I did that with my mavic and crashed because I descended too quickly with the line attached and got tangled. It will be covered under care refresh, everything is-- you could fly into a wall at top speed, it covers all pilot error iy

Jim Silly-Balls posted:This will definitely not be covered by DJI care. It’s way outside of the drones intended use. DJI's first response to my question was that lost drones are not covered, because I made the mistake of using "loss" as in the insurance usage of "loss" and they just keyworded onto it, ignored the rest of the e-mail, and said lost drones are not covered. I replied with a clarification but haven't heard back yet. If they won't cover it, this is gonna be a flat out "not doing it" since it's not for me and my neighbor certainly wouldn't want to pay $1000 to replace it. Thanks for the other advice and tips. I'm hoping he can just do it with a slingshot, but it is a pretty tall black walnut. A pole to do this would have to be like 90 feet long and simply isn't practical.

I have done similar with a slingshot and lead weight in lower trees. With some practice you can be pretty accurate. I was also able to get some paracord into a pretty high tree by attaching a lead weight to it and stuffing it into the barrel of a potato gun in front of the potato. That was also the most fun.

When I was learning to fly RC planes, I used a Walmart slingshot, 1oz fishing weight, and some braid fishing line more times than I care to relive to get stuck planes out of tall pine trees. The key for me was to keep the braid on a fishing rod/reel and just open the bail and fire. With the braid just laying on the ground it was impossible to keep it from micro-grabbing onto any blade of grass and consuming all the kinetic energy. I also did that to hang a HAM radio antenna in my backyard too, but the branch was only like 25ft up so I was done faster than it took me to go get the slingshot.

Mavic Mini 2 reviews our out, e.g. https://m.youtube.com/watch?v=01y6Rg_1owY https://www.dpreview.com/reviews/review-the-dji-mini-2-is-the-perfect-drone-for-beginners Glad I bought an already obsolete Air rather than newly obsoleted Mini lol. On the other hand it addresses the reasons I got the Air over the MK1 Mini So ugh. The only issue I've had is frequent compass calibration, and sometimes the horizon gets significantly tilted. Is this a known issue? I'm not sure if it's a software/calibration thing or a physical one. If I wiggle the gimbal when it's off, it feels like it can rub and even stick on the little rubber mounts on the sides. mobby_6kl fucked around with this message at 11:08 on Nov 5, 2020 |

Dji recommends recalibrating when you go 30 miles or more from your last flight point but I find even a couple miles will throw the sensors off and I have to recalibrate. I just recalibrate every time unless I’m flying in the same spot I did last time

Are there any good replacement propellers for the OG DJI Mini? My biggest issue is that I live in Colorado and I get high altitude messages a lot, limiting my flight to 30m above launch. Do they make any propellers that'll give better lift (I assume at the cost of noise?) I'm new to dronin' so don't really know trusted brands. Amazon has AxPower. Could I maybe use the Mini2 blades?

I googled it because I was curious why you'd be getting a software "high altitude limit" message, and it looks like that is something that DJI does when you have your drone in Payload Mode. Maybe look into that. Cause yeah, there's no reason that your drone should just stop flying at a specific altitude when it performs acceptably well just below it. Absolute ceiling is the point at which the maximum amount of lift you generate drops to exactly the weight of the vehicle, so you can no longer climb. If your drone can still take off and climb reasonably well at your elevation, you're nowhere near the ceiling. evil_bunnY posted:Thats not how flight controllers or motors work. In thinner air theres just a point at which a particular motor/propeller cant make more thrust. You can help it along with faster motors (higher KV rating) and steeper props. Faster motors will help, yes. Steeper props won't necessarily; the critical angle of attack is not affected by air density. Propeller aerodynamic theory is a bit much to get into, but in general if the air is thin and your motors are spinning at max RPM without drawing max current, you should add more blades to increase the swept area. Just increasing the camber or the angle of attack will have negative effects on your climb rate and maximum speed. Sagebrush fucked around with this message at 21:14 on Nov 5, 2020 |

There are tons of reports on the FB Mavic Air 2 group that the new firmware is causing in-flight disconnection issues. Basically the drone will randomly drop the connection and do whatever you have it set to do when it loses connection. This is a good opportunity to: 1) make sure you have your drone set to RTH when it loses signal. At least one person had it drop the signal over a tree and had their drone set to “land immediately” when the signal was lost 2) wait for the next update. Hopefully they will fix this quickly.

