can i do this to run my jumper t lite v2 ELRS radio at say 250mW/500mW instead of it's capped default 100mW?

when i go into the internal module's wifi configuration page i see these power values. im assuming these are the values for 10mW,25mW,50mW,100mW since those are the options in the LUA script on the radio.

does anyone know how i can get 250mw,500mw and so on? i dont want to set it to something insane and ruin it by mistake and i dont really have a way to accurately measure the RF power

No. Please stay away from airports and crowded cities with your flying camera.

just build whatever the tinywhoop tubers are using today.

>>2774880
idk about ever been made there's probably smaller prototypes
but the lighest one commercially sold is probably the mobula 6 2024. its like 17 grams (~26 grams with battery) and its overall diameter is like 96mm.
i dont have that one but i have the mobeetle 6 which is somewhat similar

I was considering those two, would it be worth going for the boxer despite it being x2 the price of the pocket?
I have quite large hands so the extra size would be nice, and the boxer being able to take nearly any 2s lipo that'll fit inside it would save me a few bucks as I already have a few 750mah, 1600mah, and 2200mah packs from my RC car shit.
I don't mind spending more if it's really worth it in the end, especially on a peripheral.
>>
>>2775113
Get the boxer, it's made for anons in your position
>>
>>2774984
get a radiomaster pocket its cheap,small,takes 2 batteries and you can easily upgrade it with the strongest transmitters like the radiomaster ranger that supports ~2w

its what id get if i was buying today and i got the jumper t lite at the time. the only reason to get anything more is if you hate gamepad style controllers or need a touchscreen/a billion switches
>>

i copied the settings (power values and power mW) from a 500mW TX module into my internal TX moule thats limited to 100mW by default.

i dont have the tools for rigorous testing but when connected to my drone on the desk i got a nice 3-6 db jump each time (keeping position of drone and controller and the environment constant) i increased the power on my controller so it might be working.
>>
Another pocket owner chiming in.
I have small hands and I don't really like the form factor, the smallness of the gimbals, or the cheapness of the switches. If you're on the fence between the boxer and the pocket I think the boxer is a much better choice.

flew my OpewnIPC quad today, fixed an issue with the mavlink telemetry to the camera by twisting the data cable so i had data on my OSD unlike last time.

i still have no idea how to record video from the main camera, i might just use an HDMI splitter + capture card connected to my phone or something. the openIPC AIO supposedly just has an sdcard slot on board for recordings.

Bought a jumper tlite v2 from aliexpress, shit straight up doesn't wanna turn on a lot of the times randomly, I try to charge it but it stays on the same battery level, and other issues related to staying on, fuck I made a mistake buying this. I feel like the battery is loose in the back and when I move the controller it loses the connection to it something fuck this thing
>>
>>2775935
Ok I bended the contact tabs a little bit and the battery holds better and it seems to be more consistently powering on, I'm stupid lol
>>
>>2775941
you can also put a sheet of some thing foam against the battery lid
so when you close it there will always be a little pressure on the battery, keeping it in place
>>
>>2775935

are you sure you are using an 18650?
>>
>>2775963
>>2775982
the bending of the tab solved all issues and it works great now, it expects the 18650 battery to have a protruding nob or whatever you wanna call on the positive side and mine doesn't that's why it was falling out

anyway's I've been flying for the past few hours in velocidrone and I'm having tons of fun, I wanna buy a real drone and goggles now lul
>>
It rained today. Goddammit. I was hoping to get some more practice with my meteor65. Not quite confident enough to fly it indoors, I've been eating too many weeds.
>>
>>2775935
ive had problems with it too the metallic battery contacts are too loose, try to bend them so they apply pressure on the battery and it sits tightly in the controller.
i think they were created with non flat 18650 batteries in mind so that the common flat ones are too short.

>>2776065
thats totally an indoor quad, also basically indistructible unless you really slam it into things full-force and even then its just a broken prop at most. if you're new to quad flying connect your controller to your pc and try fpv simulators on steam until you can do basic flight stuff like staying level,flying forward.
also by default the camera on the meteor points up, you want it as low/flat as possible when learning/for slow and level flight.

Fuck, I can't find one specific EU hobby store anymore. Was located somewhere in Czech, Hungary or Poland I think. Sells XT connectors and servo wire in bulk under their own brand.

Also I can recommend Volantex stuff, very pleasant to fly.

I've done regular wings, but never something completely finless like a Prandtl. I'd have to think it's very difficult to find the right self-stabilizing airfoil without introducing problems like dutch roll.

i set it up as a vrx but i dont have time to go test it right now.

im thinking if i have a whole ass computer as a VRX i could try to take the mavlink telemetry from the video wifi link and use it to drive an antenna tracker like a myflydream crossbow mini from the computer's uart pins.

i think the better alternative to this would be using the telemetry from my elrs radio controller to drive it tho but its less obvious on how to do this

i started testing more stuff at home before going out to fly after this shit happened too many times. usually for me its some loose PH connector or electronic interference.
twisting your wires does wonders to fix the latter i had GPS that wouldnt lock, telemetry wires that would only transmit telemetry like once or twice a minute and shit like that.

im thinking of buying shielded wire for all my connectors like those 2/4/6 core 28awg wires that have aluminum foil and a copper braid around the wires

Interference can cause a failsafe, but it can’t cause the receiver to unbind.

