I've always heard that you shouldn't discharge a lipo below 3.0-3.2v, that makes sense.
what about voltage sag under load, is it fine for the cells to go under that range during a heavy burst load?

I bought a completely overkill hobbywing max10 g2 (rated 150A continuous 880A peak) for my short course truck and the data logs are showing it going below 3.0v per cell sometimes when I'm near the end of a pack, pic rel, 5.8v @ 154.8A. on my shittier zeee 2s lipos it's even worse, I've seen 5.2v.
it's set to max punch and the battery cutoff is set to the highest.
>>
>>2842380
This one kinda depends. If you push any LiPo too hard, it'll get hot and puff, but if you look at tinywhoop stuff, those batteries often sag down to like 2.8V and then recover to 3.5V and do just fine. I'd recommend testing it all out a bit. If your pack is getting uncomfortably hot, maybe add another pack in parallel if you can. On another note, how thick is your wire?
>>
rusty wires
>>
>>2842410
12awg for both esc and all my 2s packs, stock XT60 connectors. they're all hardcase so I can't get a great temp reading but, they don't get that warm
>>
>>2842497
K, that'll probably do fine.
>>
>>2842380
also keep in mind that the value is at the point of measurement. not at the actual cells
>>
What RTR 1/10th scale truck should I buy?
Also what is best for long grass - ground clearance? I have a 1/16th HBX but it struggles a bit on all but the shortest grass. Still not quite sure about truck vs truggy here. I'll mostly be using it in a field but occasional dirt and beach usage

vague wishlist:
> 4wd
> brushless
> oil shocks
> metal gears
> fast
it would be a bonus if it supported 4S as I could use my quad batteries on it too (3000mah lion packs). but seems like most are only 3S.
>>
>>2842893
Are your Li-Ion packs 18650s? If they are, they're probably built out of Murata VTC6 cells which are only rated for 15A continuous. RC cars/trucks can call for a lot of amps really fast. Might wreck your cells.
>>
whats the best Tx protocol iyo?
>>
>>2842947
Right now it’s hard to recommend anything except ELRS.

If you’re doing *super* long range then the antenna tracker products/integration of Dragonlink is still superior, but 99.9% of people don’t need that.

If you’re doing MAVLink stuff then RFD (with the TXMOD option for RC control) is far more mature than ELRS’ MAVLink support.

But for general hobby use, ELRS is the clear winner right now.

what do you want out of it aside from performance on grass? handling, speed, tricks/bashing?
my three 1/10 sized rigs can handle grass fine to varying degrees.
rustler bl2s is light and low with wide tires not great but ok. can't handle thick taller grass very well
pro4 sc10 with proline trenchers does pretty good but, I haven't driven it in a lot of different grasses yet as I just got it setup a week ago
my 6s typhon doesn't give a shit and flies through grass, its weight and skinny tires seem to help traction a lot. even on slicks it'll walk its way out of grass most of the time.

take a look at the arrma vorteks/granite 3s, team associated MT10 and pro4 SC10, arrma typhon 3s, maybe redcat's Valkyrie MT or TR.
> metal gears
i know the associated and arrma ones have plastic spur gears at least.

>lion packs

ELRS or multi (Open TX or Edge TX) is what you need on this day and she. I like Crossfire too, but most people do not use this as a primary radio system.

Hip Hop is the best protocol for extremely small micros (see 1:96 RC P-51).

Single protocol is old hat, at this point, but any of the Futaba protocols, Graupner's HOTT and Multiplex's M-Link systems are the best ones. That said, for the love of God do not buy a Spektrum DX from the late 2010s or one that runs on DSM2 early 2010s Spectrum's are alright, though.

When you say "Hip Hop", are you referring to an actual radio protocol, or FHSS? If I look it up, all I find are internet radio stations for the genre.

As for the multi protocol chip. I've not used that thing once since moving to ELRS. The only time I've had a partial signal drop was five miles away when I turned my battery in front of the antenna. CC2500 would drop if I merely flew behind my house or even thought about a failsafe.

>>2843315
It is an actual radio protocol, I should have made that more clear.

It is a very niche radio protocol.

not from my experience but i order all my stuff on aliexpress
>>
>>2843331
Generally not, I would rarely charge a battery over 1C, except for a Graphene, which should be able to handle 2.5C.

