In /rcg/ we discuss anything & everything radio controlled - multirotors, fixed wing, cars, rovers, helis, boats, submarines, battlebots, lawnmowers, etc.

>What about aerial photography, is DIY viable?

If you want a practical flying camera platform, DJI is the sensible option. If you want a fun DIY project instead & aren't too concerned about the practicalities, then by all means DIY something.

inb4 first time fixed wing flyers using gyro and autopilot complaining
>>
>>2132520
I used to work developing autopilot systems for copters and planes, so I have some background (seems like ages ago), I'm curious about how things have improved in the last few years and wanted to get back into it as a hobby using one of these as a baseline.

Honestly, just start with the bog standard F405-STD. It will run Betaflight, iNav & Ardupilot. It will do racing quads, big Arducopter hexacopters, it has a barometer for Arduplane, it has a micro SD slot for logging. It's just a great all round, solid, no nonsense FC that can be applied to all sorts of situations. You'll probably be pleasantly surprised what it will do for the money. You can also pair it with one of Matek's matching PDB boards for a really neat power wiring setup.

Does the Syma X5C controller use the bayang protocol? Does that mean I could use it with other drones and tiny whoops? I lost my Syma in a flyaway with an $8 joint taped to it last summer, wondering if I can use the controller with a Beta 65s lite or some other Bayang-protocol $30 whoop.

I think if you were to order something like this from a 'user friendly' online service like Armattan Productions, it probably would cost twice as much. But I order direct from a factory in China by just sending them an email.

There's loads of ads on AliExpress, made-in-china, even Instagram, for factories offering this sort of service. You just send them a message to start discussing what you want & what the price will be.

I even got a free cat in this order :3
>>
>>2135912
desu I think it's really cool that they do one-offs.

>>2135887
Also don't be afraid to shop around and use connections. I needed some metal discs for a reseach project last year. Got multiple quotes with about a 30% difference, then the professor told me to contact an ex-student at a firm the university sometimes does some free testing for and I ended up with a price that was less than half of the highest offer I got by asking for qutoes.
>>
>>2135913
>desu I think it's really cool that they do one-offs.

I imagine that with automated lay-up software it may even be beneficial for them to do some small one-off jobs like mine, to use up bits of sheets that might otherwise go to scrap?

If I wanted to build a dedicated long range cruiser, would I be better off with something bigger or smaller than a 5"?
>>
>>2136231
Do whatever you want, but a lot of people are going with 7" quads for long range. Personally, I think a wing is better suited to this kind of flying, but that's just preference.
>>
>>2136658
7" quads are a pain in the dick to tune aren't they?
>>
should i set my crossfire to 868 or 915?
>>
>>2136678
Depends what country you live in. US (& I think AUS) uses 915MHz, EU uses 868MHz. I don't know about Asia.
>>
>>2136231
Long range quads are a bit of a meme IMO. As >>2136658
hints at, quads aren't really designed for efficiently covering large distances. This is why when you watch Jordan Temkin's mountain diving videos, he's actually just flying a regular 5" setup - instead of flying for 5 minutes across boring open terrain before reaching the spot he actually wants to film, he just drives/hikes closer to the spot so his flights are only 1-2km.

>>2136659
This used to be the case back in ~2018, but these days they generally fly well enough for most people on stock settings.

I'm thinking about making a pic related, I've got no real worries about the structural side. Gonna be making the structural parts from carbon or glass fibre etc. but what about the electronics?
What sort of a control board do I need that can be programmed to change between "drone" mode and "airplane" mode at the flip of a switch on the controller? And what about autonomous flight, I'm aware of the process for making a simple autonomous airplane but could the ordinary methods be used for this thing too? Making it land and take off on its own etc.

>>2137873
single blade might be most effective, but they need a counterweight for balance which makes them shit
next one would be 2.7 blades, but well you know. 0.7 of a blade, you see...
in the end the compromise is 3 blades for being the most efficient
>>
>>2137973
>0.7 of a blade
Just shrink the other blades to the size of the 0.7 one
>>
>>2137978
if it were that easy you'd see them on wind turbines as those things are primarily built for efficiency
>>
>>2137983
But wind turbines are built like that.
It's a 2.7 blade prop where instead of making a blade smaller they distribute the lost surface area among all 3 blades, so it's nice and balanced.

