When i was a child, my dad bought a foam plane for me once (the kind with a single motor propeller in the nose) and it was very fun to fly it. The only bad thing about it was that there was no remote control or anything so it would continue to fly straight endlessly.
Did you guys play with that kind of planes? My family was poor so i was only able to play with it once

So I have a picrel chinese POS drone called a JJRC x17 laying around.

One day, upon plugging the battery in to charge, the BMS gave up it's magic smoke and thus it became a paperweight.

I'm wondering, if I could somehow re-use some parts and build a FPV drone out of it. I'm an absolute novice with drone-building, but I'm quite handy with fixing electronics overall(except the damn BMS that's all SMD components and appears pristine apart from it not working). Some tips/guidance would be really appreciated.

>>2793173
I had one of those, but mostly when I was a kid it was those balsa stick and tissue paper rubber band powered ones. Of give the rudder a little bend so it would fly in circles.

it doesnt charge?

your best bet is to buy a new battery for it or open it up and solder a 3s USB BMS to the battery cells (you can buy em cheap on aliexpress)

i dont recommend reusing parts of it for an FPV quad unless you have experience building a quad from parts you ordered. in which case you could probably reuse the engines/props in some ultralight/long range FPV quad. or you could gut it and replace the internal electronics with an FPV AIO board + FPV camera and only keep the original engines

Oh yeah, it doesn't charge or power up the drone at all. If power is supplied, it blinks it's State-of-charge lights, but nothing really happens. When it died, there was actual smoke and it sent me scrambling for a baking tray in case it would go all up in flames.

I also had the idea to put a generic BMS in there, but I do not know the pinout for the connector and since the BMS board also has the power button, and some unmarked active components, I think it's a bit too involved. Also had no luck finding the BMS board alone on Aliexpress.

I really do not want to invest in a new battery, because it's about 1/3 of the total price and the stock electronics are crap, it's the GPS/compass on it that is really bad, it will wander and start toilet-bowling out of the blue quite often.

I really like the idea about gutting it and just keeping the frame/engines. I'm sure there will be some growing pains, but it doesn't sound too insurmountable overall.

Either-way, thanks a lot! Now I know my options better and have a better idea on what to research further.

pic is the problem maybe?

its probably a power distribution board that gives 3.3v 5v and 11v to the different components on those pins. at the top of the battery.

im seeing this drone for 160 on aliexpress and the batteries go for 30 im still thinking thats the best value youll get out of it is if you get a new battery.

you can take the old one and solder an XT30 connector + 4 pin balance connector on it and use it for some fpv quad or to power a radio/goggles of an fpv quad if it's weak.

>>2793188
Realistically there’s nothing to salvage. You could maybe reuse the motors, but you’d be stuck with those shitty friction-fit (?) folding props.

>>2793188
imo you're better off selling it and putting that towards a tinywhoop.
if you're feeling ballsy you could re purpose the 3s lipo into a flashlight or something.

Is this the right place to ask but I'm trying to get into helicopters but seems like a steep learning curve, how hard is it to control line of sight with it or do any tricks for that matter?

>>2793243
It's a bit tricky to tell from the picture, but the white thing is a glue-ish substance they used all over to secure stuff in-place.

You are absolutely right about the battery price though, I was using outdated figures or maybe my memory failed me.

>>2793260
>>2793274

Thanks, everyone, I guess I'll just replace the battery and gift the whole thing away, toss the BMS board and hold on to the cells for some DIY project down the road and get something like a Mobula6 for some indoor fun instead.

That kind of advice is a quick way for him to lose a quad. He obviously doesn't know anything about flying, let alone long range. Gotta learn throttle management, proper antenna configuration, battery types, the amount of effect weight has on a quad, how altitude changes signal propagation, return to home settings, and how to even actually fly close. I almost lost my first one because I didn't understand half of that stuff. It was luck that I got it back.

you could probably do this on a small drone with a microstepper spinning the screw. the problem would be needing to write custom firmware to stabilize the thing mid-transition.

or you could just have it run at a fixed throttle on all engines while transitioning while already having some forward speed from before. i think you could do with with inav vtol functionality,switch from the quadcopter profile to the plane profile and then engage the stepper to rotate the wing

i still think a tailsitter VTOL or tilt engine vtol is a better idea

>>2794763
>>2794698
AND its fucking dead
guess this is what i get for buying the first batch of experimental hardware. i thought it was less fragile since i saw people flying with them.
i think the thing is extremely sensitive to the input power and my shitty chinese bench psu fucked it up . in the github they recommend soldering an extra capacitor and a zener diode between the 5v inputs

i hope for the next gen they'll integrate such a diode into the PCB so the thing doesnt explode if i put 5.5v on it by mistake

