  1. I was talking to a pilot the other day who had a crash where he was flying in Arizona, it was 96 out (stated ambient operating temp of the Phantom 4 Pro is 104). And the Lipo expanded and ejected. He thinks it must have been due to the temps. Seems like not all LiPo batteries, even from the same manufacturer are identical so maybe it was a faulty battery? Has anyone else run into this. I'm scared now to fly my drone in anything like above 90 degrees F. I know you aren't supposed to store lipos in the fridge as you can get condensation inside but I'm wondering if anyone else that flies in hot climates briefly chills there batteries in a cooler or something while on site or has other practices specific to the hot climate such as allowing a cool down period for the drone between battery changes?
  2. Anyone attended BOTH Interdrone and ExpoUAV Americas in Las Vegas before? If so, can you comment on how they differ? More attendees from certain industries in one over the other? Different level of focus (on average) in the break out sessions? Different approach/organization/flavor yada yada.
  3. We all ocassionally see these news stories about Drone Delivery to people's homes. It all started how many years ago with Amazon? Then I saw one about Dominos deliverying pizza in India. Now this one: https://uavcoach.com/uber-drone-delivery I have some strong opinions on this. I'm curious when people think we will start seeing Drone Package or Fast Food Delivery begin actually happening with delivery to real homes in a city in the United States?
  4. Testing a Parrot Sequoia and the RGB photos are terrible. It's not a drone speed issue as I tried even on the lowest speed setting in Pix4D Capture. When you have motion blur issues it's consistent throughout the image. This is the strangest thing I've ever seen in that it has what looks like bands of blurriness as some bands of areas like more detailed than others. Trying to determine if I have a bad RGB camera sensor. The other camera the images are consistent detail throughout the frame. This is 4 inch/pixel GSD (135 feet AGL) https://i.imgur.com/dP7bDIM.jpg I know 4 in/pixel is not very high resolution but the images look very abnormal. Again, this is flying at slowest speed setting. There was absolutely no difference in the image between the fastest and slowest setting.
  5. With maybe the exception I would imagine of the military (bases), do any other Federal Agencies (DHS for example) have authority to regulate (impose rules/laws) on where UAVs can and cannot be flown? Or do all Federal Agencies need to exert their "will" so to speak through the FAA? Note I am talking FEDERAL only. NOT state, county, or local cities.
  6. So I was curious about Dronebase and a search here brings up this thread so I'll rekindle it a bit. I noticed on their site they state back in October they stopped doing Gerry images missions. Was anyone or does anyone know anyone that was getting a significant number of Getty images missions from Dronebase prior? Did the end of the relationship cause a big decrease in possible jobs? They also state on their website they pay $70 for "Insurance Jobs" I take that to be roof inspections. It seems from the couple of really big Hurricanes in the South/Southeast over the last year or two, there was a flood of requests for drone services for roof inspections. I'm guessing Dronebase and a few other companies possibly capitalized on this. But the demand is highly variable based on storms (not that there's no demand at all when there hasn't been a storm.) But talking to a few pilots I got the sense that a bunch of pilots experienced the surge but it just exaggerated pilot expectations for future work of this type. Has Dronebase's Insurance Jobs been growing quick, steady, stagnated, or been all over the map because they are mostly tied to storm activity? Not having used the app, what's this about the payout score in the context of someone saying "likelihood of payout" Dronebase isn't actually asking pilots to run a mission that you might not get paid for (other than training missions) are they? I do know one thing Droners in general is much much more visible on the Internet than Dronebase. We all know how few and far between Droners jobs are since they've essentially created a "race to the bottom" market over there at Droners with a high Supply to Demand ratio. If Dronebase is much less visible than Droners on the Internet, they probably have a fraction of the jobs, especially after the merger with Precisionhawk and Airvid and if they have quite a few pilots, then any reports in the forums from pilots that have gotten a significant number of jobs from them may just be the exception to reality with Dronebase in my educated guess. The only exception would be if they've done "offline networking" to forge a lot of relationships with big national companies (like Getty - now a defunct relationship, and a few insurance companies probably.) The problem with that is as time goes by, the large Fortune 1000 national companies are going to be the companies most likely to take their drone operations in house eventually, if they already haven't. Also the fact that Dronebase wasn't bought out by Precisionhawk is most likely a bad sign. I doubt they turned away a sales offer thinking they could come out on top and beat the combination of Precisionhawk/Droners/Airvid. So I would assume they never got an offer because their job volume was too low and/or inconsistent. Anyone have any insight on the current status of Dronebase?
  7. Looks like enough of the FlyGuys pilots are getting tired of paying them a monthly fee for little to no jobs. I wonder how many paid a year's worth of fees to help pay for FlyGuys' online advertising and DroneDeploy/Pix4D business subscription, and didn't make their money back? Is their a no-job refund policy? This just in from the FlyGuys Pilot Newsletter... 2018 Pilot Beta Programs Based on pilot feedback, drone business support tools are still of high interest, yet paid programs are not useful before a certain mission traction is reached. So the early 2018 FlyGuys pilot programs, Standard and Plus, will be closing on December 31, 2018
  8. Well, now I want to edit my original question.... Anyone get authorization in a LAANC 0 altitude grid in CLASS B or CLASS C airspace? No luck here for 75ft about a mile from runway but not in the flight path.
  9. I want to take some Commercial Real Estate Photos at 75ft in a 0 altitude facility map section. It's about 1.2 miles from an airport runway (class C airspace) but it's not in the approach or takeoff path. Now we all know, common sense tells us, if an airplane is flying below 100 feet where there are 8 story buildings, especially if it's not in the landing or takeoff path, then you have much bigger problems than a drone. Is it impossible to get auth? Does anyone really know?
  10. Is anyone aware of tools/workflow to help classify surface features (trees, shrubs, bare ground) using RGB or Multispectral imagery (as opposed to LIDAR) as an alternative to importing an orthomosaic into a GIS program and manually identifying and mapping the surface features?
  11. Wondering what people recommend as the best free or very low cost practice tests that have the most current array of questions?
  12. Oh I see. You use a high enough resolution sensor so that you can make one pass, capturing multiple lines and then zoom in when inspecting the image to get the detail you need on the lines, insulators, and other components. Do you still use a camera with optical zoom during flight to get extreme detail on certain areas, or is the sensor resolution high enough that you can forego the necessity to use optical zoom during flight? Do you typically run an IR and RGB camera at the same time or is IR not required in many situations? It would seem to me like the IR information would be more valuable for detecting issues?
  13. A common voltage is 345,000. Let's assume that.
  14. What's a typical mission plan for power line inspections? I've read distance recommendations from 20ft to 100ft. It seems to me at 20ft, unless you are using course lock or similar, you could have issues keeping the line in the frame depending on how fast you are flying. Are most companies looking for thermal videography of the entire transmission line for a distance to identify obvious problem points and then more close visual inspection of insulators near the towers using a zoom camera? I really can't see how visual RGB images would be that useful as an insulator in the early stages of failure could look fairly normal from afar. Breaks or issues in the actual line would also not be very visible unless you could get very close-up images. Running a closeup inspection of a line for several miles would just be extremely cumbersome.
  15. Looking at a potential application where I need to measure the settlement of land over time. The land is not covered by much vegetation so photogrammetry is an option. However obviously I need at least one ground control point outside of the subject area that is on stable land (such as a survey monument). I'm looking for relative elevation accuracy within 3 inches which can be achieved by flying pretty low (Say 0.5 inch/pixel GSD). It would seem to me, with a ground control point on can "anchor" each subsequent survey to, there's no practical significant benefit to using RTK or Lidar?
