  1. I don’t understand your question? You answered this topic, right. Do that again.
  2. Spent the day at the 2021 Overland Expo in Loveland Colorado. Lots of cool toys to play with! It was the first time I had attended, just walked, talked and shot video. No narrative just for fun. There's more to life than drones...
  3. Hi Mike, welcome to the forum. I don’t fully understand the use of the term “streaming?” If your asking how you can stream video from a camera on a drone so that you can monitor what the camera is doing, that’s pretty straight forward. Or are you asking about streaming directly to the web? If your hoping to learn about UAVs from a developers perspective check out: https://ardupilot.org/index.php
  4. Failsafe isn’t necessarily there to save the drone, it’s more about the drone going out of control and not damaging or hurting others. if your drone looses control inputs, telemetry communications, or GPS it can be programmed to hover in place, land or return to launch. Most DJI drones can be setup this way. Other OpenSource based flight controllers can provide many more options.
  5. There are several things that effect range. It’s illegal to fly beyond visual line of sight. Transmitters are line of sight so any occlusion will effect range, trees buildings, hills etc.. Flying in dense WiFi areas Flying close to high energy sources like transmission and cell towers. Depending on the type f drone you have there is a good chance that if you fly beyond control you’ll lose your drone. That mostly depends on how the failsafe is configured.

    Hi Tim, welcome to the forum. This is a GPS issue not a drone issue. GPS is line of sight and DTLA is pretty dense and can cause GPS to be ineffective. The issue is what does the drone do when that happens? If your dumb thumbing it then not having GPS should not effect how the drone flies, you’ll still have alt-hold but it will drift laterally. If you need to repeat a flight path then you’ll need an Internal Navigation System. Keep in mind that depending on the quality of the INS it will drift. INS ranges in price from several hundred to $13K for an Applanix — https://www.applanix.com/products/dg-uavs.htm Really depends on how not having GPS effects your mission. We’ve shot DTLA quite a bit.
  7. Welcome to the forum. I don’t know where that is but I’d like to be there..
  8. There are a lot of variables you need to take into consideration for owning and flying a drone. Do you know the speed limit on the 101 or the 405? Obviously its 65 but no one drives 65 in the LA area. Depending on time of day they drive 80 or 30. So are all those drivers breaking the law? Technically yes but most go with the flow of traffic which is rarely 65. My point is that if your a person that drives 65 because that's the law you might have a difficult time finding places to fly in LA. If you use common sense as a guide and can "go with the flow" LA is a great place to fly drones. Why do you want to fly there? Its a nice park but doesn't look any more interesting than lots of other places to fly. I stay away from parks as much as possible, too many liberal idiots in parks that think its their job to tell you what you can and can't do. Its easier to just stay away from them. It also depends on what your hoping to accomplish with flying a drone. If you want to do aerial photography for YouTube videos etc, then a small MAVIC2Pro is a good choice. Small enough to launch from just about anywhere, doesn't attract much attention when its flying and if you are careful how you fly it not likely to seriously injure anyone if it crashes. Phantoms have a bad rap, they're a little bigger, white, louder and stand out more without giving you any improvement in image quality. If your hoping to do more professional aerial the next size up would be an Inspire2. DJI is sunsetting this product line so spares parts, batteries and accessories will be harder to find and more expensive. Plus they are not quiet and much more noticeable flying around. Anytime you fly anything there's some risk involved. The challenge is that when flying a UAV remotely you are extending that risk to other people without them accepting the risk. When your driving everyone else who's driving on the same road share the risk. I regularly fly over a state park, is it legal - no, but that doesn't make me unsafe. The only Park Ranger to ever say anything to me was flying a MAVIC shooting aerial of the park. Fortunately the other Rangers recognized the hypocrisy of his actions and after pointing out how much better my footage looked than his they just told me to pick up my toy and go home. Common sense and being respectful of the proximity of other people goes a long way to enjoying flying in LA. I've flown downtown at sunrise on a Sunday, there was no one there to complain.
  9. Nope, I disagree. Its beautiful landscape to be sure, but your reveals, the use of natural sounds, clouds as wipes, timelapse, color balance and even your choice of music is excellent. You provide much more than an aerial perspective you really capture the essence of what that place is like. I do have some suggestions, add more ground footage. You come around the corner of the mountain to reveal a building, it would be great if you had a low angle shot of the building looking back on the building to reveal where the establishing shot was taken. There's also two smaller lakes off in the distance in several of the shots, it makes me really want to see those two lakes closeup. Finally you have a bad frame around 2:21 when you cut from the timelapse. This is a very nice video. Keep up the great work and thanks for sharing.