>>2795039

I only remember like one of the stations which seemed to be some kind of truing stand type of thing i remember it had like a spinny plate and i think the workshop itself had like wood panelling round the walls but idgaf about that shit i just want to find out what the more specialized tools or jigs or shit were about

i sill have the 'regular' version on my big quad (was planning to replace it with the AIO).
it's pic related connected to a wifi chip and to the flight controller.

previously it was really a mess to try to configure it because there was no real documentation so i'd just mess around with random config files and most of the time nothing worked. now theres a configurator program which can also update the firmware which makes things way easier.

my current cope is that the regular security camera board version is better for big quads because i can put a high power wifi card i have on it and the AIO is just if you wanna fly it on a tinywhoop or 3 inch quad

Hmm. The cineape 35 looks pretty solid, but reviews say it has a 12 min flight time, while the foldape has 20 (and ofc a dji has 30 min flight time)

Can I tune these drones to get longer flight times?

Personally I wouldn't buy a pair of Goggles v1 today, because then you're stuck buying nothing but previous generation air units. Makes more sense to spend a bit more money on the Integra goggles, which are a 'budget' version of the latest generation.

The choice is between a

BabyApe Pro (~$150 w/ batteries + $80 for the controller = $210 total)

FoldApe ($200 with batteries + $80 controller = $280 total)

or a Flywoo Explorer
($260 + batteries and controller, est $370 total)

The FoldApe has a GPS, but I hear it has interference issues with the FPV signal. Does anyone have experience with the FoldApe4?

Everything feels the wind. If you're going to do long range, a mere 15 MPH wind will annihilate the range of even a 7 inch quad. I should know. I've been there and done that. If you don't want to care as much about the wind, get a plane.

>>2796658
I had a shitty full-sized brushed quad that did pretty well in "the wind" until it broke. My little micro drone can barely handle a stiff breeze by comparison. I guess it's all relative.

>whoop

I don't like the whoop frame. I don't like how they fly, I don't like prop guards, I don't like anything about them. Right now is an especially bad time to buy a whoop because the AIO boards haven't entirely caught up with the ELRS standard - some people really suffer over the UART vs SPI receiver thing.

bin the whole cart imo.

>>2797758
Seems fine to get started although I've only ever flown happymodel whoops. Whoops are for indoor flying, or flying outdoors in close proximity to people and in cramped / small areas.
Sure other goggles are probably nicer but depends on your budget.
If you are flying analog/whoops you have to be content with shitty video anyway.

Can I get around DJI geofencing by blocking the GPS somehow or will it not take off at all then?
I just wanna fly in an area that requires an internet connection but last time I was there there was no signal so I couldn't do the permission request thing. There is an airport nearby (not close) but I'm literally going to keep under 10m to photograph a building site.

I joined the baby ape meme, this thing is actually pretty good. Micros have come a long way since my last one (UR65).

Swapped the vtx out for one I had spare. With the stock one you can’t tilt the camera back properly because it fouls on the vtx connector.

>>2799169
yea its a good one, i got mine on a discount just because the price was so laughably low i thought id just get a spare drone if my main one ever breaks and i ended up flying it a lot more than i thought i would because i was less scared to break things and things are just easier with a 3 incher compared to 5/7.

Homemade underwater drone. Forgot to connect one of the motors to the ESC when the battery was connected, they somehow shorted and caused a fire in the airtight compartment. Luckily I got everything disconnected quickly enough so it didn't spread. This is the wire that connects through to the non-airtight compartment meaning all the sealing for this section now needs to be replaced too fml.

gonna give you a hint. DIY is almost never a cost effective solution, especially if you factor the value of your time. it can be fun to learn and say you did something, but ultimately it's best left to masochists,autists and poorfags that dont know any better.

can anyone suggest whats a good RX/TX pair for my homemade dirigible? would a rudder be sufficient to steer with one prop, or more props with different vectors of thrust. whats the best was to store/collect and store hydrogen from electrolysis?

I think it's worth building your first quad or two so you have a firm grounding and know how to make repairs. There are also form factors that are simply not available for purchase ready to fly e.g. X-class.

>>2801147
I have the radio in your pic, with my surface stuff I've had it cut off ~500ft out even with my ghetto rigged 12v milwaukee li-ion.

Thinking of building a long range autonomous fixed wing drone. I usually just build and fly quads so this is a little out of what I'm use to. My last fixed wing build was 10+ years ago using balsa and saran wrap.