I usually take graphene battery C ratings at face value, but standard LiPos, I usually divide their started performance by 2. C rating is a meme, mostly.

>>
>>2843349
DSMX mod with AS3X+ and SAFE compatibility. Or a multi/ELRS/Crossfire swap. You will need a lot of parts for the swap, though.

Speaking of Spektrum and Horizon Hobby in general. I have an E-Flite X-Vert that I cannot figure out how to set up for my TX16S running OpenTX. Does anybody know how, I want the stabilized vertical move to assist in landings (tailsitters make me nervous).

Seems pretty interesting, but price stings a little.
>>
>>2843331
I wouldn't do it unless I was outside, had cash to burn, and I needed to bang out packs for race practice. Have charged at 2C for my entire time in the hobby and have never had much for degradation. For bigger packs, I slow down to 1C or less if they start to warm up. Don't burn your house down just so you can charge in 10 minutes instead of 30-60.
>>
>>2843487
It is, I think it is made in the U.S or made in small batches, hence the price, compared to Plantraco which is mass produced (still pricey though).

There is a reason why 900 MHz is uncommon.

>There is a reason why 900 MHz is uncommon.

Crossfire, R9, Dragonlink & RFD have all been around for ages. Before ELRS (which can also operate on 900MHz) probably half the people I flew with were using Crossfire. It’s not uncommon or expensive.

I posted this on /toy/ but after being told about this thread I am asking again here. I would appreciate any help.

I've been wanting an RC car for a while and I saw some Tamiya cars that looked cool at my hobby/toy shop.
I've never built an Rc car before but I like painting fantasy miniatures so I have an airbrush setup and lots of acrylic hobby paints in little dropper bottles and pots. Can anyone tell me what tools, parts, batteries, or controllers I would need to buy in addition the the kit itself?

I would get one that's already built but I think if I built one myself it would help me understand the machine better if something broke or needed to be replaced. Also I would feel more connected to the car if I built and painted it myself.

pic rel was taken at the hobby store I get my miniature stuff from.
Some cars I like are the grasshopper, hornet, frog, blitzer beetle, rising fighter and neo fighter. I also heard about the new hornet evo which also has a cool shape. Something lightweight since I ride the train everywhere. My cousin has a traxxas rustler that I used to play with a decade ago but I remember it being massive and really heavy. I think a light buggy that fits in a tote bag would be ideal.

I plan to drive around the park or on the slopes of the woodsy hills behind my house. I don't care much for super high performance or speed but if anything, I would prefer good handling so I don't flip over. As for the plastic covering, should I get masking tape or any other kind of adhesives for assembly and painting while I'm at the hobby store?

basic hand tools, exacto blade, most tamiya kits are all phillips or JIS so use something decent, standard snippers work fine but if you already have flush cuts use that, polycarbonate specific paints are a must(unless it's a hard plastic body) I'm sure you can look up lexan paint prep and go from there with the painting exp you have, 1.5mm 2mm and 2.5mm hex drivers may be needed, a hair dryer is nice to have when applying decals, removable thread lock for at least the servo, double sided tape.

for electronics you'll need an esc, motor, standard size servo for the 1/10 kits, receiver + transmitter with easy end point and expo adjustment (flysky FS-GT5 as an example). some tamiya kits come with a basic hobbywing esc + tamiya brushed motor which are just fine to start with, should say on the box.

basic upgrades I'd recommend right away, CA glue + tire foams are a good idea, and a bearing kit so you don't need to tear it down all the way if you want to replace the plastic/bronze bushings later. also some tape on the inside anywhere the body touches something so it doesn't rub thru, like the body mounts. oil shocks are nice too but, I'd just feel out the kit as it is stock and upgrade as shit breaks (it will) or when you feel the need.

>should I get masking tape or any other kind of adhesives for assembly and painting while I'm at the hobby store?
I can't vouch for all the kits but my tt02 (picrel) came with window masks, if you want to do something that isn't box art grab some masking tape, tamiya makes some.
>traxxas rustler..massive and really heavy
check dimensions, I'll bet they're close.

1/2
>>
>>2844389
2/2
for batteries, 6 cell Nimh or 2s lipo with a tamiya connector + a decent charger.
tldr of batts; nimhs are heavier, less power dense, cycle life is higher, less fuss overall. lipos preform better and are lighter, but you need to take care of them a bit more than you would a nimh, needs balance charger, storage charges when not in use, low voltage protection set on esc, they're also potential fire hazards.

as much as I like my tt02 and will build another kit someday, tamiya kits are cheap plastic and aren't that great performers stock. expect breakage and upgrades later on as you use it.