  10. There’s some pretty good aerial, if that was what you were hoping for then you accomplished that. However, the fact that you wrote such a detailed explanation about this place leads me to believe there’s a story that you wanted to tell and in that regard the video did not accomplish that. So it really depends on what you hoped to accomplish by posting the video. My recommendation is that you shoot for the narrative you added in your description and add that to the video. Television is a closeup medium, aerial is great for establishing shots, you can add creative reveals and orbits but a little of that goes a long way. If you had flown low and close to the mansion, or low across the lake to the door to “walk” the viewer into the mansion, shot a lot of stills and video on the ground. Closeups, even extreme closeups of the architectural detail, widows, doors, and grounds you could add your narrative as voice over. You’d need about 300 shots and should try to keep it under three minutes. Here’s an example of one of my videos. I wanted to show life prior to COVID-19 and present it in a frenetic way so the video would move along. It’s missing a narrative but it’s shot and edited in such a way that the viewer gets a sense of what’s going on. I’d like to add voiceover but that’s a lot of work and I’m lazy.
  11. Welcome to the forum. I think lots of people do what your suggesting. The challenge is integrating the use of the drone and the resulting footage into your work. I like to use the footage in a way that the viewer might not even be aware that it’s aerial footage. It certainly provides a unique perspective but it makes the audience think how was that shot accomplished? Far too many people are more concerned with showing off their flying skills than they are about creating great photography or cinematography. So when you view a lot of aerial YouTube videos they pretty much all start to look the same. It all becomes pretty mediocre. So I think aerial works better if the “aerial” aspect of the shot becomes transparent and the perspective speaks for itself. There’s more aerial in this video than you might think. I like revealing points of interest, shoot from the shore of a lake but then reverse the shot and shoot from the lake to the shore. It just looks like a shot from a tripod on the water, no real hint that its aerial other than it might make the viewer wonder how you got the shot. We just purchased a travel trailer that I hope to use as a mobile studio to work from. Good luck and don’t hesitate to share your work and ask for help.
  12. What are you trying to invert from? There’s no free lunch. The flying time you get is directly proportional to the energy you put in. The only thing you can do is changes the energy source, use larger batteries, use higher voltages (ohms law), lift smaller payloads.
  13. We'll have to do it remotely, I’m in California. Forming a committee is easy, it’s the voting block that you need to represent. For a PAC or Trade Association to be effective they’d need about 1M members.
  14. @Adam Munson welcome to the forum. Great first post. I’ve suggested these sorts of political action committees and a trade organization but it mostly falls on deaf ears. I guess people are busy and maybe they feel powerless to take on prerogatives of the FAA. As tax payers all we need are numbers. With 635K members AOPA was able to influence all manner of legislation. Unfortunately I doubt we can muster more than 10.. people just aren’t interested in helping themselves. They don’t think it’s necessary until it’s too late.
  15. Hi Richard and welcome to the forum. There's was the FAA require for you to fly commercially and then there are the requirements of a successful drone program (even if its only one drone). Chase has provided good information for getting the legal side started but you should also consider what your requirements might be to make a happy boss. What problem are you trying to solve using a drone? Its more of a program issue than a drone issue.
  16. People have different aversions to risk so there's no one right answer to your question. Regardless of 4S, 6S or 12S we never reduce the energy to less than 20%. Depending on how well you maintain your batteries, LiPos build up internal resistance with every charge cycle. So we keep at least 20% as a margin of safety. If we're flying something expensive and heavy we'll up the required amount of remaining energy as high as 40% Sorry I just noticed that this is posted in the FPV racing thread. The same rule of thumb applies about not taking the voltage to zero but people flying FPV often go to 10% remaining voltage. Internal resistance still goes up with the number of charge cycles so if you go below 10% there's a higher risk of damaging the battery.
  17. Hi Vern, welcome to the forum. It was interesting reading about your experience. I think what UAV Coach does to help people get their Part 107 is essential. I'm glad to hear that the program worked so well for you. Thanks for sharing. I think from your description your first foray into the business of drones was more on point than you might think. You were just about three or four years too early. When you consider what problems drones were solving at the time, people who approached the solution from the perspective that the "drone" is not the solution, its an enabling part of the solution were constantly ridiculed by people who wanted to argue that their white drone was better than the orange drones. The real issue confronting industry has been the transformation from analog to digital engineering. Drones can certainly play an important role in that transition but that transformation has way more to do with role 3D engineering, remote inspections texture mapped onto as-built models combined to create the Digital-Twin. If you stop to think about it when people use a Skydio to create a reality model with a low quality camera with a tiny plastic lens and compare it favorably to a drone that's carrying a 64MP camera with glass lens that can resolve down to a mm from 200ft, you just have to wonder what they're smoking? That's where forums like this can be useful. Yes this is a UAV forum but its real value to people such as yourself is its a place to have discussions about the relevance of drones in the overall solution.