Is there any good software out there that can be used to design/simulate coefficients, stability, etc? I really don't want to break out my uni text books.

Newfag here. I'm building the flite test trainer. I have to order the electronics, motor and transmitter.
No clue what to get within the recommended specs, I know I don't want to mount a flight controller yet, and I'm building the 3 channel version.
I saw the Radiomaster Pocket recommended here, but it's way over MSRP on Amazon and still above on AliExpress. Where do I buy all this shit? I'm in Italy, there's hobby stores nearby but I'm just going to get shafted there. I'm still fucking sore that foamboard is 5 fucking bucks a sheet here. At least I'm having a blast building.

Retard here. So ideally I want to do an unmanned/autonomous type setup for a drone that has some kind of docking station that I configure with a retractable cover outside. I want to be able to launch it with custom flight plans over some kind of interface. I don’t really know anything about drones but want to get into it. Started with the JB series linked here but it seems more geared towards pure FPV/hand controlled flight. I have a 3D printer and can design and fabricate stuff to a small extent. How should I get started? Is there a decision flow chart I can follow with simple answers or is it like “50 different flavors of chink shit that has the be grafted together”

>So ideally I want to do an unmanned/autonomous type setup for a drone that has some kind of docking station that I configure with a retractable cover outside. I want to be able to launch it with custom flight plans over some kind of interface.

What you want to do is possible but probably not for you. Ardupilot is probably the most aggressively developed open source autonomous flight package and that is your best starting point, but even state of the art commercially developed drone automation comes with caveats, deadfalls, and problems.

rctestflight is the premier youtube channel for this particular autistic pursuit.

since you are unfamiliar with drones/multirotors the first thing you should know is that flight time is minutes, not hours and whatever mission you had in mind is almost certainly ruled out by the laws of physics and/or economics.

>>2801812
Nice thank you that’s great info. I don’t have any crazy long flight times planned. I realized my original post was somewhat cryptic. I’m hopefully not a complete retard. I’ve got an ~50 acre plot in NH and I’d like to trigger automatic surveying runs of different pieces of it at configurable intervals. (Think something like checking the growth of plants). Ideally they drone would return home, upload its video to a home server and recharge until it’s next dispatch.

>>2801849
Yeah, that's gonna get difficult real quick. There are commercial options out there for just that purpose, but none of it is even remotely cheap.

>>2801807
I ended up buying that cart, with different goggles and some extra props, I'm pretty comfy with 6 right now with how quickly that charger can top them off @~2C, I can basically cycle them indefinitely with a short break between packs.
once I start flying more aggressively I'll definitely need some more.

I worked briefly with a commercial outfit that was trying to develop a ‘drone in a box’ solution for automated patrol/survey. A team of 5 or 6 very smart people with thousands of hours sunk into the project & it was still nowhere near viable.

yes, there are a few projects. but it's mostly for rough estimates and way less precise than GPS

I'm new in this subject but this summer I want to build a drone myself and i have some questions:

Why they use speedybee what's the diference between that and an arduino?

The drone will be good (usable with good performance not perfect) if i 3d print the chasis? In that case, what materials should i use?

I want to try different things like long distance dronning or using the drone to carry things like maybe a little box with some weight (just for fun nothing serious)

Maybe later in the summer i'll try to make a program to make the drone fly by itself so speedybee would be usefull in that case or speedybee is only for fpv race drones?

thanks for the anons

>>2802622

An arduino is a generic microcontroller. A flight controller is a microcontroller that has been specifically designed for drone hobbyists and has sensors and other features built in, as well as firmware and software (usually betaflight). Speedybee is one brand of flight controller that is commonly used to build tiny whoops.

No a 3d printed chassis will not work well.

No you will probably not be able to fly long distances or carry payloads with your first build.

No you will not be able to make the drone fly by itself.

>>2802635
Thanks anon.

But why doesn't it go well if i 3D print the chassis? Is it because of the relation between the weight and resistance of the material?

By carry payloads i mean stupid things like an egg that i can drop above a friend's house. Things like that, just for fun and to gain knowledge of how to balance weight in drones.

By making the drone fly by itself i mean short distances like a 5-meter straight line in my backyard, just for the same purpose learning about this subject, and maybe later the next year I will do something more serious with my acquired knowledge.

>>2802642
>But why doesn't it go well if i 3D print the chassis?

Because the materials you can 3D print with lack the fundamental properties that a drone frame requires - especially rigidity.

