  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 you. Keep in mind as well that the total weight of your drone must be less that 1500 gr, including batteries and payload. Over that weight, you will need a remote aircraft licence. Please let me know.You can reach me directly at my email address: Cordially Bruno and links at bootm page.
  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: I have previously bought from these sellers and they deliver proper items. 3) The easiest and reliable flight controller to buy is the KK2: It is inexpensive, rugged and fairly easy to program. I never had a problem with it. 4) BUY A RELIABLE TRANSMITTER. I use the Graupner brand, but there are many. It is better to spend a few more dollars than to have something that easily fails. The transmitter will need to be have 8 channels and work in the (now usual) 2.4 GHz band. 5) REMEMBER: UNLICENCED MULTIROTORS PILOTS NEED TO BE INSTRUCTED. THERE ARE MTOW (TOTAL WEIGHT AT TAKE OFF) LIMITATIONS FOR LIGHT DRONES. DO NOT FLY NEAR BUILT-UP AREAS OR IN PUBLIC PLACES (APRKS, BEACHES ETC.). I am adding a few photos of my own hexacopters and a link to a video taken with one of them, equipped with my own anti-vibration device for the camera (SOUND ON!): BEST OF LUCK!
  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:
  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 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.
  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 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. 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 civil aviation authority (CASA) about these matters. I hope the effort will lead to safe drone flying. Cheers from Bruno
  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 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: 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 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.

  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: 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
  16. 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
  17. SOUND ON!. 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
  18. Welcome, Thomas. Your radio TX and RX will be fine. You will not need servos but you will need a flight controller and several pertinent brushless outrunner motors, with the correct ESC s and propellers. For the flight controller, I warmly suggest the KK2 1HC. You can purchase it here: It is easy to program and it comes with its own detatchable programmer, so you can even change the programming on the field. It is also very economical and reliable and it allows for almost every multirotor configurfation. As far as the motors and ESCs go, I warmly suggest for you to purchase some EMAX CF2822 with 30A SimonK ESCs. It is a failproof combination at a modest price. You can purchase this combination here: You will need a minimum of 4 motors and ESCs, BUT I SUGGEST FOR YOU TO BUY AT LEAST 6 MOTORS AND ESCs (better if 8). The reason is that quadcopters are NOT REDUNDANT. Loosing one motor or ESC will mean total uncontrtollability and crash, with consequencies which can be sometimes terrible. HEXACOPTERS AND OCTOCOPTERS ARE REDUNDANT, because if you loose one motor and/or ESC or even two, you will manage to land them. They are also more stable and controllable. I am adding a few photos of the multirotors which I designed, built and fly. You will be able to find in Youtube, under my name (Bruno De Michelis), several videos which will allow you to see my progress, starting from scratch, as you are. I will be happy to help you, if you wish. My email address is and my Skype handle is "sigrana". Feel free to contact me. Cheers from Bruno
  19. Excellent, Ed. I live in Australia. This hexacopter is also fairly tough and it will withstand a fair amount of punishment (crashes, bad landings etc.) I do not mean to say that you will be the one who crashes it but it unfortunately happens while you are learning. MAKE SURE TO START WITH THE BACK OF THE CRAFT LOOKING AT YOU. Learn to take off on the spot and slowly rise the drone to about a foot from the surface, then land it. Repeat this 'till you will be able to do it without any problems. Only then rise it to about a metre from the surface and carefully move it forward, backward and sideways. Be carefull to avoid yawing it while using the throttle control, thing that easily happens at the beginning. Next, rise the drone at a couple of metres from the surface and slowly make it yaw (turn around its vertical axis) until it will complete a full turn. AT THIS POINT IT WILL BE HELPFUL TO ATTACH A SMALL, RIGID ALUMINIUM STRIP (ABOUT 5 INCHES LONG) TO THE TOP OF THE DRONE'S FRONT (see attached photo). It will allow you to always see where the front is. You will be than ready to start to make coordinated turns, using a combination of pitch forward, bank and yaw. Once that you will have mastered a number 8 figure you will be fine. The next step will be to take off with the drone facing you and learn to mentally invert your controls (RIGHT = LEFT, FORWARD = BACKWARD, R YAW = L YAW and viceversa.) All the best and let me know how you will be going. Cheers from Bruno
  20. You are welcome. Please see my previous posts about this subject, which also contain photos of the hexacopters I designed, built and fly. There are videos on Youtube under my name (Bruno De Michelis). Before worrying about photo and video quality, YOU MUST LEARN TO FLY A DRONE! It takes quite a lot of practice and I warmlly suggest to you and everyone else to learn to MANUALLY fly it, NOT to rely on automatisms. Start with a medium size hexacopter (which is REDUNDANT), like theone in the link below: and LEARN TO MANUALLY FLY IT AND USE THE CHEAP CAMERA. When you will be able to do so without making too many mistakes, you will be ready to upgrade. Cheers from Bruno
  21. Welcome. You are mentioning the wrong options. 1) LEARN TO FLY A DRONE: really FLYING IT AND NOT RELYING ON AUTOMATISMS. They fail, at times. 2) When you will be able to fully control it and avoid crashing it, you will be understanding. Choose then a NON REDUNDANT DRONE (hexacopter or octocopter, NOT QUADCOPTER). You can purchase an inexpensive m hexacopter which it will be your bootcamp drone and LEARN TO FLY IT: BTW, I am NOT ADVERTISING< just trying to help. LEARN TO WALK BEFORE YOU RUN!!!!
  22. You are welcome! BTW, may I suggest that you start with an inexpensive and easy to fly drone (MJX X600, MJX X601H or similar, please see ) and LEARN TO WALK BEFORE RUNNING? If you start with a semi or fully automatic drone, YOU WILL NEVER BE ABLE TO FLY DRONES! And if one or more of the automatisms fails, you will have an uncontrollable obiect with running propellers. I warmly suggest to all beginners to buy HEXACOPTERS OR OCTOCOPTERS. WHY??? (My apologies about the cold showers, lol). QUADCOPTERS AND NON-REDUNDANT: if you loose one engine or ESC the craft will uncontrollably fall to the ground. On the other hand, HEXACOPTER AND OCTOCOPTERS ARE FULLY REDUNDANT: they can loose one or even two motors and /or ESCs and STILL BE CONTROLLABLE. THINK ABOUT IT! I have been designing, building and flying my own craft for videography. I am adding a few photos of them and links to videos on Youtube, in which one can see the progressive video refinements which I have achieved. At present, the wind here in Melbourne has been blasting for 3 months and it keeps doing so. I had to fly in my kitchen to test the gimbal and my vibration dampeners. If you need any other help, please let me know. Cheers from Bruno

    You ar welcome, Ian and I have to say that I FULLY SHARE YOUR POINT OF VIEW! About flying multirotors: do not try to run before you walk (as usual). Take kit easy, learn to manually take off and land the drone, fly it and control it at about 1 metre from the surface. I do not know what you purchased, but I normally advise new pilots to buy either an hexacopter or an octocopter, BECAUSE OF THEIR REDUNDANCY and better wind resistance. If a quadcopter looses a motor or an ESC, it will be uncontrollable and crash. Not so with the above mentione multirotors, which are controllable even when loosing two motors or ESCs. I design and build my own drones for videography. You can see the photos of several of them in my previous attachments to messages and some of the progressive testing videos on Youtube: If you need any other help, please let me know.