I mean, as long as you have it set to RTH and keep a clear flight path back home, you should be fine. I have mine set to ascend to 200 feet then return home and the few times I’ve needed to RTH it’s been fine. Also according to this it may have been stealth fixed? https://www.facebook.com/groups/1872922312982687/permalink/2809388079336101/ Beve Stuscemi fucked around with this message at 02:25 on Nov 9, 2020 |

DreadLlama posted:Anyone buy from droneelite.ca ? They have a hexacopter frame kit I can't find anything wrong with. Are they a scam? Maybe not a scam, but it seems overpriced and outdated, especially the radio system. Is this for the seed spreading project? I'm not sure how much the hexacopter factors into the total price, but you could substitute the following to potentially save a little money and have better equipment that is still relevant today:
I'm not well-versed on large, heavy lifting platforms, so I can't really provide advice on the hexacopter itself, but I wouldn't be surprised if there are much newer, better motors, flight controllers, and ESCs that cost the same or less. Tarot X6 frames seem to be expensive no matter what, though.

Yes it's for the seed spreading. I got to thinking of my swamp and how people keep getting stuck in bogs. https://thepostmillennial.com/14-year-old-ontario-girl-dies-after-horse-gets-stuck-in-marshy-bog-outside-hamilton I don't know how my physical fitness compares to that of a 14 year old girl, especially one who horseback rides, but getting stuck and dying in bogs is a thing that really happens in 2020. I'd rather have a silver maple mangrove. But as I've previously indicated, I'd rather err on the side of precision when it comes to distribution, lest someone get mad at me for ruining their basement and/or sidewalk. People are always getting into fights over silver maples. https://www.lexology.com/library/detail.aspx?g=a4b24e51-b52a-4761-954d-934df9fdec2a quote:In this case, the plaintiff homeowners brought a nuisance claim against the City of Ottawa for damage to their home’s foundation, which was allegedly caused by the roots of an encroaching silver maple tree.

Radiolink is cheap, but will probably do the job and what looks to be a clone B6AC charger, which frankly, is redundant. Can you fly the profile you want to fly, line of sight? Also bear in mind, you're essentially making an airborne lawnmover. Is this in a populated area? And since you seem to be in Canada, you'll also need a basic RPAS licence AND need to be in class F or G airspace to fly this. Alternatively, hire a helicopter company and have them fly you over the property while you seed. It'll cost you less than that kit and be done in 30-40 mins.

Define "populated." There is a road nearby. A car goes by at least once every two hours or so. There's a rabbit I have to yell at to get out of my way sometimes. A helicopter company would be useful for one visit. But if it's legal for me to use a drone for inspecting maple sap line... How do fpv laws work in Canada? Are you LOS if you are near your drone but wearing goggles? Is this legal in Canada? https://www.youtube.com/watch?v=Z8hGgLLckp0 Did you know there's a multi-spectral image sensor aimed for agricultural customers called the parrot sequoia? There's enough of a market for people wanting to look at plants that they make a sensor for it. Are Canadians excluded from using such things? I mean, is one technically line of sight at altitude? How does that work? Can Canadians fly fpv? edit: grammar Double edit: Please do not tease me with phrases like "flying lawnmowers." Do you know about giant hogweed? I would love a flying lawnmower.

Well, it could be simple or it could be complicated. Just saying that you're about to jump into a big rabbit hole. I'm not a multirotor guy. I operate fixed wing and single rotor (Helis) The Parrot Sequoia uses modified infrared camera. They're available in various formats and you can even DIY it, if you're adventurous. I have one of these: https://www.mapir.camera/collections/survey3/products/survey3n-camera-orange-cyan-nir-ocn-ndvi Sounds like you're pretty remote. But you're still limited to line of sight.(Legally). You cannot fly FPV without a spotter and you're limited to 120meters AGL. To use any RPAS BVLOS in Canada, you'll need a SFOC and you wont get that without a manufacturer certified RPAS and a Advanced licence...and a good reason to do so. I believe the Sequoia is manufacturer certified, so there's that

Probably this? http://www.align.com.tw/helicopter-en/trex600e/ A much better quality option (which I've based my electric heli on) is this: https://www.thehelihangar.ca/collections/soxos/products/heli-professional-soxos-600-kit But honestly, unless you have experience with pixhawks or RC helicopters, this is a hard route to take. Build a medium quad rotor rotor first, make all the mistake that people make and it wont break the bank and is unlikely to kill you. Trying to jump straight into making a utlity AG drone is very hard. A 900 size hexacopter or 600+ single rotor can easily kill you if you screw up.