If you want to save money & still feel like you’re building something yourself, rather than just buying parts, hardwood dowel & aluminium box section are infinitely better than anything you can print.

>>2802648
Ok thank you for the advice.
I'll search for information and ask you guys if i have any questions. Thanks again for the help.

>>2802635
Some of this is untrue. A printed frame isn't optimal at all for vibrations, and explode when crashed, but is usable. There is also an option for semi-autonomous flight with waypoint missions on iNav. Many Speedybee brand flight controllers have iNav targets ready to be flashed.

>>2802847
>There is also an option for semi-autonomous flight with waypoint missions on iNav.
>Many Speedybee brand flight controllers have iNav targets ready to be flashed.

Didn't know either of these things. Thanks anon! Reading up now.

>>2802857
Not either of the above guys. Start off with something small and cheap, and something that you don't mind crashing and breaking (because you are going to crash and break it). 90% of your time in this hobby will be building and fixing, the other 10% will be flying and crashing.

>>2802862
Nah, if you go small, lots of crashing is possible with minimal to no damage. I built a 2" quad with a Happymodel X12, Bassline frame, 1002 14000kv motors, and a Caddx Ant. I've smashed the hell out of that thing and it has nothing more than a chip on the corner. It's plenty agile for its size and weight, so it makes for excellent, low risk fun. Very cheap too!

>>2802654
me again.
I want to save money and try things out. I know that is possible to connect a cellphone to output the live video of the drone and i was wondering that if i use one of those shitty goggles that you put your phone in to try VR would be a usable alternative to a $200 goggles.

Would it be usable, or it would be the worst experience in my life?

>>2792854
How do I get my Temu free drobe?

>>2802928
It’s only ‘free’ if you buy several other items you don’t want, which add up to the price the drone would cost anyway.

>>2802927
>one of those shitty goggles that you put your phone in to try VR would be a usable alternative to a $200 goggles.

no

>>2802927
The issue here is that your phone actually needs some way of getting a video feed into it. There's analog, which a phone will need an external receiver for, or there's the proprietary digital video systems that will cost as much as your phone did. Just start with figuring out what cheap analog goggles you wanna start out on. Latency is actually important if you're going to do more than hover in a field. Those analog receivers that connect via USB are not going to be a good time unless you're just spectating.

I just found out, by complete accident, that a HAM license is needed for pretty much any analog VTX in burgerland since anything worth using isn't FCC part 15 certified.

>>2803004

In practice nobody gives a single shit about miliwatt broadcasts in the 5ghz range as long as you employ common sense and don't make a nuisance of yourself. Flipping a lightswitch probably generates more radio than an FPV drone.

>>2803004
I got my technician's license, and guess how much it has mattered. Oh right, it hasn't. Waste of time, money, and effort. Nobody gives a fuck if you blast over 1W as long as you don't park it at like 5.5GHz and disrupt Wi-Fi all day, and even then, most won't notice as everything will just fall back to 2.4GHz. even if the rare HAM autist tries to hunt you down, they'll never find you if you don't stay for over 30 minutes.

>>2803117

dji mini 2 se, anything cheaper (that's new) is going to be chinkshit manufactured ewaste.
yes it's overkill but it's better than watching your sub $200 quad lose connection 100ft away and do a full power arch into the ground, I've watched this firsthand.

>>2803126
Many such cases. My first and last chinkshit quad did a flyaway at like 30ft away and almost took out a car

>>2803117
For cheap camera drones that aren't locked down, a Potensic atom or Fimi X8. Both have a 3 axis gimbal, 4k camera, and have good reviews. Stay away from holy stone brand. I had one, and have seen others, that have problems randomly flying off on their own.

>>2802642
I had the same questions when I got into fpv quads. A frame that's flexible will mess with the tune the fc uses to stabilize the flight. Also it's annoying to have to print new arms every time you crash, and you will be crashing a lot. A $20-30 carbon fiber frame can handle most crashes indefinitely and will get you flying a lot quicker than doing R&D on stl's.

>>2803107
They too work for free.

>>2803147
Hell, a 2-3 incher often has carbon frames for a mere $15. I bought two like 6 months ago and I still have the spare. Rammed it into a deck railing today at full speed and there's no visible damage.

You’re also quite likely to break components when you crash with a 3D printed frame, because wires will rip solder pads off PCBs.

It’s false economy to save a few dollars on a frame if it means you then have to buy new components.

And it really sucks to spend hours building a quad, only to have to rebuild the whole thing after 10 seconds of flight because you set something up wrong & it crashed on your maiden flight.