I don't think Trappy is having a very good year. First Crossfire gets pwned on range and framerate by ExpressLRS, and now the v4 Source One frames are vibrating and delaminating because they're specced out with 4mm thick arms.

In hindsight, keeping the overall length the same as my quad frame but while shifting the front arms/FC back to maintain equal length for the arms, was probably a bit short-sighted - the front is more of an unsupported overhand than I'd anticipated. Probably reduce it by at least one 30.5 stack length for a v2.

I bought a 5 inch Apex frame like two years ago then lost my job, thinking about building it up now. It would be my first drone what are the flight times these days? More than 5 minutes now? Things are probably much cheaper now right? DJI affordable now?
>>
>>2138705
Ive been getting 6-7 minutes cruising/freestyle on my 5 inch lately.
Prices are actually up right now due to an international chip shortage.
>DJI affordable
HAHAHAHAHAHAHA
>>
>>2138705
Flight times haven't changed, there's been no revolutionary advances in battery tech. You're still going to get <2 minutes if you really abuse it, 8-10 minutes if you strap on a bigger than normal battery & take it slow.
>>
>>2138673
Those figures are really just what you'd expect for any protocol operating at those power levels on those frequencies.
>>
>>2138736
Not that guy but what about aircraft? I want something that could do ~30 minutes of flight time, is that possible?
It doesn't have to be fast or pretty, it just has to stay in the air for that long with a small camera as payload.
>>
>>2138764
Fixed wing (planes) are completely different to multirotors. Achieving 45-60 minutes with a plane is utterly trivial. However you have to remember that they fly completely differently - you can't hover in one place with a plane, you can't take off/land vertically from a small area, etc. Obviously you can build VTOL 'quadplanes's etc. but I'm trying to generalise here.
>>
I don't own a drone, but I have a Turnigy Evolution. I was trying to use it for the simulation game Liftoff. It is really hard to control the game. At first I thought I was just bad at using the controls, but now I think something is just wrong. Any suggestions?
>>
>>2138764
The DJI drone I saw at Costco today has a flight time of 30 minutes for $430. I know that’s not a racing drone but damn why aren’t we even close?
>>
>>2139001
We are pretty close to that actually, with stuff that you would use like a DJI. There are actually some maximum efficiency long range cruisers that can get I think its like 55 minutes.
>>
I can't wait to get my Fatsharks so I can get rid of my shitty box goggles.

>>2139007
Its better than analog but nowhere near DJI, yet.
>>
>>2139012
Have you used it or are you just going off what Youtubers say?
>>
>>2139001
The original post that was responding to was talking about a regular 5" freestyle quad (Apex). Of course you can DIY something like the DaveC Micro Long Range which will fly in a similar fashion & for a similar length of time to a DJI Mini 2, but that's a completely different thing to a 5" freesytle quad.

>>2139007
>I'm planning to eventually get it but I don't have the money right now.
I'm gonna get it when they release some nicely integrated goggles rather than the current frankenstein thing

>better than analog
I prefer analog, simply because in strong interference I can still make out shit to avoid and which way to go.
>>
>>2138862
>>2139175
I think there is something wrong with the controller/receiver. I don't know how to troubleshoot without a real drone.
>>
>>2139378
You just suck at controlling the drone. Drones are hard to fly at first. You have to practice for a while. I just started last week and i thought there was something wrong with my controller too.
>>
>>2139378
Whats it doing that you think something is wrong?

