Smallest brushless quads?

Has anyone built a really small brushless quad?

There's quite a selection of mini quads around using 5" props (and I've built a couple myself), But I don't think I've seen anything smaller, not as an off-the-shelf frame kit, anyway.

Looking at the NanoWii control board, and maybe a set of 6A ESCs, it looks like it's got to be possible to go a fair bit smaller with mostly off-the-shelf parts... maybe about halfway between Ladybird-size brushed quads and models with 5" props?

So has anyone given it a try? - are there suitable motors (smaller than 1811s) and props (3-4"?) available?

yep lots of vids on youtube search "micro brushless quad"

1S brushless quad copter(nano wii) testing_byJang (1 min 49 sec)


palmsize brushless quadcopter (3 min 50 sec)


or "nano brushless quad"

Nano quadcopter wii (2 min 22 sec)


Multiwii Nano Quadcopter V (8 min 41 sec)


even typing the above into google works, so why couldnt you do it instead of posting a thread asking to be spoon fed free information?

One reason I can think of is the terminology. Nano, Micro, etc.. quad, quadcopter, copter,multi,multirotor, I'm intertested in this myself, but more for a octo or x8. And I found that searching using variations yielded varying results because of the mix use of terminology.

What about the nanoquad from Flyduino.net?
I just started this built using all off-the-shelf parts.
5" props, 6A ESC's, tiny motors (although the price is pretty big).

Description:

The frame is designed for the nanowii flight controller.
I used this controller in another build an it's rocksolid.

check out warthox his video abusing this little quad.

Didn't MIT build these quads about the side of a finger nail 10 years ago.
If you want a small quad to fly yourself though, Flyduino Nanoquad is the one.

Although as they are a bit pricey a lot of people use Turnigy 1811 2900kv

Does anyone have anymore info on the nanocopter quad wii in video number three posted by neobot? Google doesnt give me anything but i assume it might be on a french forum or something. If someone could translate what hes saying in the beginning i would be grateful, the only thing i can see from the video is that hes using 3a esc's and maybe these motors http://www.hobbyking.com/hobbyking/s...ade_mCPx_.html

4.6 gram weight 3700kv

I hope they work on your build. I'm still trying to figure out what to get for my Nanoquad. I just can't see spending $150 for a set of those T-motors.

Yeah im also trying to figure out what to get for my build, it looks like 3x2 props is the smallest prop you can use and still get decent lift so now im trying to find some good motors.
Im also not sure if im going 1s or 2s yet, 2s would make it easier to use the flight battery for fpv too.

But accoring to this http://der-frickler.net/doku.php/mod...cro_motor_4_6g the motors only provide 52g of lift with 2s and i would like to get closer to 100g.

Ive found this test that gives 120g lift on 22700 rpm with 3020 props on a 4000kv 17g motor with 26w of power usage. http://www.wattflyer.com/forums/showthread.php?t=57635

I think the ad-c5 motors have to low watt rating to get the prop speed up so im looking for some more powerful ones close to 4000kv and still light weight. So far ive found these but i havent found any test data on them. http://www.hobbyking.com/hobbyking/s...ner_Motor.html

I also i have one of those i linked to first from project i never used so i might test it with a 1s lipo and see how much thrust i can get out of it.

And i agree those t-motors are to pricey. And i have more rc gear then id like to admit so now i want to find the right motors without having to go to trial and error but build threads for nano brushless quads are hard to find. Every thread i find seem to use 5 inch props.
