Maybe not, but it's pretty much the same as MWC 2.1 as far as I know. At least it's configured using the same tool and whatnot.

in an email from Timecop:
You already have latest firmware, so it's not strictly necesary to upgrade,
I don't plan to add anything new except bugfixes (and haven't been much of those) until mwc 2.2 is released.
To that leads me to conclude it is up to par with 2.1 currently, and since its the same batch as Wiseducks..

And the barometer, yeah its a sticky wicket, I heard it can get all over the place.
Outside air has plenty of airpockets and flying fast gables the the sensor if you dont pad it.
But does that hold true to a tiny quad that will stay indoor and not fly very fast to begin with?
Its something fun to screw around with I guess. I'm sure ill be picking it out of the Christmas tree plenty before the year is over.

I've already soldered the pins to mine. I might buy another one of these, or maybe two more. I have a warthox frame here that I just purchased, this tiny thing could easily fit between the two plates if you solder the signal, ground and positive wires to the pin holes on the board. That would look so nice. A super clean quad with no visible flight controller.

Im gonna go ahead and solder the whole thing right onto the board without headers because I dont plan on making any other miniature quads anytime soon.
Besides, the extra size of having headers to keep it exchangeable doesn't weigh against the price of just buying another one anyway.

The thought of it squeezing right in between the plates intrigues me greatly though, havent thought about using it that way.
That would make my bash quad neigh indestructible and a lot more appealing to boot (and room for more leds!).
Damn you Wiseduck, stop planting expensive ideas in my head!

I wish right-angle headers were included with it instead. Regular headers make it way too tall to fit between the plates on my Warthox frame. It's already difficult enough to make this thing look as clean as some of his own builds.

Go nuts. :P I bought a strip of these off a local shop, but its only pennies and so very handy.

I'm a little torn though, I want to use my bluetooth module to setup my machine, but I dont really want to put headers on.
I wonder if I can somehow temporarily hook it up without really soldering it, so I can just take it off after im done.
Maybe plugging an unsoldered header into the BT module, and clamping it on with a rubber band so it keeps pressing it down.
Getting the PID right takes a lot of fussing about with tiny quads, so Im not particularly looking forward to hooking it up a thousand times.

This guy Ulix from french forum made those boards. I think they're the most little you can find for now

Thread is here:

Prop he use on his frame compared to ladybird one, look at this:

He made his own frame as ladybird was too big for him

Bloody hell, thats so small! And it seems it has ESCs built in, too.
Cant find price or shop or anything though. I bet it costs an absolute fortune.

For me this size would be pointless, since assan receivers cant get smaller then 32x17mm
Still, really impressive!

You need those nano spektrum RX for this:

There's no need of any Esc, it's brushed motors, you just need 4 mosfet. They are already embedded in the board .

So I got my little afromini here, hooked it up to an FTDI programmer, and tried connecting to it through MultiWiiWinGUI 2.1 and Naze32Gui.
It seems to to connect or at least boot up (LED flashes), however I dont get any functionality out of it.
After connecting, graphs remain dead, and I cant save/load any PID settings.
Windows says the adapter is "Silicon Labs CP210x USB to UART Bridge (COM3)" so that should be alright.

Trying to change a setting in Naze32Gui even throws an error:

I should be able to access it without having anything else attached to the board, right?
Am I missing something important?

1) could you access it via CLI?
2) use latest GUI, not 2.1
3) error is from some .NET stuff... MultiWiiConf can't throw this because it's written in Java, so probably nicodh tool. But you're using old version - i told you already to ask nicodh for new version...

Anyway, 1st step in verifying would be - connect via CLI and 'status' output.

1.) The CLI through naze32 configurator stays blank.
2.) Java is garbage, id REALLY rather not use that.
3.) My .NET framework is up to date, nicodh's tool is from september so its not THAT old..

I guess I should find Putty or whatever and try to get it to talk with that..

Figured it out, I had RX/TX hooked up backwards.
It doesn't work by matching labels like with my multiwii boards,
but I guess RX <-> TX does make more sense.
I got her hummin, its all good now.
CLI on nicodhs GUI kicked in, goodness its so easy with this!

Just a little whatsup.

Its probably not the smallest one, but the 2.5" props do not permit any smaller.
I wish hobbyking would hurry it up with my bag of crud so I can finish this thing.

Parts list, now! I can find several 1S ESCs over at Hobbyking but don't really know which one to pick. Also, what about the ESC from Supermicro? How much do the motors draw? Where can I find them?

This is a very interesting project, I'd love to do this as well. Now... When I think about it, I could get some CF plates from Hobbyknig and simply use the CNC machine at work to make a frame. What is the M2M distance? Width of the arms? Where'd you find the props? AHHHH!

I think I've found some of the things needed.

300x100 1mm CF plate
2.5x1 combo, 3x CW, 3x CCW pack
3x2 combo, 3x CW, 3x CCW pack (For experimentation/extra lift)
Supermicro 3A ESC
Hextronic 2g 7700kv motor

Also need a smaller receiver, but FrSky doesn't have any micro receivers that can do PPM. Only the 4ch one with the full range antennas, hmmm...

What else do I need?