I have some questions:

Why does the video feed look like this when using FPV goggles with a drone?
>pic related

It's due to this?
>>2803000
What i understand is that the camera sends analog data directly to the goggles to minimize latency, resulting in lower video quality

How the drone does that?

Do you have any sources that explain how drones work in terms of radio protocols and video transmission?

>>2803559
The old analog standard works exactly like broadcast analog television, but at very high frequency. Digital ones just use well known video encoding, a specialized video processing package, and high bandwidth radios with a fair bit of error correction. They're basically all proprietary.
camera -> video transmitter -> video receiver -> display device

>>2803559
Not that anon, but analog video is different from digital video. I'm not an expert on it and I don't know all of the terminology, but analog video cameras scan top to bottom, left to right, and capture the amount of light received as an electrical value which then broadcasted over the air. This happens continuously (there's no pixels) and the process is essentially instantaneous, there's no computer processing involved. Since those light values are being broadcasted directly, the light and color values aren't transmitted as bits (on/off), they're continuous values (think volume with high, low, and everything in between), and thus susceptible to interference. The timing determines where on screen a given part of a signal is "rendered" as a color. It's basically instantaneous on the receiving side too.
Digital video is different in that it captures the light and color of each individual pixel on screen, converting the amount of light/color captured into binary values, repeats that however many types per second (usually 30 or 60), encodes those frames into a digital video format, probably compresses it too, then broadcasts that data as a digital (bits) signal. Since the signal is digital, it probably has an error checking system built in and is thus less susceptible to interference. With digital, essentially either the signal makes it from the tx to the rx or it doesn't, so it's much clearer. Also, you get more detail (depending on what resolution you use) than analog. However, all of those steps take A LOT more time to complete on both the tx and rx sides, hence the lag in digital video.
This YT series explains how analog video works pretty well:
https://www.youtube.com/playlist?list=PLv0jwu7G_DFUGEfwEl0uWduXGcRbT7Ran

>>2803572
Thanks a lot anon, very well explained.
Then i have another question, if I don't want to pay for the goggles i can get the signal with an LCD screen or a old TV.

like here: https://youtu.be/zuUq9DifmZE

What are the benefits of the goggles, is it all because they're more immersive and get you a better view of your surroundings while flying?

>>2803581
Couple points:
To my knowledge, drone video signals aren't broadcasted over the same frequencies that analog television uses, so you won't be able to get them on a regular TV. I think (not 100% certain) that drones use the same frequency range that wireless security cameras do, so maybe you could get some equipment like that, but you'd have to do some research to make sure first. I'm assuming the screen in that video is something like that, or at least has the capability to tune into those frequencies.
You can also buy an analog video receiver to USB converter that you can plug into a laptop or phone. I have one actually. When I plug it into my laptop, it shows up like USB webcam so I can watch/record it in the Windows Camera app. However, because it's converting an analog signal to digital, there is noticeable lag, so it's not really good to fly with (fine for a spectator though).
The benefits of goggles are the immersion, brightness, lack of glare, and stuff like that. Also, there's some industry standards around form factors and plugs, so you can upgrade the video receiver in the goggles if you want.

>>2803559
>>2803559
My analog feed looks like that too, but only intermittently depending on where the vtx and goggles are in relation to each other. I've tried all the usual suggestions to fix it, reroute wires, shielding, different antennas, change channels, fly in another location, nothing helps. When it's not doing that it looks very good, close to a digital feed.

>>2803559
>Why does the video feed look like this when using FPV goggles with a drone?
like what?

>>2803572
>However, all of those steps take A LOT more time to complete on both the tx and rx sides, hence the lag in digital video.
actually HDzero has lower latency than analog. especially when an analog cam has enabled WDR, essentially doubling the latency
DJI and Walksnail have higher than analog and it gets worse the more error correction they do because the goggles request a re-sending of the corrupted parts (two way communication)

>>2803585
mostly correct. analog broadcast was usually at 500-800MHz, although some countries even had channels down at around 80MHz
the FPV systems are usually at 5700-5900MHz, essentially mirroring what's allowed for outdoor wifi
some allow channels down to ~5400MHz and there are even TX/RX that use the 2.4GHz band as well as others that do 1-1.3GHz

>>2803592
>like what?
Old video.

Thanks for all the info.
I have another questions:

I need a controller to use the drone. Can it be a videogame controller (xbox, ps3, ps4...)?
If the answer is no what's the reason of that?
If the answer is not recomended but possible (usable) also tell me why.

Also for the googles i would use EV800DM i readed on this thread that you have to change the antennas my idea is tomorrow read the oscar liang guide to choose antenna.

