What's everybody working on atm?

I'm still trying out different 6" props (just got some APC 6x4E & ordered some of the new Gemfan 6042 Flash) & making slow progress on my 7" build. Weather has been awful for flying lately though :(

short answer, yeah, toss
there's a few different techniques. I prefer a frisbee-style launch bu some people do overhead and some people do a weird underhand thing

Does anyone have experience turning used smartphones into fpv googles?
I have an HTC Desire that's in pretty good condition, I thought I might hotglue a little camera and a GPS module onto a cheap mini quadcopter and mess around with that
>>
>>1311976
>can it be done
yes, there are WIFI-based fpv systems that will pair with your smartphone
>is it worth doing
no. Wifi is too slow and the range is very limited. You'd have a hard time actually flying anything through fpv using a setup like that. The best bet for cheap fpv is pretty much always going to be a 5.8ghz analog setup.

So, I'm peacefully taking a dump while pondering existence and it occurred to me that I should get a drone.

Now, money is no object and I was considering a Mavic platinum... because, who doesn't want to spend an extra 150$ for differently shaped propellers.

But then it occurred to me that DJI started rating out their customers a couple of months ago with its "Aeroscope" thingy.

Bad DJI, bad, bad, bad.

So how do I get to build a DIY done with such features such as: long range, 20+ min flight time, gps return to home and the likes?

A quick search shows a TBS crossfire module could easily outperform DJI's, but how about battery and gps bells and whistles?
>>

you would probably be better off just buying dedicated goggles for the same price though

pretty satisfied with my build, this will be the last one for a long time
>>
>>1312110
How long does that one fly for anon? Also, you're not afraid of crashing into a tree and the props slicing those cables running down the arms in half? Just curious.
>>
>>1312095
The simple but unfortunate truth is that you are never going to build something that even comes close to a Spark/Phantom/Mavic in terms of features, performance, integration, etc. even if you spend literally four times the money & months solid working on it. The DIY route is great for race/freestyle quads, but for AP it just makes zero sense.
>>
>>1312154
8-9 minutes with 600mw VTX, over 10 minutes with no VTX. I don't think there's any danger of the props slicing anything, this is a 2S build and those are 1306 motors so there actually isn't that much power, every quad has motor wires running down the arms anyway.

wtf is that meme antenna supposed to be?
>>
>>1312250
It's a cloverleaf/skew planar. It has circular polarization which is the norm for video on FPV quads which frequently aren't topside up.
>>
>>1312254
it's also excellent for rejecting reflected signals from flying around trees or buildings.

>>1312250
it probably looks funny to you because it doesn't have a protective casing. any time you see a mushroom looking antenna, that is what is inside it.

Just upgraded my E010 with 67k rpm motors, waiting for a chance to fly it again to test them out. It really jumped when I hit the throttle after turning it on the first time.

What pids do you run for those spins? I kind of new to freestyle and am curious what others run there pids at.
>>
>>1313194
I'm assuming you mean rates, not PIDs? I run 0.8 RC rate, 0.8 super, 0 expo, across all axis. For me that's a nice balance between slow enough for smooth cruising yet fast enough for snap rolls when I want to. I recently found out these are the same rates Jordan Temkin (Jet) runs & I've always loved his flying.
>>
>>1313194
>the "pro tuned pids" meme
Every build is different, you gotta tune it yourself if you want it to really be GOOD.

I don't doubt what you are telling me. Its just I have no idea what to change to get the different styles race/freestyle. This is new to me and I know there are YouTube videos about this stuff but I cant fucking stand the annoying youtubers. When I fly in the woods my rolls are snappy when I push all the way and slow when I dont. So I don't understand what's tuning going to help if I can just push the stick a little slower or faster.
Sorry if this sounds dumb but I am a brianlet.
>>
>>1313207
that's more of an RC rates and exponential thing then, PIDs is more about keeping the quad stable and not vibrating in any possible situation.
"RC Rates" can be thought of as a percentage. the way the numbers actually work varies depending on your firmware, FC, and configurator, but the basics is that a bigger number means that the quad rotates faster when given stick input. This is important for tuning your "snap" stuff, like rolls.
"Expo" or "exponential" is exactly what the name says.It adds an exponential element to the linear "rates" equation. The purpose of this is that you can change how the quad responds around center stick: make it more or less sensitive. (you'll want it less sensitive in 90% of cases). This allows you to tune for "cruise" flight, as in when you're NOT doing crazy stuff at full stick input.
>>
What is the hot shit in quadcopter flight controllers nowadays?
Last one I had was the KK board with the LCD on it I wrecked into some wet snow and corroded on me.
>>
>>1313223
Depends on what direction you want to go.
For AP and other larger quads, there's not too much going on, I guess an Eagletree Vector would be the "hot shit"

For smaller quads, such as the "racequad" or "miniquad" fad, there's a BUNCH of FC boards out there running F4 processors on betaflight firmware.
>>
>>1313207
>I don't understand what's tuning going to help if I can just push the stick a little slower or faster.

PIDs & rates are two different things.

You change rates if you want to change how fast/slow the quad rotates with stick input. Changing rates can affect style.

You change PIDs if the quad doesn't fly smooth. PIDs has got nothing to do with style.