2nding for this. DJI stuff is fantastic and insanely easy to pick up and learn. The tracking is ace and the automated control is perfect. Have a couple hundred hours on my mini 2 alone and still recommended it to everyone.
>>
>>2843758
True. Some of those are 915 or 833 MHz, though as opposed to true 900MHz. Crossfire is 915, I believe, bit do not quote me on this.

It is kind of splitting hairs, really, but I guess 900 is a family of frequencies.

On a separate note, I need a paint to brush by hand that is as light as possible. Would acrylic ink work instead of paint?

This is for two RC models that each have a target weight of 500 grams and I need a good metallic finish for one of them.

When people refer to 900MHz in relation to RC, they are referring to the 900MHz ISM band in general & not to exactly 900MHz.

In ITU region 1 countries (Europe) a 900MHz RC link must operate around 868MHz, while in ITU region 2 countries (US) it must operate around 915MHz.

Unpacked my old larvax, which I'd stopped using after my jumper t16's ribbon cables went fucky. Since then I fixed it but everything got deleted.

I'm trying to bind it again, which seems to be working. (its the frsky version) i know it's the old firmware that works with the multi module because it worked before and i certainly haven't updated it. I get rssi telemetry, but I can't arm the thing.

In mixes I have it set
ch1- throttle
Ch2-aileron
Ch3-elevator
Ch4-rudder

Thanks. I let my cousin talk me into buying a rustler 2 wheel drive with all the stock parts. It’s a RTR bundle that comes with a charger, radio control, battery and all assembled. I’m kind of worried that I’ll run out of battery in the middle of using it and then have to go back home. (The place I plan on using it this week is about 2 hours away).

I’m still waiting for it to come in the mail but I am planning on going into the city this Saturday. There are many hobby shops but I have 2 in mind: 3300mAh 8.4V 7-cell hump NiMH Battery, Series 3 Power Cell and the 3000 mAh 7-cell flat.
Is it overkill to bring 2 fully charged batteries? I won’t be punching it full blast the entire time. In the event that both stores are out of stock, are any other batteries or brands worth looking into that are compatible with a rustler and the charger that comes with it?

This is from their website: Rustler includes a powerful 8.4 volt 3000 mAh Traxxas Power Cell rechargeable NiMH battery pack to reach its 35+ mph top speed. Fast 4-amp charging is available virtually anywhere thanks to the included 45+ watt USB-C battery charger with iD® technology. Power adapter and cable sold separately. For maximum charge rate use Traxxas 2912 45-watt power adapter and 2916 100-watt power cable.

>>
>>2846470
>For maximum charge rate use Traxxas 2912 45-watt power adapter and 2916 100-watt power cable.
lemme just save you some trouble should you go this route as my buddy did, traxxas were cunts and limited their usbc nimh chargers rate on anything but their own usb power brick. even with chargers of the same or better usb PD specs, on the same usbc cable, it wouldn't do the full 5amps rated. we probably tried 8-10 usbc pd chargers before he bought the traxxas one, finally giving ~60w at the wall compared to maybe 20w.
I fucking hate usbc power standards so much.

invest in a decent mixed chemistry charger if you still like the hobby a month or two from now and want to expand to lipos or charging two packs at once, etc. oh and don't let traxxas' marking make it sound like you're stuck with their batteries, companies make packs with their connector, SMC comes to mind.

>Is it overkill to bring 2 fully charged batteries?
lol no, but for someone new that'll give a decent enough run time.
>>
>>2846484
Thanks. How long does it usually take to charge one of the batteries I mentioned from 0-100? I have no idea since I used to just use my cousin’s car.


Can you recommend any brands for charger or battery me to look out for? I live in South Korea and while there are hobby stores in the capital they may have different brands from the USA or charge more for NA/EU products. My cousin also said that wheels make a big difference too and linked me to pro-line racing.

I can look around myself but my biggest fear is that I get a piece of kit that isn’t compatible with my car. I’ll probably get another traxxas battery since they’re pretty cheap over here.
>>
>>2846471
>Are there any open source diy drones that can do the whole follow-me-take-pictures gimmick reasonably well?