Why can't this stuff be more popular? It's so awesome. If your average person got a chance to experience it, then they'd be hooked.
>>
>>2139636
Your average person is too dumb to make it through the firmware-software-serial port configuration hell and come out the other side. It's still like the internet in the 90's; there is a minimum IQ required (and that's probably a good thing).
>>
>>2139962
This is exactly what the DJI FPV quad does. It makes it easy enough for pretty much anybody to do, but also retains some of the DJI geofencing stuff to try to prevent the worst of people flying in dumb places.
>>
>>2139971
With the goggles/controller the dji drone can be had for the reasonable price of 1300 dollars. Which basically makes this a toy for people who are well off. If you're already into FPV and have a DJI headset then why would you ever buy the DJI drone. It's a beginner drone that costs a ton of money.
>>
>>2139979
Yeah, for the $740 that the DJI FPV drone costs, you could buy 3-4 decent analog drones, or a couple of digital drones, plus pay much, much less for replacement parts after you crash the shit out of them while actually having fun. The DJI drone just seems like having sex with an expensive (yet slightly weird looking in an almost hot way) whore while wearing an extra thick condom.
>>
>>2139982
This is the case with everything though - accessibility costs money, especially fairly complex things which require more than just a precursory understanding gleaned from watching a 3 minute YouTube video.
>>
>>2139994
The good thing about the drone hobby is that the learning and cost curves are very gentle, you can start with something really cheap and easy to fly; some 15$ toy drone you can fly, crash and fly again, or even a full all-in-one FPV one, like the E013, if you dig it you can then get a cheap Jumper multiprotocol radio you can use your existing drone with, then a cheap small programmable 3D drone...
>>
>>2140005
Absolutely, but for every person who reads that sort of solid advice, there is another who unfortunately watches a clickbait YouTube video ($99 RACING DRONE!!!) & ends up having a really bad time when they discover a week later that they can't get their 5" quad built because they've literally never soldered anything before in their life.

My experience with Liftoff was pretty bad. Even after 5+ hours I could barely control the drone in game. I bought a tinywhoop anyways and was flying it pretty well within 5 minutes. Sims are overrated.

Most people fly Whoops in angle/self-level mode, but use sims to learn how to fly rate/acro mode.

Has anyone ever had a lipo battery explode on them? I'm kind of paranoid that one will explode while I'm sleeping. Not that I charge them while I'm asleep.
>>
>>2140594
I charge mine while I sleep, Ive accidentally shorted balance and XT60 leads before, Ive charged my batteries hot and freezing, Ive even just last week witnessed a friend charge a battery and could actually see it puffing up as it got too hot to touch. He yanked it off the charger and threw it into the lot infront of his house, nothing happened.

Im not gonna tell you to get careless, lipos going up in smoke is fairly common. Thing is it usually doesnt happen spontaneously. You have to puncture a cell, overcharge it, charge it at too high C rating, or something similar to actually set one off.
>>

I just got my Fat Shark Attitude V6 goggles in the mail. I don't get what's so good about these. I guess it's better than box goggles but not by much. I thought these smaller goggles were supposed to be a huge jump over box goggles. It's just 2 little screens instead of one big screen.

The real benefit of FatSharks is size & weight.

Yes, there have probably been many bug fixes/stability improvements since 2019. You may not have run into any problems yet, but it's an easy upgrade for peace of mind.

I want to get into fixed wing fpv and bought a zohd dart250 around 2 months ago.
Now the only thing that's missing is the transmitter and banggood just changed the order status back to processing

I just want to fly

Good now buy a drone.

>>2142456
Just hit up the local forums and buy a used Hitec Aurora or a Futaba T10, you'll be better off in the long run, especially with fixed wings.
The OpenTX is a bitch to set up properly for some more complicated planes where you have to mix for different modes or just having an aileron differential
I had all of them, Turnigy 9X, FrSky, ended up with Hitec (and sold my Futaba FF9 with rampac), setting up my gliders is a breeze and setting up flight conditions for the quads is easy as well.
>>
>>2142474
REALLY bad advice here, recommending Futaba of all things, what the fuck man?
>>
>>2142477
Having quite some years of experience in RC with both fixed wings and helis, later multicopters.
OpenTX is inherently shit for fixed wings. Have you tried setting up different butterfly mixing with thermal settings on OpenTX? Takes the whole day to finally dial it in while on Futaba and Hitec you have the option right there in the menu. It will also set it up for you according to your wing settings and that is on the ages old FF9.
The RC world is not just about the newest "drones", zoomer

>>2142784
The usual problem with that sort of 'boomer' is that their experience only goes as far as 2003. Visiting my local flying club is like stepping back in time & it's not even a case of 'the old ways are better' - so much of it is just making their lives objectively worse.