There is apparently some plan in the works to output basic telemetry via ELRS backpack at some point. I've been waiting to get my hands on it for that exact purpose.

i just got my crossbow mini in the mail.

if you have an edgetx radio with a usb port it has a mode called 'telemetry mirror' where the moment you get a serial connection (like what you use to flash edgetx) it starts sending over it's telemetry.
you can connect your phone to the radio via usb and use this
https://play.google.com/store/apps/details?id=crazydude.com.telemetry
to view this telemetry on your phone.

idk what protocol this telemetry is (i think mavlink?) but my idea was to convert it to mavlink via some kind of a python script running on a small computer. and send the mavlink via uart to the antenna tracker. i think the antenna tracker just waits for the mavlink packet with the gps,altitude in it and points to it the moment it gets it.

if however my video system also transmits mavlink telemetry (to draw all the stuff on the OSD like speed,altitude,battery voltage) and its just a radxa 3w computer running debian i can just run a script on it to also send the mavlink to the computer's GPIO UART pins and to the antenna tracker.

idk ill fuck around with this, my goal is to have an antenna tracker i can slap on the roof of my car (magnetically held) and fly long distances with. the tracker is 350grams so i can easily hold it to the roof with a couple of strong N52 magnets (id need to test if it doesnt fuck up it's compass).

the radio outputs CRSF over the USB
https://github.com/crsf-wg/crsf/wiki/Python-Parser
ive run this python code on my pc connected to my jumper radio and i see the GPS from the drone that ive powered and put outside my window.

i think i can get some old raspberry pi zero i have laying around to take this data from USB SERIAL to the uart pins on the raspberry and into the antenna tracker since it supports crossfire as show in this vid
https://youtu.be/ZpC2FIxehF0?t=362

i dont get why they dont sell this as a feature on an antenna tracker to connect to your radio with usb and use that to track the drone. i guess ill have to put in some kind of sbc just to translate usb serial to uart
>>
>>2777323
i did the same shit i connected a 5v VTX to an FC that uses 9V for its vtx pins be default. but it worked afterwards, didnt get fried theres probably protection.

it was the speedybee tx800 , speedybee stuff is very reliable vs other companies in my somewhat limited experience (had a mateksys and a diatone FC/ESC stop working chile my speedybee one keeps chugging along)

These pads set what voltage comes out of the +vtx pad.

Right now you have the middle pad connected to the 10V pad, just like in picrelated. So the output from the +vtx pad is 10V.

If you remove that solder blob & make a new one that connects the middle pad to the 5V pad instead, then the +vtx pad will output 5V.

If you saw smoke, then the vtx is most likely dead. But if you get a new one, double check what voltage it needs & then double check you set it correctly before plugging in.
>>
>>2777372
oh you mean how to switch it to 5v?
carefully touch the connection between the vtx+ pad and the 10v pad with a hot soldering iron and the solder should get on your iron and disconnect the connection. then carefully put solder between the vtx+ pad and the +5v pad
>>
>>2777376
>this is why you read the manual\wiring diagram of the FC before using it.
but i did, was i supposed to resolder this?

>>2777378
i guess i'm learning the hard way again.
>>
>>2777380
yes
looking at it again they should have put a bigger warning on it. or even easier to just provide separate pads for 5v 9v 12v instead of that jumper thing.

i dont get why they do this shit of putting 9v/12v as the default. most VTXs i see are 5v and 5v wont risk frying a 9v vtx wheres the opposite isnt true.

its a major design flaw
>>
>>2777382
I’ve never seen a flight controller like this come with the selector pre-soldered.

speedybee f405wing has it set to 9v by default, but there having a bridge makes sense because it actually has a ph connector for the vtx.

on quad FCs where you just have solder pads they should just give you 5v,9v,12v pads instead of a bridge thing to select voltage

mateksys h743 slim has a selector but its all desoldered by default so you cant fry your vtx by mistake. thats how they should do it
>>
>>2777406
But you need a bridge to actually set the output of the regulator itself. Otherwise for 3 separate pads for 5/9/12 you would need 3 separate regulators.
>>
>>2777424
i thought they had multiple regulators you just bridged them to the other vtx power pad

ill check if i get 12v on the 12v pad on my speedybee when its not connected but yea you're probably right
>>
>>2777425
It’s a single regulator where the output voltage is controlled by a voltage divider on a reference pin. The little selector pads where you bridge one way or the other physically selects what resistor makes up one half of that voltage divider, thus toggling the output voltage of the regulator.

You know the Daleks were made mostly from household things. Read up on what was used to make the Daleks, that should a be a start. For anything geometric, I would make a frame out of wood and then put thin wood panels over the frame. I am an aircraft guy, so my go to wood is balsa, but I think birch might be better in your case.

>>2777287
I wasn't aware of this method. That's great! Gonna have to dig into that topic again and see what I can learn. An antenna tracker is something every distance flyer should have. Almost lost my first quad on my first long range flight because I did a shit job of tracking with my patch antenna.

My saga continues.
I resoldered the horrible soldering job on the DJI wires and removed the yellow and grey wires from the board + cleaned up the excess solder and shorted the connections.
I am not good at this so it's still not great but it's better.

Betaflight still does not recognize my receiver in IBUS mode (RX1 pad) but when I switch to SBUS it recognizes that it's there, but it can't take any input from my radio...because it's an IBUS receiver.
I am beginning to think that this FC just doesn't work with IBUS at all. The manual doesn't mention it, anyway.
Anyone want to recommend an SBUS receiver?
>>
>>2777368
Odd, I've seen the opposite. I wanna like Speedybee, but they keep ending up with dead shit all the time. There were all the F405 V3 boards with issues, my buddy had that same VTX blasting a ton of noise and wouldn't change channels, and there were all the ESCs popping components.