The short answer is no. A DIY approach simply can’t achieve that level of either hardware or software integration.

While it’s theoretically possible to DIY an open source drone that does some semblance of CV follow-me stuff, it will be many times the size/weight, cost many times as much & it will be a horrifically clunky setup that never even comes close to the performance of the commercial offerings.

If you want a tiny follow-me drone, the DJI Neo (announced yesterday) is exactly what you want.
>>
>>2846492
>Can you recommend any brands for charger or battery me to look out for?
I like my gensace imars d300 no complaints (doesn't come with a traxxas battery plug, you'd need an XT60 male to trx female adapter), i don't have any other charger worth mentioning so I can't say much more.
>How long does it usually take to charge one of the batteries
eh like 40-60 mins on a 1C charge rate. 1C example; 3,300mah pack charged at 3.3amp, or a 500mah pack charged at 0.5amp, 10,200mah pack at 10.2amp etc.
the lil traxxas usb c nimh charger with their psu does like 1.5c-ish
>pro-line racing.
good but pricey, the traxxas stock stuff is alright for the lower powered stuff like your rustler.

oldfag who never posted on this board before but wanted to say hi.
these are my 1/10 cars
I built the bandit vxl into a cope rustler/slash, then I bought a slash and put the vxl electronics in it with a 272r transmission. I'm waiting on some slash vxl axles before I even attempt to run it on 3s.
I'm considering an lcg chassis swap for the truck, kinda just want to build it to do a bit of everything. most annoying thing is it just wants to dive and roll on tarmac, but I'm hoping the chassis and some thicker shock fluid/swaybars can help.
thanks for reading my blog

Long grass you would want bigger and wider tires but it's really only a problem with cheap 1/12th or smaller cars. Get a 3s/4s basher and go nuts.

yeah that's what I did to my 4x4 bl2s rustler (bought it before I knew any better), swapped it, and my other 2s stuff, to xt60. horizon does similar shit with their "smart" batteries but, at least their IC plugs are backwards comparable to EC plugs.
it's a shame they're such assholes about patient trolling (sealed receiver box and inboard shock legal bullshit) cause they have some decent stuff.

lcg chassis makes a huge difference. if you don't punch the throttle to hard those axles should hold up on 3s for a lil while.

I've seen a lot of people say they like traxxas products but hate how they do business and I get that.

My rustler came in the mail and it works fine so far but the NimH battery doesn't last as long as I would like. I got a charger capable of nimh and lipo charging and a Chinesium Lipo battery. The guy at the store put a traxxas converter on it for me so it could connect to the rustler. I tested it and everything and it works fine. Both batteries charge and work with my car. My cousin told me I should look into getting better wheels eventually or make space in the chasis for a bigger battery if I want. I haven't driven it with the lipo battery yet, I only tested to see if it turns on and runs.

But my battery charger has this button that changes the charge rate I think.
It lists
4a 100%
3a 75%
2a 50%
1a 25%
I don't know what to set it to so I just leave it on 1 to be safe. My lipo battery is 7.4v, 5200 mAh 50c. The nimh traxxas battery is a 8.4 volt 3000mah battery. What should I set the respective charge rates to? Please don't start a fire in my bedroom guys, since people have told me that Lipo batteries can be catch fire if I mistreat them. My cousin says he never charges his batteries overnight but I'm not sure if he's just being cautious/paranoid or if that's just standard practice.
>>
>>2847019
Can you take a photo of your charger for us, or tell us the brand/model?

>My cousin says he never charges his batteries overnight

The number one rule of LiPo batteries is that you NEVER charge unattended.
>>
>>2847019
The 4 amp charge rate isn't even 1C for the LiPo. I tend to charge all of mine at 2C. Would be feeding that sucker 6 amps. But yeah, treat lithium batteries with respect or they'll fuck you up someday. I charge in a steel drawer with sand and gloves at the ready. Don't think a CO2 fire extinguisher will help with those as a lithium fire will rip the oxygen off the carbon and burn hotter.
>>
>>2847019
remember to turn on LVD on the ESC when you run the lipo.

>>2847103
So you're saying I can charge my lipo battery at my charger's max setting without reducing the lifespan or causing either of them overheat? right? as for the traxxas 3000mah battery, the ideal rate would be 3 amps, if I am understanding this correctly.