  18. This takes "online" education to a whole other level. We live in a world where everyone knows how to do everything but hardly anyone has actually done anything. If your in school and have an assignment to write a paper then it IS YOUR problem! Having said that, I hate censorship and as much as I dislike this type of post its not up to me to decide what others on this forum thinks about it. So I'm going to lock this thread. If others feel strongly that it should be open to debate I can unlock it. If you want to debate the merits of education and how this sort of service perverts it start a different thread.
  19. If your standing in the road and take pictures of someone sitting on there porch that is not illegal. If the person is recognizable in the shot then you'd have to get a release to use the shot commercially but its not illegal to take the picture. Again this is a federal issue that States often try to regulate. The supreme court ruled that there is no expectation of privacy from someone walking down the sidewalk taking a picture of a house. So the same rules apply for a drone. It has been argued that drones can have access to places that are not in public view, however, the SC also ruled that aerial photography from helicopters is in the public airspace therefore no illegal. Again because, in part, only the FAA can regulate the public airspace. Its not illegal to take an aerial picture from an airplane of a neighborhood, doesn't mean you have the right to publish the photo commercially. Do you see shots of crowds of people on your local news? Why is it legal for them and not for you? Its not. Most of your concerns aren't really drone related, these are issues that effect cameras' no matter where they are. I have done shoots in malls and a lot of shop owners have approached me to tell me that's illegal. I tell them to call the cops and when the cops show up they tell them its not illegal. Interestingly, you need a permit if you want a tripod to touch the floor. But that has more to do with insurance. There are people who believe in the "intent' of law and there are others who believe in the "letter" of the law. If your an "intent" type of person it makes flying a drone more enjoyable. If you believe you have to follow the "letter" of the law then flying drones might not be that interesting depending on your risk aversion.
  20. Depends on what you mean by location. There are different requirements depending on the type of airspace your located in, for example, the requirements to fly in Class D are the same in Texas as they are in California or anywhere else in the US. The only agency that can regulate airspace is the FAA. So you need to learn the NAS if you want to fly commercially. https://uavcoach.com In the first “recommendation” they correctly point to the FAA. States don’t have the authority to regulate airspace. FAA - Unmanned Aircraft Systems Information on drones from the Federal Aviation Administration. Here, you can register your drone, petition for an exemption and find federal rules and regulations. Texas Drone Regulations Created by the Texas Film Commission, a listing of both state and federal regulations to consider when flying a drone for film and TV productions In the second recommendation they tell you that the Texas Drone Regulations are created by “The Texas Film Commission.” The California Film Commission tried the same thing in CA. Didn’t work because it’s against the law for the FAA to regulate commerce which is what the film commission is trying to do. The NAS is paid for by our tax dollars, so we own it which is why the government can’t charge or restrict you from using it. They can only determine the requirements for using it. If you meet the requirements, you have a Part107 for sample and follow the FAAs rules then you can tell any state that messing with your civil liberties to pound sand.
  21. I posted an earlier version of this a while back. I keep adding memories...
  22. Id stop short of calling it the norm, but it is a necessity. Pricing is a bit of a misnomer, people compare the price of a Mavic2Pro to a UAV than carry a LiDAR (10 pound payload) and say that US manufacturers can't compete. Our smaller drones that can carry a couple of pounds more than a DJI M300 is about the same price.
  23. @TallDave, welcome to the forum. Where are you from? Here in the US any person who writes a controversial book and produces a documentary about it can garner a fair amount of notoriety. Get some Naval aviators on camera talking about their experiences, like the Bermuda Triangle and you have a best seller. Just because they make the talk show circuit doesn’t make it true nor does it mean it didn’t happen. My point is I don’t think the Navy is taking this all that seriously. Nuclear batteries were invented by RCA in the 50’s. Great science project, lots of potential applications in powering such medical devices like pace makers and hearing aides, but you don’t see them being used because they couldn’t mitigate the health risk. Betavoltaic power sources are particularly well-suited to low-power electrical applications. Even if they could make them safe to handle there’s no way they could meet power requirements of a drone. NASA does not use betavoltaic batteries, they use RTGs (Radioisotopic Thermal Generators) often referred to as nuclear batteries. They use heat to generate electricity, they’re tiny nuclear power plants. Ingenuity, the Mars coaxial helicopter is solar powered. The lander uses a MMRTG. Great out of the box thinking but these are problems that PhDs have been working on for decades. That battery regardless how it’s defined is worth a fortune and no one has figured it out in 70 years of R&D. The likely hood that a country that has a nuclear submarine would bring it into US territorial waters to launch some drones is highly unlikely. Not because the Navy would try to sink it, but because they have a great record of running into things... also, when you see the pictures the guy used for his interviews all the drones have bright lights. It’s a UAV, it doesn’t need lights to see where it’s going, lights on drones are so the operator can see it. If you were trying to collect data about the Navy wouldn’t you turn the lights off? It’s not even good photoshop.