I readed that i should use one omnidirectional antenna and a direct one at the same time is that true?

Any recomendation on specific models of antennas?

Thanks a lot anons.

>>2803644
>Can it be a videogame controller (xbox, ps3, ps4...)?
>If the answer is no what's the reason of that?
no because they don't have a way to communicate with the drone. A transmitter (controller) sends signals to the receiver on the drone. The receiver passes the signal to the flight controller that tells the drone how to move based on how you are moving your sticks.

If they’re not adjustable, you’re shit out of luck. Everybody’s head & eye spacing is different, most goggles have lateral adjustment to try to cover most users, but they will never suit everybody.

fucking around with the focus fixed it, i think my screens were focused at a short distance but i was supposed to focus them at infinity and have my eyes compensate which works flawlessly.

but now i opened up the goggles and went looking for misaligned optics and now they wont read the input voltage correctly. they always say it's 1.0V even if i put in 12V and they beep for low battery (but otherwise they work). i hope i didnt do any permeant damage maybe opening them back up and reconnecting everything again fixes it maybe its some ribbon connector that's not in all the way

Yeah there's a trick to it, you have to unfocus your eyes, like you were doing an autostereogram. Scroll down to viewing techniques, but the short of it is to "look beyond" the goggles, and focus your eyes as if you were looking at something 10ft away.
https://en.m.wikipedia.org/wiki/Autostereogram
Also I'm surprised that goggle manufacturers never mention this, but if you have a lazy eye you are SOL.

Someone redpill me on OpenIPC. What is it, video transmission using Wifi boards or something?
What is penetration and latency like, does it lag the fugg out when going around obstacles?
Can it reduce image quality when signal is bad, rather than just being a dumb video stream over wifi?

I'm still looking for a good analogue upgrade. Tried walksnail and hated the lagginess and hated how it fails (complete freeze rather than just about flyable snow as with analogue). Not gonna buy anything that requires online activation (i.e. DJI). Hdzero seemed kind of nice but I'm put off by the penetration apparently being worse than analogue.

>hated how it fails (complete freeze rather than just about flyable snow as with analogue)
im the guy you quoted and walksnail does not fail like that it kinda goes low-resolution and smeary.

openipc is firmware for security cameras (Internet Protocol Camera), specifically for their mass produced cheap chips like pic (the GOKE chip). in security cameras these chips encode the video and send it over ethernet. in the openipc fpv version these chips connect to a wifi adapter via 2 usb pins on the board and send the image via a protocol called wfb-ng (wifibroadcast-next generation) which allows you to use wifi chips as a digital radio to send arbitrary bytes to other receiving wifi chips (where's the regular wifi protocol requires maintaining a connection with handshakes and re-sending packets that were dropped which is not ideal in the FPV context where latency is more important than receiving every single sent packet)

its worse than walksnail in every regard (other than maybe being able to send higher resolution/FPV video) and the reason it exists is if you can use cheap mass produced IPC chips and WIFI chips you can drop the cost of digital FPV to be as low as analog FPV. i dont think it will ever match the penetration,latency,reliability of dji/walksnail but maybe a year or two from now it will be the go-to FPV video standard for most/beginners the way analog is now

Interesting thanks
The WS fail was when flying around a concrete building. There was a particular bad spot where analogue would have terrible static but would still be flyable. With WS it would freeze completely for about a second or two.
The impression I got was that with good to okay signal WS was likely superior, but when it got truly bad WS was unflyable in places where analogue would be.
Maybe I'll try it again sometime.

>>2804143
what power/antennas were you using in both cases?
i find this hard to believe i just switched one of my quads from 800mW analog to flying walksnail (goggles x + walksnail 1s kit) with stock LHCP antennas and it BTFOs analog easily even on 200mW (it goes up to 500mW i think) and when flying in bad RF conditions it does this thing where the sides of the image become blurred while the center is still fine which is i think partial retransmissions

>>2804143
Sounds like you're doing something wrong. 500mW WS has been getting me a clean image in places where analog 1200mW would have me blind. It's basically matching the performance of ELRS 2.4 in my situation.

>>2803236
Pic related was a certain community after someone used a Mini 3 from a car to check why there was a traffic jam.

Is 19000kv too low for 1s? (31mm props) I planned to use them for 2s but after my parts arrived and I saw how tiny they actually are, the extra torque for weight seems not remotely worth it.