Also is there a way to know if a battery is full or not? I don't have any way to check. If I charge my Lipo battery for about 60-70 minutes at 4amps would that be enough to go from 0 to 100%?

> lipo battery at my charger's max setting without reducing the lifespan or causing either of them overheat? right?
no, it can't output enough power to put it at 1c or above. outside of internal cell damage and a failing charger that's out of your control that rate is perfectly fine for that battery. I charge my 2s lipos at 2c (10.4amps) and occasionally 16amps when I'm impatient
traxxas rates all their nimhs that are above 3000mah to 4amp. in my experience some nimh packs will have their charge rating on the pack itself, I have a couple that say 3amp max and are 3000mah.
https://traxxas.com/sites/default/files/HKC18010-R05_2970X-TraxxasID-4amp%20AC%20fast%20charger-INST%20-%20EN.pdf
feel free to charge slower if you're in no hurry.

>Also is there a way to know if a battery is full or not?
when your charger says 100%, downside of a charger without a basic screen. something like picrel or a multimeter, a 2s lipo is 8.4v at a full soc, 4.2v per cell.
>>
>>2847298
Thanks, I appreciate it
>>
>>2847293
>Also is there a way to know if a battery is full or not?

The charger will stop when the battery is full - that's what the 'cell terminate voltage' is. Hopefully it will beep or something, or maybe the lights will just switch off. Have a look in the paper manual if there is one in the box.

Just make absolutely certain that you select the correct battery type.
>>
>>2847309
thank you for the info. it seems simple enough
>>
>>2847293
I just realized that I got your two packs mixed around halfway through what I said. 6 amps was incorrect. I meant to say 10.4 amps. Bear in mind that a properly stored LiPo will be around 25% charge, so it'll probably get done in about an hour at full speed. I'd recommend a better charger.
>>
>>2847366
for some reason my traxxas battery isn't charging well at all. I leave it plugged in for an hour and then I when I test it, I hold down the gas for about 8 seconds then it slows down and stops.

Now I know you wouldn't normally floor it the whole time but why is this happening?


>get a better charger
If my battery can handle a stronger feed then I probably will, as well as getting a second lipo battery. but I want to use my current lipo until it dies to see the charging issue with the traxxxas battery persists with my Lipo battery.
>>
>>2847375
>for about 8 seconds then it slows down and stops.
that's the nimh right? if it is the voltage is sagging enough for the low voltage protection on the ESC to shut it down. switch it over (solid red light iirc) and try again. do not forget to switch it back on for the lipo otherwise you could damage it once it gets low enough.
>>
>>2847383
>it once it gets low enough.
the lipo's voltage gets low enough*
>>
>>2847383
yes it's the NimH. The speed control light was blinking red before I turned it off then on again. It was solid red and when the battery was empty again, the light would turn off every time I hit the gas.

The motor makes a sputtering/rattling noise like a purring cat or a growling stomach as well when I hit the gas but I assume it was just struggling to spin with no power. The wheels were turning just fine though.

You'll want to discharge your LiPo batteries back to storage voltage after use to increase their lifespan and lower the risks in storing them etc etc, depending on your charger and battery capacity this can take 5 minutes to hours. I want one of these very soon.

Are you talking about something with 3 wires? (It'll be the number of cells +1.) If you are, that's likely your balance lead. It makes sure that your cells don't eventually end up at wildly different levels of charge. Having imbalanced cells can cause dangerous levels of overcharging and overdischarging.

Is free flight welcome here?

I am going to make a free flight hang glider from some old plans. I will post my progress and results, as well as the plan itself.

My version is downsized to be "pistachio scale" or about 8 inches.
>>
>>2848227

Sounds cool. I've heard of slope soaring but not rc hang gliders. Do you payload an fpv camera or just fly LOS or what?
>>
>>2848276
It is not RC, unfortunately, but it flies and could be converted to RC, if you used a servo to animate to pilot's arms. Think RC paraglider or skydiver more than an airplane. I would probably blow up and time the plans to make an RC version, which would have a 32" wingspan and use 1/4" balsa wood instead of the 1/16" that I will be using.

No battery will be on board so LOS. The model will be dropped instead of thrown sure to the nature of the Rogallo wing (which is really easy to make).

A Czech company, Hiesbök, makes am RC model that features a Rogallo wing called El Rogallo. It is the only commercially available RC model with a Rogallo wing.