I'm seriously asking, how much experience do you have in F5J and especially F3J competition flying?
When you get a $1000+ (and more like $2000-2500 today) model that has the potential to kill in one way or another, you will definitely think about what system you are trusting your full control. And I mean full control, some minor glitch means going out of control and these things do not bounce back like your average foam flyer, they will pierce a man without any major loss of energy. Or mince up in the case of a motored plane, anything above 2m wingspan is fucking lethal.
There is a very, very good reason why the "old boomers" at your local club behave like they do and huff and puff over your cheap chinkshit radios. I mean there were deaths during pulling up a fucking glider, in my country there is no public RC events held since 2006 when a scale model turned a couple into pink mist right in front of their child. Cause: radio interference. It was on the old analog 40Hz but it shows how much you need to trust a system, and you buy the best not because it is expensive and you want to show off, it's because you don't want to hurt innocent bystanders. Not losing a model is the icing on the cake.
There is a good reason why Spektrum and DSM/DSM2 systems were looked down upon, those were known to brown out from a slight extra load on a servo.
You buy the better system to trust the clean and strong signal and resilient RX, you buy the good quality servos so they don't burn out your entire power supply, you buy the good ESCs and motors so they don't make your plane into a flying deathtrap from shorting out.
There is a good fucking reason why any seasoned RC modeler will ditch the chinkshit in favor of the good stuff.

>>
>>2142837
Agreed. It's a pain in the ass.
Example: setting up a low batt alarm. It should have that feature put of the box, instead you have to fuck around with virtual switches and if statements and selecting the correct beep or sfx (for which there is no audio preview)
I get that it's probably powerful but my shitty flysky tx had this working out of the box. And everything else was a lot easier to configure too.
>>
>>2142943
On my Hitec I just push the battery icon and set the alarm. Every setting I would need is there in a conveniant way, don't have to do a whole programming course to set up elevators and flaps with relations, it is right there in the menu.

I'm having to put in new everything, since I have an empty hull after using it for parts for 2 other identical boats
Stock setup is a combined brushed ESC and receiver, 540 motor (heard it was 21 turns) and a 7.2v 1500mah lipo.

Wanted to go brushless and 60 amp ESCs seem like a really common paring for the brushless motors that would be a direct fit where the 540 brushed was.

You might want to put a copper tube in U shape over the heatsink with heatpaste and shrinwrap it back, normal ESCs rely on a constant fresh airsteam to keep cool, in a boat there is none, same for the motor if it is not an outrunner. You will have to put in a water line from the stern (usually the rudder has a hole for intake)

As somebody who owns that exact setup (which I had to pay substantially more for because >UK), I can tell you that you absolutely do not need to spend that much.

If you're not actually flying at any sort of range, then two decent omnis mounted in different orientations is the best option. I like the Lumenier ones because they're just so small I can leave them on my goggles & not have to worry about breaking them when I throw them in my bag.

For longer range I swap one omni out for a TrueRC crosshair/X-AIR, which is the first directional antenna I've used that actually makes a difference. All of the cheap little PCB patch antennas I used previously were no better than just leaving the second omni on.

Decent brands are TrueRC, VAS, Lumenier for AXIIs, literally any brand is fine for Pagodas, Foxeer is a good budget option for their lollipops.

Foxeer lollipop or Lumenier Axii 2 for Omni, paired with a patch antenna as big as you are comfortable wearing. Also keep in mind that more dB of gain means a more narrow beam width, which will be a different shape depending on what kind of antenna it is. Your head can block some signal too, so try to keep your head where the signal is weak (along axis of Omni and dipole antennas, and on a plane out the sides of a patch antenna).
I just run a 2" omni with a 90 degree elbow on the top SMA, and a patch on the bottom with a 30 degree elbow rotated so the patch points about 15-20 degrees up, but also 15-20 degrees to the right so I can get some unobstructed signal out the back.
Pic related is another option, each omni covers the others dead spot.
>>
>>2144490
Oh, it felt like it, but with 3 axis hexas I always feel like they won't take off. Will you try beefier motors/props later?
>>
>>2144894
Also note that any decent normal patch (circular polarized) will have 90° to 60° angle of beam, so direct it the longer axis of your flight while the omni will allow you to go wide and behind you
I use the Menace Pico and the original Fatshark omni, this gives a decent amount of distance between the two antennas.
>>

Who knows, maybe one day. I have less money to spend on this stuff now because of a forced job change due to COVID, so it will probably stay like this for a good while.