Like I said, I really do wanna like them, but they have a lot of reputation repair to do for many.
>>
>>2777382
Most VTXs I see take between 7-30V (yes, the whole range), as for breaking out the pads, I think these 5 or 10 pads are just putting two 5V regs in series to produce 10V. It's more versatile, cheaper, and space saving that way. It's good practice to put a meter on your voltage pads prior to using them. Takes mere seconds.
>>
>>2777648
the only problem ive ever had with a speedybee component is the f405v3 that wouldnt get past the betaflight splash screen when there was an sd card plugged in. other than that stuff just worked.

rc newbie here, would it be possible to make or buy an fpv drone that could fit in a 5 inch tube while also having enough battery/antenna range to fly out to at least a mile?
if so, any advice on prebuilts that i could look at that could get the job done?

yea i think it can easily do a mile battery-wise your limiting factor will be your video receiver. a patch antenna on your goggles will usually do the trick.

you could also try something like a draknight
https://www.youtube.com/watch?v=UoEEAYNc6DE

almost every 2inch/2.5inch drone will fit in a 5 inch pipe, maybe even some 3 inch ones. but you'd need bi-propellers parallel to the pipe direction. if you actually want to fly though a 5 inch pipe somehow thats something only a 65mm tinywhoop can do if its very short

its a babyape i just changed the camera and added gps

if you want long range/flight time its just about weight cutting. get an ultralight frame,lightest engine for that prop size , an AIO board that has ELRS,ESC,VTX and everything. and use a pack of molicel 28As as battery.

some guy flew pic related for 70 minutes, using a carbon strut frame, DJI engines, some kind of cellphone batteries
>>
>>2779180
wait, you managed to fly up to 61 kilometers with
a babyape?

wouldn't it have a hard time with the wind?

i was under the impression that if you wanted to fly longer/further you should get a 7 inch.
>>
>>2779184
Are you seriously asking if they flew up to an altitude of 200k feet?
>>
>>2779184
the problem with 7 inchers is usually the frame weight goes up very quickly compared to ultralight 3-4-5 inchers which can have 25gr-70gr frames.
if you do 7 inch with a custom carbon strut frame like that pic >>2779180 and the lightest engines that will support it without heating up too much it will work.

and no i didnt fly up 60km thats jamming fucking up my gps. the most ive flown with the babyape is ~500m but im about to go try a longer range flight with directional antennas ( 9 dBi 2.4GHz patch and 9dBi 5.8GHz patch)) and i think i might try to fly it long range with a 2s pack of molicel 28a's when i get those in the mail (that will be twice the weight of the 720mah 3s lipos i usually use tho so its gonna fly heavy)
>>

ah, that makes more sense.

the highest flight i've seen was over 7km, so i figured there would be someone trying to see how high it's possible to go.

my only other idea is to use the other UART pads for it (on the darwinfpv-15a-1-3s-f411-ultralight-whoop-aio) so the signal and power is away from the VTX

GPS receivers can be very susceptible to noisy power, especially these ultra tiny ones that have very little built-in filtering. Picrelated was a Beitian that wouldn’t work on the FC’s built-in 5V regulator because of the noise, but worked fine on a separate 5V regulator. It would never lock more than 7-8 satellites, changed the power source & it locked 20+.
>>
>>2779305
would soldering a tiny capacitor at the gps module's power pads filter that shit out?

also i just switched uart ports on the FC and it locked 6 sats instantly (less than 30 secs from power on) from usb. using the same 5v pads. but now my receiver is using the pads which fucked up the gps, guess ill have to fly it and see if it works.

Mob7 with a thumb pro 4k, adding 8g (32g drone + 13g batt) which is very noticeable, and drifty. I know, stop cosplaying as a cinewhoop, but its fun to try shit out, and im pretty sure this is the lightest "4k" (runcam tried their best) cam out there.
Anyways, what's a nice motor/prop combo (or maybe just props?) over stock to carry that weight?

whats wrong with SPI? all that means is that your elrs firmware and betaflight firmware are combined instead of being a separate module no?

i flew my mobula 8 on my 1s 300mah batteries until i got my 2s 530mah one yesterday, its pretty impressive, pretty powerful and lasts almost 8 mins of slow flying around my yard. i got it to put a camera like >>2780227

It can be a bitch to update the receiver firmware.

it's just included with your betaflight firmware no? had an spi receiver on my mobeetle and never had an issue

Typically. If you don't know how to cook your own firmware up, and the manufacturer drops support, good luck.

It was a big issue when they were shipping with ELRS 2.x but everybody had upgraded to 3.x on their radios.

i think current betaflight for such boards comes with elrs 3 built in. its only gonna be an issue if they make a new major version of elrs that isnt backwards compatible and has actual features you want.

worst-case-scenario is you need to solder some tiny receiver on like a happymodel ep2

>>2780255
It was mainly a problem last year when Betaflight had no upgrade path.

I soldered my R-XSR to my board and I'm getting random inputs when I power up my controller.
I don't know if this is my receiver, the FC, or the controller itself.
The receiver is soldered to the SBUS pad etc. I have checked the solder join and it's as solid as it can get.
Previously I was messing with CLI commands https://warosu.org/diy/thread/2751796#p2774125 in this thread and I THINK I disabled the board's inversion (doesn't appear when I type resource in CLI now) and I have no fucking idea how to turn it back on. I'm hoping that just reenabling that will solve the issue.

>factory reset of the FC in betaflight
yeah, that's what i'd do. not sure how but when flashing the FW there's a 'full erase' toggle that does it
it shouldn't enter armed state and spin up motors with those random twitching that we see in the video
>>

A reset of the FC isn't a bad idea. If that doesn't fix it, try another receiver. Remove the props as well if you haven't already as it's a serious hazard to be randomly doing full stick deflections.

