fairly safe, because of the propeller protectors. It is small enough to be flown indoor and big enough to carry the extra weight you require. The camera is fine and it can be connected by WI-FI to any mobile phone, to have FPV (first person view). I do not think you can have a better option for your proposed enterprise. I am not advertising any seller but this one is better rated than others. Please feel free to contact me if you need help: my email address is uncle72@optusnet.com.au My Skype handle is "sigrana". I live in Melbourne, Australia. Here are some of my videos, from the earliest one to the latest one: you will notice the progressive improvements.

  12. 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-Camera-Gift-Red-/291946742908?hash=item43f961c47c:g:GDQAAOSw5cNYL0A4 This model is ideal for beginners and easy to control. MAKE SURE TO PURCHASE AN EXTRA TWO OR THREE BATTERIES WITH IT, so that you will be able to have a few flights at the time. I am not advertising any seller, but this seller has a 100% record. Very few do. Start, as usual, indoor, in an empty gymnasium or similar building, WITH THE BACK OF THE DRONE TOWARDS YOU. Learn to hover it at a few inches from the ground, gently taking off and landing it many a time, until you can do this well. Then rise it at about three feet form the surface and very gently make it go forward, backward and sideways (bank) again many times. Land it and with the next flights start to use the yaw. When you will feel confident, take off WITH THE DRONE FRONT FACING YOU and...learn to reverse your instincts...! If you need any help, let me know. YOU CAN CHECK MY OTHER POSTS TO SEE MY OWN DRONES, which I designed built and fly for videography. All the best! Cheers from Bruno
  13. You are welcome. Please have a look at my posts and you will find several answers and advice I gave to beginners. Cheers from Bruno
  14. SOUND ON!. https://www.youtube.com/watch?v=FNU_WaCSV8A My latest video taken with my older hexacopter (the FC on the newest had a tantrum...!!! on that day. It is fixed now). The gimbal worked very well, even if at 60-70 metres from the ground the apparently very light wind became something else..... the views are beautiful and the wines produced by the owner, a very good friend of mine, are excellent. Enjoy! I used as a sound track one of my compositions : "Pink grapes"( from my CD "Impressions", Portugal, 1998). It seems to fit as a glove, for some reason. Cheers from Bruno