Got trolled hard by Ardupilot today. Apparently there are certain conditions in which the 'landing detection' doesn't work & the copter will think it's still airborne even when it's landed. It then interprets the disarm stick command as an actual yaw command... so promptly shoots up & flips over.

If you fly in a place with people that's on you. RC models are very easy to crash, good electronics just save you from electronic failure. Anything can happen, from parts coming loose to sudden gusts of wind pushing your shit around or simple pilot error. Number one rule is that if you're flying you should be prepared to crash, because shit happens. This is why you boomers have RC clubs in the middle of bumfuck nowhere with a nice long airstrip and tons of empty field all around. Like this you make sure the only people around that could get hurt would be you and your fellow pilots, and you're all bunched up in one spot to minimize the chances of a plane coming right at you. Again, if you fly in a public space with people all around that's on you, stop being retarded.
Also flying chinkshit is fine, not everyone wants/can drop hundreds on expensive shit to throw in a small trainer. That's just gatekeeping the hobby.

How much do you know about F3J championship flying? I mean the proper FAI rules.
You pull by hand through a pulley, two people side by side. This rule was made because the pulley is tied to the ground by a couple of big long nails, big and pointy nails. You can pull it up by yourself and at a time it was the norm until the nails dislodged and hit a kid in the back with the pointy end. At the height of tension there is about 80kg load on the line with the carbon gliders. Needless to say the nail stabbed the kid to death. It happened in eastern Europe, don't know if Slovakia, Czech Rep or Poland but the champion at the time resigned and never touched models again.
The other thing, the motor plane incident happened in Hungary, in Őcsény. I don't know if there are articles in english but that one was well documented because of the huge normie crowd, cameras, news reporters etc...

Can someone enlighten me as to why you would an X2212 motor over an R2306 motor for a wing/plane? (Wing designated motor vs quad drone race motor)

The X motor is like 30g heavier and handles less power and has higher resistance. If there is a bug kV difference you can use a motor throttle limit to overcome that.

The X motor has much higher thrust to power ratio, but that’s because the test data is with bigger biprops while R motor data is with 5x4 props. So that efficiency advantage is just from the prop.

t. 2800kV motor on a wing I just don’t have a current sensor installed to see what it uses at specific speeds.

Point to one design principal that makes Hitec/Futaba more reliable and "safe" than any offerings supporting openTX.

Then point to one way any openTX offering is inherently prone to failure.

If your response is something along the lines of "they just are" or "boomerBrand (TM) is tried and true whereas we don't know about these others / I saw a failure myself"
Then you're full of shit and have no fucking clue what you're talking about.

It sounds like you're comparing one of the ancient black SunnySky X2212 motors against a modern 2306? Lots of manufacturers still ship models with these obsolete 1st/2nd gen black motors because they're cheap (lots of factories still produce fakes), not because they're actually best suited for the job.

A better comparison would be something like the current generation SunnySky X2212 (>>2145304) which is a completely different motor & will handle larger props (8-10") a lot better than a 2306 even if you try to match rpm with throttle limits/reduced cell count etc.

Quality control
>>
>>2145817
Now compare the number of incidents caused by 'poor quality control' in Chinese radios, to the number of incidents caused by using obsolete air protocols with Hitec/Futaba radios.

I would take a modern cheap FrSky ACCESS radio & a model with a FC+GPS over an ancient expensive Hitec/Futaba radio & a model with no proper failsafe handling any day.
>>
>>2145821
In my own experience, 5.
One FrSky having a shitty soldering on the antenna.
One OrangeRX crapping out mid flight and not coming back on. There was no overvoltage (servos would've died too) no shorting, it just died.
One HobbyKing branded RX crapping out randomly, no visible signs, turned out to have massively reduced range while everything seemed okay.
One other Hobbyking branded RX having reduced range as well on ground test so at least the plane survived
One Turnigy radio having the mainboard crap out midflight, memory failed so lost all models, then just died completely. Battery was not connected the wrong way
All of these were from friends asking to maiden or help in some way with their planes.
Oh, one more, 6th, one other FrSky radio having reduced range but still flyable although gliders always gave RSSI alarms and choppy controls. This was mine and pushed me over to buy a beat up Futaba FF9 then later on the Hitec Aurora I'm still using to this day.
And for those budget minded there are plenty of multiprotocol receivers on the market (OrangeRX, FrSky Delta8 etc...) although I always go with first party on my "big" models
>>
>>2145824
Oh, and with comparison on "big name" brand radios in my local group, and adding the nearby groups as well, there were no radio or receiver related incidents. None up to this point from when I started.
Also note nobody is flying with Spektrum.
>>
>>2145824
>And for those budget minded there are plenty of multiprotocol receivers on the market (OrangeRX, FrSky Delta8 etc...)

