  1. If this drone is PNP (plug and play) it will not come with a receiver and transmitter/controller. If its a BNF (Bind and fly) then it comes with a receiver but not the transmitter/controller. Which one do you have as it will determine what radio you need ?. Also if its BNF what model receiver does it have ?. Personally I prefer FrSky radio products that run OpenTX software and I've noticed that a lot of FPV racers use their controllers. You will also need to add goggles or a monitor to view the video but you could do without one of those to get started.
  2. Looks like they are available to order for $819 or $929 https://store.dji.com/product/dji-digital-fpv-system
  3. Looks like the "HereLink" does have some sort of encryption although no real details https://discuss.cubepilot.org/t/support-for-encryption/1370
  4. I got introduced to drones back in 2013/14 after backing this kickstarter. I opted to purchase the DIY kit and a few months later received a box of cheap parts without instructions and little support from the creator but eventually after a lot of googling and help from some other backers I did get it to fly although not quite as well as in the video. The positive outcome from it was I was hooked and since then have built several drones. With the help from DPGS I obtained my Part 107 back in September of 2016 and although I have yet to build a drone business I am an avid follower of t
  5. I now understand why you didn't provide this as your quad uses DShot ESCs and those fields don't show up. Instead the field "motor idle throttle value" appears.
  6. It looks like ArduCopter has introduced some limited object avoidance code but I have not used it. http://ardupilot.org/dev/docs/code-overview-object-avoidance.html Of course you would need more sensors if you wanted all round detection. For example I see that TeraBee make a multi-directional array using their Evo sensors. https://www.terabee.com/shop/lidar-tof-multi-directional-arrays/teraranger-tower-evo/
  7. If the Pixhawk is being powered by the power module I don't see any reason to have a capacitor. Now the Pixhawk can also be powered by the servo rail which could be used as backup power if the power module voltage drops too low. Mainly though the recommendation is to add a zener diode to this rail to limit the voltage although I've seen some also recommend a capacitor but according to the Ardupilot wiki the diode is all that's needed. http://ardupilot.org/copter/docs/common-powering-the-pixhawk.html
  8. Its normal for the motors not to spin-up after arming and increasing the throttle when the drone is connected to the BetaFlight Configurator. Its a safety precaution but you can spin them up with the motor test providing you enable the "I understand the risk....". In BF Configurator select "receiver" from the left menu and check the min and max values by moving the throttle. For example on my quad (not the same as yours) the minim throttle value is 988 and the max is 2012. Also in the "configuration" under ESC/Motor Features what is the minimum throttle value ?. On my quad its set to 1
  9. I am beta testing the new FAA's B4FLY mobile app and assuming I have the correct location of the park here is a screen shot from my iPhone. I would check again by calling the state park administration and don't go by just one park employee's word.
  10. @Dawson Fernandes @Av8Chuck I don't know how this compares with the "HereLink" but they look very similar. The HereLink also has an integrated Android tablet and runs QGroundControl. Its available from various distributors including these guys. https://www.getfpv.com/herelink-2-4ghz-long-range-hd-video-transmission-system.html It was designed by the same folks that developed the Pixhawk 2.1 "Cube" which is now called the "CubePilot" Bobby Watts, the founder of Watts Innovations recently tested this controller.
  11. Looks like the US Department of the Interior has validated this DJI solution https://unmanned-aerial.com/interior-department-approves-dji-government-edition
  12. Yes, you need to have an external BEC or ESC with a built in BEC in one of the output ports to provide enough power for the servos. If I recall you can do this but since you are simply passing the signal from the receiver to the AUX output you may as well just connect the receiver directly to the servo. For example in the case of retractable landing gear I wanted to have the flight controller deploy it when performing a RTH but at the same time I wanted to have a switch on my Taranis also be able to deploy it manually.
  13. This is a good place to start http://ardupilot.org/copter/docs/common-servo.html So firstly there are 6 aux outputs that output 2 types of signaling, either "servo" or relay. Servo would be used when the device that you want to control uses PWM input and relay when it requires just 0/3.3 volt input. You can change this combination of servo/relay allocation of those 6 outputs with the parameter BRD_PWM_COUNT. Also consider these parms SERVOx_FUNCTION where x is 9 to 14 for AUX 1 to 6 respectively. This parameter will determine what function is performed. CHx_OPT where x is
  14. I know that the its possible as I had configured retractable landing gear on a HexCopter. Initially I just had the landing gear control connected directly to a channel on the X8R receiver and so manually controlled by a switch on the X9D but later connected it to the first AUX port of the Pixhawk so that the landing gear would automatically deploy on a RTH. I'll check my notes on how I did that.
  15. Looks like these guys have done a great job of using drones in eduction in Russia. Warning the video is long but if you are interested in using drones in education worth the time to watch. P.S I pulled this out of another thread that I created in the DIY category.
  16. After watching all the sessions this has to be my favorite. Its a Russian company that focuses on using drones in education and it looks like that they have done a fantastic job. Warning this video is very long but if you are interested in using drones in education its really worth the time.
  17. Yes, I believe that was back when 3DR were still involved with DIY. My understanding is that the licensing is also no longer same. Ardupilot uses the GPL licensing and PX4 uses BSD licensing. The difference is that with GPL any contribution to the code has to be shared whereas with the BSD version that PX4 is using it does not and its why its favored by companies like Yuneec. He recently founded https://auterion.com which like RedHat is for enterprise Linux they provide enterprise PX4 software. They received $10M in seed funding last year.
  18. Actually I have more experience with the Ardupilot flight stack than PX4 but thought it would be interesting to watch them and so yes I have watched quite a few and I am currently watching the one on UAVCAN.
  19. I like to use this open source flight control stack http://ardupilot.org It provides both manual and autonomous flight modes. You can even setup a development/test enviroment on a computer without actually building a drone. Its a good way to learn and understand the flight control software and ground control station. Let me know if this is what you are looking for and I can help your further.
  20. The open source flight control stack PX4 recently held a developer summit in Zurich and have published the sessions on their youtube channel https://www.youtube.com/user/PX4Autopilot
  21. Ok...... https://www.commercialdroneprofessional.com/dji-launches-most-secure-drone-solution-to-date-for-use-in-high-security-situations/
  22. I think that I already have one although not 70mm.
  23. Also this guy is really good with FPV troubleshooting.
  24. That's too bad. I don't FPV race so can't recommend a drone although I do have a Tiny Whoop style drone to fly around the house. I mainly like to build larger autonomous drones, both multi-rotor and fixed wing. You may want to check out Oscar's site for recommendations. Also I noticed that he has these tips for troubleshooting arming issues. https://oscarliang.com/quad-arming-issue-fix/