>>2804854

It shouldn't have any problem flying on 1s but throttle mid may be higher than it would be with higher kv motors, so you may want to tune your throttle mid and exponent with that in mind. You may also find that you need to run 3+ blade props rather than the 2-blade props that are currently favored by the whoop community. The good news is that lower kv motors will generally be a bit more efficient.

my charger is rated like 500W but only has 2 ports ive been thinking i should get one of these splitters so can charge more without messing around with changing the battery being charged all the time.

but how do they work? wont it cause damag/problems if i connect one battery at 3.5 and one at 3.9 so the 3.5 one will get a sudden current spike which will degrade it over time?

>>2804961
Parallel charging depends upon your batteries being at similar voltages. One pack at 3.5 per cell & another at 3.9 per cell is more than I would do.

Parallel charging is great for charging packs that have all been stored to the same voltage, but it’s less useful if you’re just cycling packs that you fly to different levels of discharge.

>>2804966
i also have 2 discharge boards that can automatically very slowly drain a battery to 3.8 for when i plan to fly but end up cancelling for some reason. i guess i can parallel charge those easily since theyre the same voltage.

what voltage differences are acceptable for parallel charging?

ill probably just get another 2 channel charger , cheaper than getting s 4 channel one

>>2804982
nta, I've heard 0.05v difference is the max you want to go for safety. I've never used one thou

>>2804961
I use one. Even with a 50w charger and 6 batteries charging at only like 0.4c each it still saves time vs individually charging each one because im not switching them out.

Theres a few serious rules associated with parallel charging. You just have to be super careful. You'll need to do a little math and theres plenty of exposed contacts on those boards to accidentally short out all your batteries at once. Watch a few video tutorials, Im sure Bardwell has one.

>>2804961
I have two of these. They're great! Just be really careful of your XT30/60 plugs being crooked. I fried the traces right off the board on my last one with a crooked plug. As long as they're used right, they'll save you so much time!

>>2804987
The magic of parallel charging is that lower cells will absorb charge faster, so everything naturally auto balances. I've started them a whole 0.2V out of sync and they all finished in the same spot. As long as you don't go nuts with it, you'll probably never have an issue.

>>2805035
it does balance batteries but the moment you connect two that have a voltage difference that big remember that thaier resistance is very tiny so you're gonna have them charging the lowest voltage one at way over 1C and degrading the battery.

and if you have a beat up battery hitting it with a 5C+ charging speed is a highway to LIPO explotions

>>2805048
I've not seen so much as a spark or hint of warmth while plugging them in.

>>2804961
>if i connect one battery at 3.5 and one at 3.9
You should balance them out more closely if you can. If I had a battery where all my cells were at 3.9 but one was at 3.5 I'd be watching it closely.

>but how do they work?
Parallel chargers like that work by converting your smaller cell batteries into a larger cell, sorta.
If you have a 6s charger, you could plug in 6, 1s batteries and charge them all up at the same time. The charger thinks they're one big battery.

>>2805035
I'm to paranoid about battery health and fires to test this. maybe once I have a bunch of flight packs it'll be worth it.

BZ- is actually a switched ground, while BZ+ is a constant +5V. The buzzer is turned on & off by switching the ground, not the 5V.

So no, you cannot use BZ- as a regular ground.

Anon probably has one of the Matek MCU style buzzers that needs a constant power supply, hence why it needs an actual ground connection & not just BZ-/BZ+.

>>2805107
>>2805080
its a battery buzzer? the 5V-GND are used to charge the battery and when it tries to buzz the FC connects the BZ- to GND. BZ+ is usually just a generic +5V pad.

connect the buzzer to a +5V that turns on only when the battery is in and not one that gets powered via usb or you're gonna have it beeping every time you plug it in. you can use those USB powered +5V pads to let the GPS run and download the almanac for fast GPS locks before you go to fly.

True, however most people don't care. Hams won't come after you unless you're out causing lots of interference for them.

I'm building a miniature lathe and for that I thought drone BLDCs are perfect. Now the more I think about it the more I'm confused. I can't find any torque and exact RPM values of those motors on manufacturers website, I can't find anything about their temperature outputs and cooling as well as their maximum operating time, like can they handle 40 minutes of running without destroying themselves. I can sometimes find info about the bearings used but it's rare.

>>2806080
1/kv is the electrical constant ke of the motor, supply voltage * kv = maximum (no load) speed, supply current * ke = maximum torque
BLDCs really shouldn't be run straight from your house's 3 phase supply because they're not asynchronous motors and they're not rated to work at 310v

If you want to do this the right way you should get a VESC and a proper traction motor, one meant for a bike or e-skate

For reference an average 4s drone motor has 5mN at 30A

>>2806154

analog will be around for as long as digital comes with a significant weight penalty and other caveats. digital is still in relatively early days and there is no obvious "best" product.