I’ve worked with drones on & off for 7-8 years. Starting out with basic aerial photo/video, inspection & photogrammetry survey work as part of a larger role, then more recently a full-time role flying long range (50km+) BVLOS medical delivery in controlled airspace.

The low end of the market, your basic bitch aerial photography & gutter inspections, has been made so accessible via ~$100 ‘licenses’ that it’s completely oversaturated by every single weekend warrior with a Mavic. There’s no money to be made here.

The top end of the market, your serious cinematography gigs or inspection work for big energy companies, require ‘real’ qualifications & experience, the kind that cost many thousands of dollars & take years. There’s no money to be made here unless this is already your career.

As for the new/novel uses of drones like delivery, it’s all startups burning through VC funding chasing business models that aren’t financially viable yet. There is potentially money to be made here, but expect to be treated like complete shit.

i wish you could just use a vr headset as an fpv headset.

its probably not even that hard i installed a standard android capture card program on my android VR headset and i can see the FPV feed from an external HDMI card connected to the capture card connected to the VR headset's usb port.

the problem is that most regular android apps you install that werent specifically made for vr just run as a flat,stationary 2d window inside your vr headset where's i would want it to be full screen across your entire field of vision or part of it even if you move your head.

it's probably not even that hard i just dont know shit about android development other than making the most basic shit like a flet app in python.

i think a quest 2 VR headset + radxa 3w computer as VRX + RTL8812AU wifi adapter would be the openIPC FPV headset that can pull double duty as your regular home vr headset.
quest 2 is 200$, radxa 3w is ~30$ , basic RTL8812AU card is 20$. thats a ~250$ FPV headset with 90Hz monitors, 1832 x 1920 resolution and 128 gigs storage for recordings + 2h battery
>>

good prop guards are relatively heavy and add a lot of drag yes, also those dji quads are very min/maxxed for long flight times if you stick a piece of gum on them or fly them in any noticeable wind you'll see that number drop

consider a cheap monitor (eachine/hawkeye) if you're just starting off. Believe it or not, the *** was right about LOS being useful, dare I be forced to say necessary for flying...
If you're deadset on getting strapped on, Cobra S is the cheapest worthwhile, but the Cobra X gives a lot more for $250. The next level up 2nd-hand HDO's. Endgame goggles are an HDZero+Analog setup, but I feel like that's soon to change with more OpenIPC hardware.
If I was starting from zero I'd probably go the HDO route and throw money at OpenIPC.
>parts
microcenter is only really good for soldering gear, or befriending the 3d printing guy to print cam mounts/ducts/spare parts.
Getfpv/RDQ/Newbeedrone are all reputable stores, and hell, even amazon has parts. I would even tell you to buy Amazon batteries (tattu/GNB/ovonic), so your normal drone store order doesn't get tied down by forced ground shipping.
Banggood is a real crapshoot, but if you're deadset on certain parts, just order direct from the CN company's website (which will probably redirect you straight back to BG lol).

blogpost: it works, can track any drone with ELRS and a GPS.

did a small test flight at 1km range with a shitty 200mW vtx and it was fine. could probably go further.

the bottleneck now is the ELRS telemetry, for some reason the moment i lose telemetry it wont pick it back up even when the drone is right next to me so if you lose telemetry even for a moment the tracking stops. idk how to solve this

my plan now is to mount a jumper aion TX elrs module on it with a 9 dbi directional antenna, fly it at 50hz and hope it never loses telemetry. im waiting for the adapter for the tx module to arrive in the mail

At a certain point you should really just switch to Ardupilot & use it’s very mature antenna tracker support.

nah this thing is relatively simple its a stock off-the-shelf antenna tracker. the only complication i added is a raspberry pi so this thing can connect to any edgetx radio's usb port and take the telemetry.

I'm still trying to find out what exactly happened.
I hit a branch, immediately the vtx went full snow, elrs failsafed, and it disarmed mid-air. From there, I recovered vtx mid-fall, and crashed (20ft fall (200g)). Lost VTX a second after impact.
After inspecting:
The warm battery pack seemed to have voltage on all cells with no puffing or noticeable damage. Too sketchy to use again.
The ESC got hot enough to desolder most of the motor wires, and I was lucky(?) enough to have the - battery lead desolder from the ESC, disconnecting it before a fireball.
While some of the mosfets just desoldered and moved, the mosfet on the bottom exploded, leading me to believe that's what caused the short.
All other electronics besides the ESC seemed to be in working order (FC, elrs, VTX, gps, all ok).
Theory? A mild branch hit in just the right spot to overload a jammed motor, blowing up a mosfet, shorting the battery, and resetting the FC mid fall.
>>
>>2784433
i had no idea it could get hot enough to desolder mosfets and motor wires from just jamming a motor, i thought it could at most blow the mosfet (like internally)
this seems to me like a short that lasted multiple seconds from something that got loose in the crash.
>>
>>2784617
That’s exactly what anon is saying. Crash blew the fet, which itself caused a short. An IC doesn’t have to fail open circuit, it can fail to a dead short.
>>
>>2784599
That's wild! I wonder my little homemade bassline will see such destruction one day.
>>
I forgot to mention, the only thing that doesn't add up is that the motors draw just under 10amps at full throttle, so I thought I was pretty safe with a 13A (15A peak) ESC.
Can a jammed motor really draw enough amps to blow up the esc?
I guess the answer is yes, and now I'm paranoid enough to print ducts for all the props...