This really just emphasizes how out of touch you are.

FrSky D8 is a completely obsolete protocol which has been officially discontinued for years and for good reason - newer protocols are quite simply, objectively, better and safer. Ideally nobody should still be using D8 gear in 2021, but definitely nobody should be recommending others to buy D8 gear in 2021. Iirc Frsky haven't sold any D8 products since ~2016.

And OrangeRX? That's Spektrum, isn't it? Friends don't let friends use Spektrum - the air protocol is garbage and proven to be highly insecure/easily exploited.

I'm happy that you've had such good experiences with your outdated equipment, I'm sorry you've gotten unlucky with QC on newer gear. But please fuck off if you're going to continue telling newbies in these threads to buy Hitec instead of a Radiomaster. Nobody needs their first introduction to the hobby to be struggling with an overpriced antique which they can't find any help for online or with local groups, because the only people who still push this crap are retirees.
>>
>>2145833
Oh and for the record, I've never had any QC issues with any of my FrSky gear, nor have any of my friends who also fly FrSky, so that just goes to show how much our isolated experiences are actually worth in the grand scheme of things.

Incidentally, one of the people I fly with is in his 70s, has flown all his life, but left the local boomer club to join our group specifically because of people like you there who obstinately opposed progress and made the club so hostile to newcomers.

Quality control is not a design principal.

And newer futabas and Hitec have similar low quantity issues.

OrangeRX/TX/ hobbyking are also not openTX.
Turnigy supports openTX, but only the 9xrPro officially.


>lol look up non existent stats
your argument is literally "in my experience"
you don't know what you're on about.

The chips are the same, and the software is solid. Protocol and RF are the weak links, which the newer protocols solve.

One thing you'd learn quickly if you knew anything about electronics is that, like their data type, digital systems rarely fail in a way that could cause a crash without obvious signs before takeoff; They're usually binary, working or not working.
Everything else is probably your own fault for not doing the preflight you boomers insist be done by the "AMA Site safety faggot" or something like that.

The other non-binary issue is RF, but you did do the range test, right? you know, the one even Futaba says to do?

>One Turnigy radio having the mainboard crap out midflight, memory failed so lost all models, then just died completely. Battery was not connected the wrong way

you either did install it wrong and won't admit, or did a quick and dirty openTX installation.

>One other Hobbyking branded RX having reduced range as well on ground test so at least the plane survived

did you try steps to mitigate RF interference/shitty antenna placement?
even spread spectrum 2.4 can get clogged if lots of dudes are flying

>One OrangeRX crapping out mid flight and not coming back on. There was no overvoltage (servos would've died too) no shorting, it just died.

Overcurrent, plus shitty antenna placement. You can do both to boomerBrands too.

You realise that quality control applies to protocol development too, right? That your decades old Futaba/Hitec air protocols are objectively absolute garbage 'quality' compared to modern alternatives that handle self-healing, encryption, spectrum hopping etc. infinitely better?

It doesn't matter if your radio uses ICs hand picked out of millions to ensure the highest quality and tightest tolerances, if the protocol you're actually beaming out of them into the sky is shite.

Yeah, but even if I look at that, the max power to weight ratio of the motor is still much poorer, and doesn’t appear to more efficient than a 2306 sunnysky. Wondering what am I missing here. They’re also both around the same price too.

There is also the 2308 2000oV, harder to find, I could just go to another brand for a slightly larger fpv quad motor with the same results - saving a fair bit of weight on the motor at one end of the plane which could affect CG design quite a bit.