)hdzero is targeted at a tiny market - people who want extremely low latency digital FPV and don't care about anything else at all. If this is you, you would already know that it was you. It's probably not you.

)DJI is excellent but proprietary in every sense and very, very heavy. A large segment of the drone community is focused on staying as small and as light as possible so I wouldn't suggest DJI as your first rig until you know you're not one of these.

)walksnail digital FPV is the most broadly recommendable digital setup at moment, but there is no particular reason to assume it will stay that way. IIRC the lightest walksnail rig comes at a ~7 gram penalty which is relevant for any multirotor with less than 5" props and for 5" builds targeting lowest possible weight.

)analog. lightweight, cheap, just works. visual fidelity is not as good as digital but that doesn't matter for most applications - if you want to shoot high quality video you are probably payloading an HD action camera or flying a not-FPV-drone with a gimballed camera.

This may have been true for the very first release, but the later versions have shaved a lot of weight.

Complete O3 system is 39g. That’s already small enough that you can put it in something like a Crux 3 & it flies really well. Proximity flying through branches in HD with a tiny quad like that is a big argument for visual fidelity of your FPV feed.

Fuck, that's more than I thought it weighed. I've got a Walksnail system at around 5g.

39g may as well be 39lbs in a field where the only relevant performance metric is disc loading. I'm not putting that on a quad literally ever.

You may lose sleep over individual grams when minmaxing your ultra lightweight builds, but the average person planning a 5” freestyle quad doesn’t even think twice about a 39g DJI FPV system versus a 20g analogue FPV system.

>>2806560
Analog slims down to less than 3 grams.

>>2806587
Nobody is using <3g setups on something like a 5” freestyle quad, where they actually want half decent camera quality, range, penetration, etc.

>>2806512
I have a hard time recommending anything at this moment. Analog is fine with me, but many take issue with the level of image quality. I like the Walksnail system, but right now their dedicated goggles are throwing a million red flags. Currently using their receiver module with a set of Sky04X goggles. DJI has always put me off with the price and locked down nature of their gear, plus I fly little stuff most of the time, and I'd rather not have the weight of a small brick. HDZero is really made for racers. It's fine for general purpose, but I hate the lack of penetration. That kills me because I like their treatment of customers.

But yeah, probably best to weigh your own decision. If Caddx would stop fucking up on their goggles, I'd probably recommend Walksnail.

>Any recent crashes?

You talk like a 658g 5” quad with a DJI O3 will fly *so* dreadfully compared to a 624g 5” quad with your 5g analog setup that nobody should even consider the former option, which is complete bullshit. Especially when you consider that many people opt for the DJI option specifically so they don’t have to carry a separate HD camera for decent footage - which then saves them substantially more than the 35g difference in the FPV systems.

If you want to minmax every single half gram off your builds, cool. But don’t go around telling potential newcomers to the hobby that they shouldn’t even consider DJI because it adds a few grams that they literally won’t ever notice.

does having a polarized antenna help with single quality?

>>2806650
An antenna is a radiator. Without it, the signal has nowhere left to go but back to the source. This can cause massive heating. Always have an antenna connected if that thing is on.

>>2806660
You're replying to multiple people. My argument has consistently been that an O3 is massive if you're doing anything smaller than a 5 incher. I've managed sub 100g on Walksnail and a 850mAh 2S pack before. Made for a great 3 inch cruiser that could do miles of range.

>>2806771
It actually does. When signals reflect, they create echoes that will be out of time with the desired signal. This causes you to interfere with yourself. By circularly polarizing, a reflection gets inverted to the opposite spiraling shape, getting partially rejected on the receiving antenna. Further, by transmitting a circular wave instead of a linear one, orientation doesn't matter nearly as much. A spiral doesn't look any different if you rotate it, but a line sure does.

>>2806771
>does having a polarized antenna help with single quality?

It helps when there are other people flying to have different polarizations on each aircraft. Also rejects a bit more noise and dramatically reduces "multipathing" especially when you lose line of sight when flying around a building or among trees. It's a noticeable upgrade and as long as you need a new antenna anyway, may as well go for it.

>>2806776
reflections will switch polarization no matter what kind it is (CP and LP)
two reflections and you're back at the original
but while a polarization mismatch has 20dB(?) penalty, a LP to CP will only have 3dB, no matter if it's vertical or horizontal
so in the end i think it's beneficial to have LP on the whoop/acro quad an CP on the RX