The balsa can be no smaller than 1/64" thickness, so I need to keep that in mind.

for regular LOS flight I'd say about 150 to 200 hours, for piro flips and other tricks it's more like 500 plus hours on the sim, having a good radio and setup helps. Using mikado vcontrol touch with a mikado simulator interface and rx2sim USB device. You just gotta crash until you stop crashing basically, which can be in the thousands.
>>
>>2849813
Also when I say LOS flight I mean in all directions, you have to be able to fly in all orientations and that takes time, for more simple stuff it's maybe 150 hours but If you get into an orientation you are not comfortable with, the chance of crashing skyrocket, so just fly in that orientation till you stop crashing, it's how I learned anyways and watching auggie copter tutorial videos, he opened the door for me. Believe it's linked in the original post above. But I understand most people dislike helis for this reason, I just find it more of a meditation at this point and stress reliever flying helis as it's more rewarding and i can fall asleep doing these tricks in my head instead of counting sheel. I see it more as a gift now.

It's the rustler fag again. My cousin told me that the XL5 ESC that comes stock with a Rustler cant handle an 11.1v battery, which sucks since it limits what batteries I can use or buy where I live.

What would be the next logical step up for an upgrade? I live in East Asia so some western brands might not be easily available.

Also I have this traxxas nimh battery that came with the car but it wont charge on my dual charger (which charges my LiPo battery fine). The traxxas charger it came with needs a car cigarette lighter socket but I don't own a car. Will a cheap Chinesium AC to DC adapter let me plug it into my wall just fine or will I end up burning my apartment complex down?

Marder guy here, so I did my research, I ordered it. A bunch of French guys did reviews.

Reason I’m interested is because electric Is a bit boring, all it has is speed and acceleration but gas has SOVL and it makes boomers sneed from what I hear, also I prefer 2wd because I like the challenge of spinning out and crashing unlike 4wd.

You can pair a gopro with a harkrc gimbal (thats what I did, on an edu450 frame). Some nice Sony cameras have a connection allowing them to be integrated into a single board computer (https://support.d-imaging.sony.co.jp/app/sdk/en/index.html). Its what the cartography variant of the Orlan drone uses.
You could buy a dji but you'd learn nothing about building drones.

You forgot the part where every module has to be certified to be legal, so they're all expensive as fuck when they could use off the shelf stuff that people already have. They did everything they could to make people hate it.

thanks for admitting it doesn't do anything for safety, which is the excuse they use to restrict the hobby.

>They did everything they could to make people hate it.
That's intentional. I'll just leave it at that.
>>
>>2851570
Are you referring to the theory that the FAA also thought it was a stupid idea, but were required by Congress to implement it, and so they intentionally did a shitty job? I mean, it's not too hard to believe. People involved in aviation do tend to be a little sharper than average.

>you did that and no one died?
Just me and a drone in a large empty field? All that happened is that I put it in 'stabilize' mode (only using inertial sensors) and kept pushing the wrong knob to put it in the mode that uses the GPS. There was never any danger of a flyaway, it was just a rough landing.
I do, however, know some retard in academia with all of the necessary permits who has two flyaways, one of which landed in the middle of traffic in the city center.

I don't know if the FAA thought it was a stupid idea, but I can tell you for a fact that the implementation being horrific is intentional. It is designed that way to deter which it does.

I will work on them, but they are usually for models that are much larger, so I might just link some PDF downloads. I will show Ugly Stik, Tiger, Falcon, Kwik Fli and Kadet plans. These were all will known designs from the 1960s and 1970s and require either a .40 or .60 2 strike nitro engine. My recommendation is O.S, for nitro or electric. Electrifly also *had* good motors. The current ones made by Horizon Hobby (instead of Hobbico) are horrible.

For used engines, Enya, Fox, K&B, HB, Super Tigre, Rossi, Irvine and Webra are all good, but avoid Chinese engines except for Magnum and newer ASP ones.

nta but, yeah. there's a lot of bad info out there about laws and whatnot. like the bullshit lies I heard from multiple people about low powered analog VTXs <1W not needing a HAM license when in reality anything not FCC certified needs it. add in RID, no fly zones, and part 107 if it applies to you, and it can be overwhelming to anyone starting out.

reminds me of all the bullshit ATF laws that have no effect and only fuck over honest people.

And I'm back in the air, thanks!