On a semi-related note...
Years ago, some guys and I used to go on annual fishing trips to lakes up north, mainly for Northern Pike but also Bass if they were in season. We never knew where the fuck the fish were because it seemed like they moved around year-to-year, and so the good spots would change each trip. I threw out the idea of building a drone with some kind scanning function to fly out and check the spots each morning and report back where the most fish where, but we could never think of what exactly to scan for from above...
Anyone ever build anything like this before, or have any ideas?
It was a pretty big lake (7 miles end-to-end, with lots of coves, bays, and streams) so it would probably have to be a fixed wing project.

>Nreal Air + Wifi Adapter

I'm not familiar with openIPC gear at all but I'm pretty sure you're setting yourself up for pain and/or failure going this route. I own both normal analog FPV goggles and a pair of lightning/displayport USB-C smart glasses similar to the nreals and there are just a lot of great reasons not to take this approach. If you absolutely must do it this way, your best bet is to build a proper ground station with antenna mounts, batteries, etc centered around some kind of laptop or portable device with proper lightning/displayport compatibility. Last time I wandered through electronics stores plugging my glasses into everything with a displayport sticker, that meant either a macbook or a flagship samsung phone - nothing else worked.
>>
>>2785621
>that meant either a macbook or a flagship samsung phone - nothing else worked.
I have Nreal Airs, and they work with both my Sony Xperia IV and my Asus laptop. You need DP Alt support, not just DisplayPort.

I agree they don't seem great for FPV though. I'd use them as an impromptu addition to a monitor, but the FOV is poor as a dedicated goggle.

i have this working with analog video >>2782541
the white thing behing the battery board (with the 2 18650s) is the nreal adapter.

i was originally planning on making analog goggles out of the nreal airs by having
>battery shield
>analog to hdmi adapter
>hdmi to nreal usbc adapter
in my pocket (all in a single 3d print)and that orange cable thing going to my glasses where the analog VRX is mounted on the side

all i need to change it from analog to openipc is replace the analog VRX with a wifi stick and the analog-to-hdmi adapter with the radxa 3w. when all that shit works well ill make a magnetic mount for the wifi stick so i can put it either on the glasses or on the antenna mount so i can easily switch between antenna-tracked-flying and 'normal' flying

>>2785621
>I own both normal analog FPV goggles and a pair of lightning/displayport USB-C smart glasses
what type of DP glasses? i own nreal airs and a samsung phone that is compatible with them. but there's also the HDMI adapter so i can connect any HDMI input to them.
>>2785627
they have ~45 degree FOV, 1080p OLED screens and are like 80 grams. those are pretty good specs compared to many FPV glasses. the main thing which stopped me from using them is the screens arent that strong in full daylight outdoors even with lightblockers so i designed a light blocker for them that covers the sides

eventually ill just give up and buy one of those expensive digital fpv goggles, maybe the new walksnails

Neat, I am about to order a 14.2" wingspan Sopwith Camel (should also weigh 50 grams or less) and a 24.2" wingspan Dragon Rapide (should be 100 grams or less).

I know, I am an RC Boomer (sorry), wait until you see how much stuff I use that was made by Hobbico/Horizon Hobby.

Also, is the Hobbyking Mobius to FPV conversion any good? I want to get one for and use it on one of my Mobius cameras.

Thinking of building a long-range fixed wing FPV drone.

Haven't built fixed-wing in over 10 years, and back then I built with balsa. That design was a relatively short wing, but a long range is going to require a large aspect ratio. Is balsa still the preferred option?
>>
>>2786068
Just seeing lightweight PLA for the first time, at 0.8 g/cm^3 vs balsa at ~1.1 g/cm^3. Might be useful for non-PSE parts?
>>
Any of you guys tested the waters with cheapo chinese thermal units?

>>2786068
Foam is king.

>>2786072
Nope, LW PLA has horrible strength and cracks easily since it's just thinned out regular pla. This Guy >>2786107
Is correct.

My city is designing a new park
I wonder if I can get them to include a drone obstacle/racing course
>>
>>2786233
how many people fly drones in said city?

you can just fly there anyway or put those hoop race gates around if you wanna race
>>
>>2786235
Actually, quite a few. It's a nerdy tech town, and we already have two FAA approved/designated areas in parks for flying. One is just for RC planes and the other is for planes and drones, but they're both just wide open fields. That makes sense for the RC planes I guess, but with an FPV quad I want to go over, under, and around stuff.
>>
>>2786240
More luck asking them just to plant some trees.

>>2786240
I just said fuck it and fly my yard or ask permission to fly at other places. Government approved shit will always suck ass.
>>
>>2785971
Graphene pack? C rating? The power system is closer to something in the 30" class (2S and 3S 850-1300 packs are common).
>>2785985
People still buy Mobius cams, because of how reliable and how easy they are to modify compared to more modern Foxeer and Runcam units.
>>2786068
Honestly, balsa is great for keeping weight down, depron of 1mm and 2mm thickness is also good, same for Pichler Super Board, they rest are shit for DIY (except for EPP, but you need some extra tools for that one). I am a little bit biased since foam board is a cheap material in both the good and bad sense.

When somebody says "le foam" they are not specific enough, and trust me, a lot of foam is hot garbage for DIY RC projects. My first DIY fixed wing project was with EVA foam and it was much too floppy.

Also, foam needs spars. Light plywood is best for weight savings, followed by carbon fiber tubing/flat runners. Carbon is heavier for what it is and for how much is needed compared to light plywood.
>>
>>2786264
I do not even bother with permission, no tracker, TRUST will not be renewed, expired AMA (fuck them). Glowies can stick their regulations where the sun does not shine.
>>
>>2786448
Wait, TRUST has a renewal? I hope mine is expired. They lost all of my respect by pushing RID as hard as they have. Was planning on being a boy scout about the rules, but this is retarded. I might've even done it if they allowed for open source modules to broadcast, but even that was too reasonable for them. Instead they expect expensive, oversized modules that serve no purpose. They can suck my nuts.
>>
>>2786460
TRUST was supported by the AMA. AMA was mostly responsible for helping launch RID too. AMA wants to end park flying (by conspiring with manufacturers like Horizon Hobby and ShenZhen FreeWing), as well as nitro (I am going to be buying an engine soon in order to make a small model that can serve as a tow plane, I think an O.S 40 FP or K&B Torpedo 40 might do the trick).