>>1313227
>I guess an Eagletree Vector would be the "hot shit"

You mean Pixhawk 2. Does anybody use Vector outside of fixed wing?

If you're willing to fuck around with missionplanner then sure, pixhawk 2 is hot.

Sorry to say this, but that's VERY outdated. I'm sure it will fly fine if you just want to cruise around, but you're not going to be able to keep up with any of the freestyle or racing that's going on these days.

>indoor ultra-silent smallish quad that records, stores in flash memory, then plays back speech on a small loudspeaker

Would this be a funny prank?
>>
>>1313411
yes, but also impossible
>>
>>1313413
Why?
>>
>>1313417
because silent and quad doesnt fit together
ive thought about it and the only solution ive come up with is using something like the Focbox or vedders vesk in foc mode but last time i checked that had a 60000rpm max limitation and even then both of these are palm sized esc's

you can build a loud one no problem
but that wouldnt be half as much fun

My 9XR just arrived, along with a frsky rx, but I just now realised it has no module! I was thinking of getting this:
>hobbyking.com/en_us/frsky-djt-2-4ghz-combo-pack-for-jr-w-telemetry-module-v8fr-ii-rx.html
but I don't need the extra rx and would prefer to buy from within Australia so it arrives ASAP. Where's the best place to buy just a 2.4ghz module in Aus for a reasonable price? Cheers

>>1312247
Is that capacitor on the side (against the XT60) for filtering? Do you notice much effect? Mean quad :)
>>
>>1313423
>aus
>reasonable price
RIP
>>
>>1313423
you're hardly going to save any money just getting the module by itself. Just keep the extra Rx, if you ever do another build, you'll have it already.
>>
>>1313423
Certainly doesn't hurt. This thing flew super bad when I first built it, took a lot of tuning, extra soft mounting, caps on XT60 & individual ESCs, etc. to get it flying well.
>>
>>1313442
But yes, it's to filter noisy voltage spikes that ESCs produce, especially with damped light/active braking enabled.
>>
Is my VTX supposed to be getting very hot to the touch?

>>1314689
is it more powerful than 25mw? then yes.

You could try noise cancellation tech or whatever the tech the Bin Laden deathcopter used.

I decided to try a plane, I'm pretty excited even though I'll probably fail spectacularly at flying it.
>>
>>1315821

impressive array of brand new things. Mind if I ask where you get your money? And is it more fun buying things than actually doing stuff with them? I know occasionally I go on a buying spree and wind up with lots of things that I barely use, but six months later when one of them comes in handy I feel like a genius.
>>
>>1315821
I tried a plane once, couldn't get the fucker balanced and it controlled like shit. probably because I bought a cheap body and used the recommended motor instead of something more powerful.
>>
>>1315835
>impressive array of brand new things. Mind if I ask where you get your money?

There's probably less than £1.5k of stuff in that picture, so it's nothing preposterous for somebody that works full time. Pretty sure I earn less than the UK average & I'm not going into debt or anything to support a hobby like this.

>And is it more fun buying things than actually doing stuff with them?

I wouldn't say that building is more fun than flying, but I certainly enjoy building & it's something I can do in the evenings when it's too dark/wet/cold to go out & fly.

>>1315980
That's the price of freedom. Socialism gets me a house here for 1/3 of that.
>>
>>1315993
Just an example (I don't actually live in NY). I could also move west, buy a plot of land and build a house; I suspect doing that in Yurop would be problematically expensive.
>>
>>1316019
Yes land is generally more expensive and scarce here in Europe and I think we have more stringent housebuilding laws. However city living here is more comfortable because the housing is subsidized.
>>
>>1315935
1.5k is also nothing compared to the price of even a cheap car. Hell, my laptop cost more than that, but it certainly doesn't make me a richfag.
>>
>>1315930
Not that guy but I have spent 3.5k USD and I live in third world conditions. I basically am on poverty tier wage and spend very little on anything but my quads and fpv gear.

Turns out direct soldering to 18650 cells isn't as scary as I thought. Tip of the iron was only in contact with the cell for 3-4 seconds.
>>
>>1316355
Why won't anyone release a battery pack with these cells?
>>
>>1316355
>3-4 seconds
considering the professional way to do it is spot welding (10-100 milliseconds) that is more than enough to scare me

>>1316389
you mean... for use in quads? because 18650s are LIon not LiPo, the highest discharge rating you will get is 2C, it doesn't have the output to lift itself. Some sort of hybrid pack with both together may be possible.
>>
>>1316436
>considering the professional way to do it is spot welding (10-100 milliseconds) that is more than enough to scare me

Considering the number of videos I watched with people holding the iron on for a lot longer than 3-4 seconds, apparently with no disastrous results, I wasn't too worried.

>the highest discharge rating you will get is 2C

Some INRs (like the ones I'm using) are 5C. But even then, this plane will only pull about 10A max, so it's a long way from a quad which will easily spike over 100A.
>>
>>1316436
Good 18650 cells can do 8C. I've never felt comfortable soldering them. Manufacturers don't recommend soldering the cells because it's possible to damage the separators/insulators inside. Even if the cell operates normally, it may not vent safely if it fails.
>>
>>1312630
Dayum that looks good, not sure if I want to go back to this whole drone stuff plus fpv. Currently I'm doing weekend woodworking.
