Here's a dumb question - I have a Quest 2, and I know I can cast from my phone to the headset so I can kinda bullshit FPV with my Mavic Mini. Is there any way to use the Quest 2 in a way that would give me head tracking, so I can look up and down and have the drone track with it?

In light of the current conversations something interesting happened today. I live in a shallow valley in the TX hillcountry with my house situated near a creek at the low point. Today an ultralight flew extremely low over the hills south of me, across the valley, over my house, and passed about 50-80ft ft above my neighbors house that is on a hill north of me. Thankfully I wasn't flying a drone but he was well under 400ft and I'm almost wondering if he took off from a neighbors ranch. I'll be watching to see if he comes back this way. Hopefully it's not going to be a regular thing.

I might be wrong, but I believe ultralights can fly at really low altitudes but can't fly over populated areas, so sounds like someone was doing the wrong thing!

He was probably legal depending on how legal it is to fly directly over a house and this area isn't exactly populated. Just surprised me and shows how hard it is to share the airspace. He also better be careful because he wouldn't be the first one to get low around here and have a nice controlled flight into terrain.

Part 103 ultralights (i.e. under 254 pounds, don't need a license) have no minimum altitude restrictions, the argument being that they stall at like 20 mph and can land in a baseball field so it's easier for them to make a safe emergency landing. They do have the catch-all rule that the aircraft may not be operated in a way that creates a hazard to people or property on the surface. The FAA uses the term "congested area" to refer to built-up areas, but specifically does not define exactly what it is. In various cases it has meant cities, beaches covered in tourists, crowds at airshows, etc. One farmhouse is generally not going to be considered a congested area. There's also the part 91 rule (technically doesn't apply to ultralights, but anyway) that you are allowed to fly lower than a minimum altitude restriction if required for taking off or landing. But you're right, it's surprising how many things there are going on in the air that you aren't aware of until you start trying to fly stuff there yourself. It's not just a big empty sky.

Thanks for the rundown on that. It's helpful to know what rules everyone else up there is supposed to be playing by also. And I'm calling it an ultralight because I think that's the category it falls in to but it was on the bigger side of that. I wish I had gotten a picture but he didn't come back by while I was home.

So I haven’t flown my Mavic in a while and I was really surprised when I went to charge the batteries up and neither of them would charge! Like they aren’t even two years old. Luckily DJI will replace batteries for free so I just shipped them off and should get some replacements in a few weeks. I’m just glad I didn’t have to shell out for new batteries since the OEM ones seem to be going for about $100 each.

Did you store your batteries empty or full? Both are bad for long term health. Chemical changes in li-ion batteries can happen in about a week of being stored fully charged or drained which will start to impact their ability to hold a charge. They'll also self discharge over time so they could've fallen to damaging low voltage. Storage charge them down to 3.8ish volts per cell when you're not going to use them in the next few days.

I’m just surprised they both ended up doing that when I have a lot of other electronics that are older and just fine  Hopefully my new batteries come in soon so I can fly again. Although there was another update which drastically increased the NFZ near my house so I have to walk a lot more to fly the drat thing.

Greg12 posted:whoa. I didn't know the "flying garbage" route was available. Funny that you said "flying garbage" because I took a model I made to an AMA field to fly and was told by another member that I couldn't fly there because my plane was "literal garbage". I flew anyway and when he crashed his EDF on takeoff I had to hold back the smug "No, *that's* literal garbage" comment. DTFB planes fly just as well as any other plane at that size and it is a lot more fun to have a plane of the month instead of blowing all your money on a $150-200 model that you're stuck with and even a single part replacement would cost more than my whole plane. A good list of the FliteTest plans are here. My first plane was the FT Arrow which lasted about a whole 20 seconds of flight across like 5 launches, but the FT Tiny Trainer is what I actually learned to fly on. The Mini Scout (not the Simple Scout) is also very easy to fly in low wind and also is only a single sheet of foam.

I wish you guys had fun AMA clubs in your area. The fun of flying for me is doing it with other people with like interests, then fly and break each other’s balls and have a beer. At any club I belong to, if somebody showed up with a cobbled together foamboard thing we would want to see if it would fly, then probably want to build one ourselves, even with thousands of dollars of gas wood airplanes to fly as well. As long as you don’t do anything dangerous or obstructive and pay your dues you are welcome. Being able to take a joke also helps.

Yeah it's definitely more annoying than useful. I mean chances are I'm going to upgrade my drone every 2-3 years anyway. There's no way that there would be a meaningful decrease in battery capacity from storing them charged, unless you literally only fly your drone 3-4x per year. But there's a very meaningful increase in my forgetting to charge that poo poo and then having no battery when I grab the drone to go somewhere.

What's the real world lifespan of a battery like that In my mind it would seem that the chemistry prefers at least a 25% charge/discharge every 3 months or so, but will put up with sitting on a shelf at 50% for a year

Sorry if "recommend me a drone" gets asked every two pages but I don't really know anything about them and my dad asked me to help him. Basically we are grain farmers with a fairly small beef cattle operation on the side. We're generally too busy during the rest of the year to bother with calving so dad times it so the calves are born in February-March. We have to keep an eye on the cows to make sure they're not having difficulties giving birth or make sure any just born calves aren't freezing to death when it's really cold. This involves a lot of walking around in fenced off fields of corn stalks in the bitter cold looking for babies. Dad wants a drone so he doesn't have to do as much walking/can cover more ground/see better from the air. He said he'd be willing to pay $1500-2000 (less is fine too!) Is there anything in that price ranges that's reasonably easy to fly, has a range of at least 1/2 a mile (preferably a mile or more), has a decent camera capable of seeing fairly long distances, and can operate for 20+ minutes in freezing temperatures? I know batteries don't play well in cold temps so that might be the big issue unless there's models with like, heated battery packs or something. Temperatures usually stay above 15F here in the winter but occasionally it gets as low as -10F if that matters. The camera being able to see well in low-light conditions would be a big plus too although I assume actual night vision would cost a few thousand dollars extra at least. Other than a previous roommate showing me his DJI Phantom very briefly I know very little about current drone tech and what it's capable of so I'm not sure if this set of requirements is totally ridiculous or no problem at all.