At this point, what the FAA does, the AMA supports in exchange for an exception. They also play favorite to member clubs. My local club (which I had to leave thanks to the AMA) received $70 in funding this year, while the field in a big city about 125 miles away received eight times what we received. We have two fields, whereas the other club has one and because of how generous the AMA is, we have to abandon one field by the end of this year.

So I am going to fly, unregistered, unmuffled nitro in the local parks by the end of this year and the AMA can kiss my hairy ass for doing it.

P.S: TRUST Renewal is not official, but it is going to be one of the FAA's next moves, just like how registration was initially "permanent", but now has a renewal scheme.

At the GPS module's power pads you'll want an electrolytic cap of a value of 10-250uF across the power pads. This will help large voltage swings.
A .1uF ceramic cap across the power pads may help. Check out local thrift stores for cheap/ unwanted electronics. The part is only .02$ but the shipping is way more. I just threw out all my components in the move. Otherwise I'd just mail you anons it for free.
>>
>>2783581
This rattles me. There is no such thing as "500mW RX". Is it actually drawing a half a watt on receive?
>>
>>2786674
my understanding is that it transmits telemetry at 500mW not that its anything special on the RX side
>>
>>2786560
I never liked anything about the AMA, including the people who show up at their fields. It's always a bunch of stuck up old men who hate anything that they're not used to. I'd fully expect to catch a bunch of shit for FPV, 3D printing, ELRS, a flight controller on a plane, and multirotors. If it's those old fucks helping to push this shit, no wonder the fun parts of flying are getting killed off. Should fly long range over their stupid field and drop a can of dog shit.
>>
>>2785887
how are you finding it, I want to get one for indoor flying/ outdoor but mostly indoor, was going to print some prop guards if I do get it
>>
>>2786684
Some of the guys at my local club are good people. One was a long time nitro flyer who just started indoor since he wanted a challenge (he is 89, by the way). People like that I can get behind.

I would say 95% of the AMA and any AMA club following current rules are as you say, my club up until this year was compliant with the 1996 handbook and it was kind of comfy.

The AMA itself is horrible and FTCA is not really any better. I am looking at starting my own org, but all the legal overhead is a pain in the ass. I know guys who would join.
These are my goals:
>Decentralized field regs, but recognized member club list.
>Openness to all forms of RC, air, land or sea. (Maybe even free flight, rocketry and control line/tether cars too).
>Free to join, but donations are welcome.
>Club gov. is only in charge of advocacy and fundraising.
>Events to get kids and the general public involved. (Free or for donation to help advocacy, just not $100s for stuff like the AMA Camp, which still used 20 year old Robbe Wingos until maybe two years ago).
>Maybe some edicts for disobeying FAA, CAA (et al.) laws too.

I think that so long as the club is based around common sense, we can do good. The problem is organizing this. (I probably need a paralegal, but I have no money to pay them).

XT30 and A30 are my favorites. My only gripe is that they should've moved the metal cuff of the female end back a little.

kek thats literally what i did initially, its too big for indoor get a tinywhoop if you wanna do that

mine is kinda heavy with the hawkeye camera,gps, and 720mah/1100mah GNB 3s batteries i usually fly it with. it lasts like 6-10 minutes depending on how agressive i go and how the winds are. honestly i like it i got it as just a secondary quad to fly when im working on my big one or i cba to get it running and stuff like batteries for it is cheap + can i use my big 6s packs as field packs to charge my small 3s packs chich means i can get a shitton of flight time on it.

>>2786926
i put A30 on one of my tinywhoops but other than that xt30/xt60
>>
>>2786926
I'm a surface RC pleb atm but, XT60H.
deans can be fine if it's tight but could cause shorts if it walks out, tamiya/molex can get loose pins, TRX/TRX ID secures fine and is easy to grip but it's overpriced proprietary shit targeting a certain market. I haven't tried EC3/IC3 yet.
>>
>>2786913
You are right, a lot could go wrong, I probably need a second and maybe even a third opinion.
>>2786959
Unfortunately, that is the problem, since we need international membership. We also need to at least close to the size of the AMA, BMFA, FTCA, et al. I think that I will write a piece for a news outlet on the issue, I am thinking of doing an aviation news website, then two mainstream outlets, right and left.
>>2786926
As much as I like XTs, I prefer EC2s and EC3s, since they are easier to solder. Worst plugs are the red JSTs.
I knew a guy (passed away) who preferred Anderson Powerpole connectors, I might give them a try one day.
>>
>>2787008
don't give up, at least put some more research into it. I wouldn't waste time on a local newspaper, you'd be better off talking to local schools and colleges and going the STEM route like FT has. The end goal is to get the FAA to recognize your org and working with education will go a lot farther than "i like my planes govt fuck off," even though that's basically been my thoughts too. The few rules we had up until recently were fine, it's only since the explosion of DJI flying cameras that the public started noticing. Even then I don't think people care that much, but the commercial lobbyists started going after Congress for more rules for recreational models to keep any obstacles towards their bullshit out of the way.