Looking to build my first RC car but not sure what battery to buy.
I saw someone saying that the cheap chink batteries have awful voltage drops under load.
What do I need to look for to avoid that?
>>
>>2146614
Buy some quality 18650 cells and use those. You're not constrained by weight the same way you are in a drone or plane so it's a viable option.
>>
>>2146614
Where are you buying the car from? You just have to get reputable batteries, not no name ones, but that's basically impossible for beginners. Most of the batteries on Hobbyking are ok, but if you're ordering from somewhere else, you can probably get good batteries from the same store.
>>
>>2146579
Stator size & kv essentially dictates the size of prop & the number of cells that a motor will work properly with.

Something like a 2306 2400kv motor is intended for 5" 4S.

Something like a 2308 2000kv motor is intended for 6-7" 4S.

Something like a 2212 1250kv motor is intended for 7-10" 4S.

If you try to fly your plane with an 8" prop on a 2306/2400 & a 4S battery, it's just going to catch fire.

>>2146614
Don't buy batteries from China. Even if they're not crap, the chances that the delivery will get blocked is too high to be worth the risk.

That's not how it works.
>>
>>2146839
You will be at substantial risk of burning out either the ESC or the motor. This is how power works.
>>
>>2146868
>You will be at substantial risk of burning out either the ESC or the motor
That's a long way from plane catching fire.
And if that's the issue then don't jam the throttle to full like an idiot. With a bigger prop you can max out the motor's power easily so there's no need to go full.
>>
>>2146877
Somebody who is asking such basic questions about motor/prop choice most definitely should not be expected to be able to govern their throttle use to safe limits when massively over proping a motor like that.
>>
>>2146672
>>2146868

That’s not how it works. Motor output limit will limit yhe max throttle. You do not need to fly it at 100%. Flying a 2400kv motor at 50% is like flying at 1200kv motor at 50%.

Additionally the 2306 can handle /more/ power than the X2212, which means it’s capable of more torque. The motor doesn’t know what prop is on it.

And larger props require LESS torque to fly than smaller props - larger props are more efficient and will use LESS power for the same amount of thrust, meaning LESS torque for the same amount of thrust. Eg we might want 300g of thrust for cruising. An 9x6 biprop will use less power to do that than a 5x4.5x3 etc.

I already fly a wing with a 2305 2800kv on 6” with 4s with this and it works well.

There is no reason you have or need to run 5e motor at 100%.

>>2146883
You’re too much of an idiot to actually read and comprehend. >>2145497
>you can use a motor throttle limit to overcome that

>>2146969
The person who actually asked the question is a newbie. The correct answer to their question is simply that a 2212 motor is designed for a larger prop than a 2306 motor. The reason their particular comparison seems to go against that rule, as already explained, is simply that the particular 2212 motor they are looking at is an antique.

Stop confusing newbies by nit-picking details when the question asked for a generalisation. Bigger motor, bigger prop. Smaller motor, smaller prop.

>>2147128
I asked the question, and the X2212 V3 is not an antique. The 2306 produces more power (thus more torque, throwing the torque argument out the window), and produces less heat.

The “designed for prop size” is a meme and literally not a valid answer. The motor doesn’t care what prop size is on, the only thigh the motor does is spin against a resistive load.

If you go by that a larger prop is more efficient for the same flying speed and load etc, then it follows that a larger prop required /less/ torque than a smaller one as it requires less power (more efficient).

It is not a generalisation, it just escapes your grasp. There does not seem to be a valid reason to pick a “wing” motor in this instance over a quad motor when you adjust for kV differences via a motor output limit.

You then have 30 grams less weight potentially right on the nose, which can impact CG, and wing load. You can produce less heat in the motor and possibly more efficiency due to that.

Unless there is something else being overlooked that the 30g heavier motor has an advantage in then everything is covered and points towards the quad motor performing better.

If you don’t know then stop pretending to know, what you have “answered” is meaningless. Even in the original post I mention using a motor output limit.
>>
>>2147178
It looks like are confusing mechanical power with electrical power and that you don't actually understand how torque works with regards to brushless motors.

Have a read -

https://www.rcbenchmark.com/blogs/articles/brushless-motor-power-and-efficiency-analysis

And nobody is talking about 'wing motors' vs 'multirotor motors', a motor is a motor. I'm talking about larger stator volume/lower kv vs smaller stator volume/higher kv.

By all means fly your wing with a massively overpropped motor with a throttle limit if you think that's best. But please stop trying to 'prove' that it's actually better until you understand the basic science behind your arguments.