So you couldn't build a 350 and expect it to feel at all the same as 600? edit: on the subject of building medium sized quads: Is there an easy way to tell the difference between a faulty telemetry radio, a disconnected telemetry radio, and a telemetry radio incompatible with your ardupilot? Mine just says "no signal" on the monitor, which means it's at least seeing the fpv vtx. But I'm not getting data from the FC, even though I can via usb. I have something that used to be a Cheerson CX-20 but now has an ardupilot 2.4 or 2.6. I kind of gave up on it and then the laws got more restrictive in 2019. The old FC did some wonky thing where it would jank really hard in one direction when I switched to gps mode. Having the gps mode on when it took off meant it would try to take off horizontally. I still have that thing. Would you suggest I take another crack at it? DreadLlama fucked around with this message at 05:00 on Nov 15, 2020 |

Oh sorry, misunderstood. No, you can learn how a RC heli works with a 350, etc. You can stick a pixhawk on a 180 even. Of course I can't find the link right now, but here's a 300 https://discuss.ardupilot.org/t/just-sharing-my-blade-300-electric-heli-setup-using-kakute-f7-mini-v2/64047 Ardupilot 2.4 or 2.6 is ...well, at least 4 years old. Get the latest arducopter version on it, set it from scratch. There's no easy way of troubleshooting telemetry radios. There's some complicated ways, but I've never had and would rather just use a different set of radios. If you're getting no signal on the monitor, then you probably aren't seeing the VTX.

Oh, no. The monitor displays the camera output and there's white text on the screen that says, "No Signal" I figured I would be better off starting with a 32-bit system from the get go - no more cobbling together parts that are years apart in manufacture date. Just buy all the gear from one vendor so I know it all works together. I mean, I feel a bit stupid because one of the reasons I got rid of the FC that came on the CX-20 was because I wanted to put an optical flow sensor on it. Then DJI puts two of them on the mavic mini. I'd love one of their agridrones but I can't afford one. DIY is as much a matter of economy as it is proving I can build something if the parts are all compatible. Do you think a 180 could handle a gimbal and camera in addition to a pixhawk? I am thinking that I should build a small helicopter and then build a large helicopter if I have enough fingers remaining to do so.

# ? Nov 15, 2020 08:39 |

The optical flow sensor on the DJI's are far superior to anything you can get for Ardupilot. They're mostly a novelty when it comes to ardupilot, although there has been some improvement in sense and avoid over the last year. DJI has also totally killed the stand-alone gimbal market. If you want a gimbal drone, by a DJI. You'll need minimum a 450 to carry a gimbal and a small camera. I spent ages trying to do a DIY for my first heli (A 450) and it sorta worked. A 180 can just about carry a tiny analog camera and a VTX...and get you maybe 5 minutes flying time.

A 180 is a good platform to learn to fly RC helicopters on. 'Cheap' enough to repair (You will crash it..many times), big enough that most of the skills will translate. This is supposed to be really good: https://www.buddyrc.com/products/omp-hobby-m2-rc-helicopter-v2-version-omphobby-m2-v2-preorder?variant=33002410737750 I've been tempted to get one. Learn to fly LOS, being able to hover, fly circuits, etc. If you really want to build a heli-drone, you really need to be able to fly one without the FC bailing you out, because you will make mistakes a long the way and will need that skill. You can then probably jump straight to a 6-700, get it flying (with the FC), learn to turn it, run auto-missions, etc and then you can start playing with equipment and payloads. Optical flow, LIDARS, etc are mostly useless for your purpose. If you are flying over trees, they will give false readings. You'll have a bunch of issues with video equipment, although longer range digital video is coming along, but it's still not simple, nor cheap.