Remote ID is fucking retarded. If it communicated on ADSB then I could see an actual safety benefit, but it doesn't. It only becomes useful if someone is breaking the other rules and anyone who bothers to install it would be following the other rules.
>>
>>2787026
I will not give up. I was looking at AvWeb, Fox and ABC to run this story on-line as part of a guest column.

AvWeb have featured some stuff I wrote in the past. (https://www.avweb.com/features/reader-mail/top-letters-and-comments-january-8-2020/, poll section, fifth one down). I was a kid (16) at the time and my writing has improved, so I think it might be time to do it. I liked both Pauls (now retired), as well as Russ (though he has made some enemies on-line), so I think if I am rejected, I can at least work with them.

What I need is more data (sauce, if you will), to make an even more compelling argument.

Maybe I can then make a thread on RCGroups as well. A lot of boomers either hate the AMA or are only in it because they like the local club too, so I think I can find support.
>>

i think dji controller can run on 2.4ghz which is much better for cables. you can run it with an RG402/405. IIRC this is the type of coax that comes with all the FPV antennas between the connector and the emitting part. it loses ~0.5-1 DB per meter so you wont get ideal range but it will work

Yeah, in that case I meant to say prop guards not proper ducts.
Reasoning is to stop debris from stalling the downward props, but I also wanna test if it gives me any more grip like a cinewhoop, even if it's only on two motors.
As for the legs I really like the leds for vlos, but I'll fly and test it out, see what happens. If it doesn't fly well I'll just switch to cf tubes like the front.

DO NOT buy the Goggles X unit for analog. It's been nothing but problems for anyone I've ever talked to. I've been on the Sky04X with Walksnail addon module. Walksnail is getting me to places I'm blind on analog and HDZero, and the picture is still clean. While I love that part of it, the project has been pretty ghetto for how costly it is and how old Caddx is. They're basically just creating ghetto DJI.

yea ive read that their analog input is garbage and shows full snow on the screen when the signal is still flyable in other goggles.

i still dont get how this could happen sine the goggles in this case are getting video only and have no idea what the reception is.

my plan is to use an analog-to-hdmi board, theyre literally like 3$ off aliexpress if you want one. ive flown with one and it works (pic was my first attempt at an analog-to-HDMI ground station)

drone noob here gathering info

thinking of building an 5" pfv drone with googles but don't want analog, so - digital with 60 fps, and walksnail seems to be along the lines of my needs as I don't plan to join races.

so, if ya get get a cam like any of the walksnail cams with an antenna, it's enought to send a signal to the googles, like Googles X, I don't need a separate receiver on a drone, correct?
are receivers only necessary for analog builds? i am somewhat inept so pardon my stupidity

also would love some suggestions on stacks and motors. want to add GPS too but walksnail supposedly has that covered
>>
>>2789351
Not a bad idea. Hopefully they've got their BS sorted with the overheating display on one side. If it weren't for the hardware fuck ups I probably would've bought that set myself. Good luck bro!
>>
>>2789384
For the video system, you'll need a camera, VTX (Video Transmitter), antennas on both ends, VRX (Video Receiver), and something to display the image. With Walksnail goggles, your VRX is built in. As for the stuff that goes in the air, you'll see full kits everywhere.

Don't forget that you'll still need something to handle the control link, so a receiver is still needed on your quad. They're two separate systems.
>>
>>2789384
fpv quads usually have 2 radio systems, one for your control over the quad and one for the video from the quad to your goggles. you need a control signal receiver like an ELRS receiver on the quad and a video receiver on your goggles (walksnail goggles have one inside)

>also would love some suggestions on stacks and motors.
take any youtube build guide and just copy it or use the build linked in the OP. replace the analog camera+analog VTX with walksnail camera+vtx

>want to add GPS too but walksnail supposedly has that covered
i dont think its related, walksnail is the video system. the video system takes data like gps from the flight controller (to display on screen).

GPS Rescue is a very useful function to have in your back pocket. If you take that route, be absolutely sure to test it out in a safe spot (unmowed grassy fields are excellent) before falling back on it. Odds are you'll be on Betaflight, and autonomous GPS functionality is very limited. That mode has saved me twice in three years. All other uses were testing to be sure it worked right.

What could cause the signal issues I'm experiencing?
The example video is at 1.5 km out, but the problems start to occur around 500m (and get worse the further I go).
As you can see sometimes it is "okay" but then it will go crazy. So I can't do any low flying which is what I really wanna do. And generally it is an unpleasant flight experience.
Is this most likely interference, or some issue with my antenna or something else?
My vtx is HGLRC 800mw.
I have a TrueRC X2 Air on my goggles.
I want to be able to go at least 3-5 km with reasonably clear video for low-ish flying.
>>
>>2789576
I see bars in that static. Bet there's something stomping on your signal. Are you keeping the control TX away from your face while you fly? Even a different frequency can interfere with reception if it's strong and close enough.

I wish I had the cash to dump on even a cheap one. Would absolutely rig it with a camera switcher and dual mount.

Mostly. You usually end up running wires instead of plugging things into sockets, and you gotta supply correct voltages, but beyond that it's pretty much the same. Building a computer is like 2/10 for difficulty, and a quad tends to be like a 3 or 4 just because you usually need to solder and sometimes make custom mounts. Still piss easy once you understand what you're doing.

the thing you posted is basically a GPS chip from a company called ublox, it's an ubox M10. almost every company that makes fpv drone electronics takes those chips and makes a GPS module (like walksnail did in this case). pic related is a gps module from flywoo that uses the exact same chip.

every GPS module that uses the M10 is basically for the most part the same. (there are small differences like bigger ones have bigger antennas which means better gps lock)

theres lots of guides on how to set it up like
https://www.youtube.com/watch?v=dQeNONerxEU
https://oscarliang.com/setup-gps-rescue-mode-betaflight
but my advice is dont worry about it, get a drone flying first and do your first flights in a place where you wont lost in in a forest or something.

what i very very highly recommend as a beginner even more than a GPS is one of these
https://oscarliang.com/drone-buzzers-with-battery/
if you fly around a lot of forested and bush areas you WILL lost your quad at some point and this is what will save you. speaking as someone who lost his first 5 inch within a pretty small but extremely overgrown area and spent an entire day trying to find it with no success

>>
>>2789885
At minimum you need power (2 wires) & video (1 wire).