Accountability is a big part of safety. People are less likely to do stupid/illegal stuff if there is a high chance they'll get caught.
>>
>>2851933
Tell that to the people on the road. I can take one 10 minute drive and see at least 10 people who are well below what I would call qualified to drive. I live in a low population area, and they seem to get worse in other places. RID isn't going to remove any tards.
>>
>>2851955
Except people get done for driving/traffic offences all the time. I don’t understand your comparison.
>>
>>2851955
Oh, my favorite lately is seeing people cut across 4 lanes of traffic to take an exit.
>>
>>2851968
Nearly every adult in America drives a car, as opposed to less than 1% flying hobby UAVs. How many have you actually seen flying something and got caught doing something wrong?
>>
>>2851933
and when they don't install the RID module?
>>
>>2852308
That's the funny thing, isn't it? Unless they're flying long range or from in a house or car, it's pretty fuckin easy to tell who is flying. Humans have these weird things called eyes that the government keeps forgetting about.
>>
>>2852339
One of the biggest issues is people flying in urban areas, where it’s pretty much impossible to find a remote pilot amongst the hundreds of buildings & thousands of people.

Another big issue is people using drones to drop drugs/weapons into prisons, where they don’t stick around long enough for anybody responding to a report to get on sight & see them.

In both of these cases, having RID hardware forced onto easily accessible COTS drones like DJI’s will have a noticeable impact. It doesn’t make it impossible to do bad stuff with drones & get away with it, but it stops it from being _so_ easy that any braindead meth dealer can do it without thinking.
>>
>>2852451
But then, everyone with a brain realizes that you can easily slap together a working aircraft with very basic parts, and skip RID quite easily. RID only hurts the well meaning pilot. I can build an airplane for $100 that will auto drop packages or even just crash land right at the site. I'm just some guy who tinkers around and doesn't really know shit. It's just that easy. Even if they take away the flight controllers, old phones, Arduinos, Raspberry Pi clones, and Wii remotes are all easy substitutes. Airframes can be printed, or built from wood or foam board. RID can't stop crime in the slightest.
>>
>>2852474
You give far too much credit to the general public. Building an autonomous plane for $100 & programming it to land/crash at a specified location is beyond the abilities of the vast majority of people. You only have to look at some of the questions that regularly come up on RC groups all over the Internet to see that even people who profess an interest in the stuff are often completely clueless.

Anybody can buy a Mavic, install an app on their phone & duct tape a brick of drugs to it. But task people with flashing iNav/Ardupilot onto a Matek board & you’ll lose probably 90% of people.

I’m not saying that what we do is super complex. I’m saying that the average person is fucking dumb.
>>
>>2852481
I fully agree with you that the vast majority of people are dumb as fuck. That said, the dumb ones don't tend to be that hard to catch because they make a million mistakes.
>>
Any other recommendations besides DJI ? Just to drive drone around. Recommendations for RC with screen too.

I got bored yesterday and tried to refurbish my ancient ~20yo integy 3300mah nimh pack that split in half and needed new wires due to corrosion, when I got it 5-6 years ago it was already like this.

first charge after 12v car battery shock and rebuild with xt60 and 12gauge wire, 578mah, ~50mohm. ~6watt discharge to 0.3v per cell 384mah
2nd charge 746mah 52momh, discharge 580mah
3rd charge 894mah 49mohm rest overnight for idle discharge check, dropped to 5.5v
4th 619mah 5Xmohm
discharged with tt02 torque tuned motor hw 1060 stock gearing to 6.2v, charged up 988mah 45mohm
discharged with tt02 to 7.5v, 1327mah 45mohm
discharged with tt02 to 7.7v, 1653mah 39mohm
discharged with rustler 4x4 bl2s on road to 6.56v, 2135mah 42mohm
discharged with rustler in grass to 6.5v, 1833mah 42mohm

doing a slow deep discharge+charge cycle with my charger again tonight just because. I hope it doesn't phantom drain again.
not sure I'll use it much if ever but, it was fun seeing the capacity go up.

Potensic.

So I've got a chink shit mavic 2 clone, advertised as 4k flying drone. Produces a wifi signal that wifi_cam can interact with. My question is, is there software I can use to interface with it that doesn't feel so much like spy ware. Has anyone reverse engineered one before?
>>
can I use the cameras that come with a DJI phantom for architectural photogrammetry or do I need something better?