The other wire allows the FC to control the channel/power. If you don’t connect this, you will need to select channel/power using the physical button(s) on the vtx. It will remember the last channel/power you used, so it’s not a huge inconvenience - but FC control does allow for nice things like automatically reducing power when you’re sat on the ground disarmed, so the vtx doesn’t bake itself.

Nah man, that's 5V Out. Give 7-36V to the DC pad. The 5V Out pad is if you don't have some other source for 5V and need to power a camera. It's good for a standalone rig like on a car or simple plane.

all the numbered pads like RX1/TX1 and T2/R2 and such are the UART ports of the flight controller. these are the ports you can see in betaflight when you connect your flight controller to the betaflight configurator on your computer via usb.

for example in pic related (one of my quads) UART 1 is my GPS. UART 2 is my ELRS radio and SOFTSERIAL (basically another uart) is VTX(IRC TRAMP) which means its connected to my vtx and controls it's power level and channel.

TX6 in your pic is like that it only sends data to the VTX (tells is which channel and power level to run at) which is why RX6 isnt connected like a regular UART connection.

these ports are usually interchangeable you can connect it to any UART TX pad on your flight controller for example T1/TX1 or TX2 you just have to tell the flight controller what is connected to that pad (pic related)

also the rushfpv VTX uses SmartAudio and not IRC tramp so you just pick that on the menu instead
>>

>far better range and video than I am

This is an important part. Once saw a guy do a 6S6P battery pack on a 7 inch quad. Dude flew from a very tall hill and did 22 miles out on Walksnail. His ELRS2.4 control link stayed at 25mW most of the way out there. Getting away from the ground just gives so much benefit.
>>
>>2790247
>6S6P battery pack
how the fuck do you even charge such a thing. every balance lead is connected to like 6 cells.
>>
>>2790276
Parallel connected cells balance between themselves, it’s only series connected cells that need external balancing.

Any large commercial pack will be internally paralleled. For example my 8000mAh 6S is actually a 6S2P pack, but you wouldn’t know that unless you removed the wrapping.
>>
>>2790276
I think he has it rigged as 6 6S1P packs, and there are 6 plugs to attach packs to. 3 on top, 3 on the bottom. My own quad does just that with a 6S2P configuration. Both plugs go back to the ESC battery pads.
>>
but how the fuck does 6S6P even fit on a 7"?

5 miles? Wow. I would love to get that range.
I feel like my signal improved slightly by switching the tx crossfire antenna from vertical back to horizontal. But I need to test it more as I didn't fly as far this time. It still wasn't great at only 1km. Hmm maybe I should switch the transmitter off completely and see if that improves things...

>>
>>2785638
With arducopter software, you have a trigger function (it can change a pwm signal coming out of your FC when you press a button on your RC). That can turn a servo which presses a trigger and then goes back.
idk how much recoil you would get. I figure you would need a second servo connected to a turny button to control gun elevation. You can easily point the drone in the direction of the target, then judge the elevation by eye.
I think you'll find that every shot causes the drone to wiggle significantly and so adjusting your aim would be difficult unless the projectile is so fast that its basically a straight line.
A fun project would be to mount a laser rangefinder next to the gun. You press the trigger, it measures, sends the range to a little MCU that is also monitoring the angle of the servo and the attitude of the craft along with wind estimates from the craft's KF. THen the MCU would take control of the gun servo and point it in exactly the right direction for a hit. The limitation might be the accuracy of the servo angle and how stable the hovering copter is. At any rate you would learn a lot about physics, electronic engineering etc It would be very educational.

you can try ELRS airport

you can use an ELRS RX/TX pair for this and if you ever dont need it anymore you have a space control link for a drone.

ELRS receivers all use the same protocol over a UART or SBus connection. It really doesn't matter what you pick since they all speak the same language. If one works, they'll mostly all work. There's probably some weird edge case that won't, but since they're all so cheap it's not like that matters too much.
>>
>>2791408
regular ELRS already does this i think in the telemetry
ive used the GPS data to drive antenna tracker in >>2778369 but you can extract the other information as well.

you just set your ELRS radio to 'telemetry mirror' mode, connect it via USB to any computer (regular pc, raspberry, whatever) and its gonna start sending all the telemetry via COM PORT
you can run this python code on the computer you connected to your radio to parse and print the telemetry
https://github.com/crsf-wg/crsf/wiki/Python-Parser
you can easily modify this to do whatever you want with said telemetry

also any regular edgeTX radio can automatically log telemetry.

Color on your shell looks great. Nice color shift.

Love driving the RC10. Its a worlds rere that I picked up extremely cheap at the end of the production run. Very nostalgic taking it out to the track and guys giving thumbs up seeing it. Need to rebuild the stealth trans/ball diff, but parts are really starting to become expensive and hard to find. However, with the recent release of the 40th Anniversary edition, there is renewed hope of more parts production. RC10talk guys found on AE's site its showing stealth parts are showing availability in late May. Also I found a guy (Fan RC) is now making aftermarket replacements for nearly every part, so its really starting to look up using it as a runner now and not a shelf queen.
