Eachine Aurora 90

Was searching parts together to build this miniquad, almost finished at around 175€ batteries inc. And then I found this prebuild BNF version.

It has 10amp ESC's, instead of 6amp I had selected to use.(10 not available yet) Has OSD build in and comes with lights. This all for only 142,63€.

Think I'm better off buying this prebuild one.

Also because of the weight this size of quad might become very popular in the future, it is well under the 250 gram limit, so a licence would not be necessary.

After much consideration I bought this one.

All parts loose would be more expensive, even when the price goes up after presale is over.

Can't wait till the little beast arrives.  

It has just arrived, about a half hour ago.

Slightly larger then expected, but small enough to fly inside.

Already got it bound to the Taranis and checked the VTX to see if the video and OSD work.
Everything looking good so far. Only need to set up Betaflight, charge the battery and it can do it's first testflight.

OMG I wanted to configure the flightcontroller in Betaflight and tried hooking up the USB.
Turns out I can't fit the USBcable without removing one of the ducts.

It works!

Was a bit confusing at first, cause after looking at the settings and calibrating the accelerometer, which was all I had to do, I got all kind of beeps and strange sounds coming from the quad. Eventually that stopped and all was normal again. Had to set up a switch on the radio to be able to arm the quad, this was already preconfigured in Betaflight.

Then I could do the first test hovering, not done FPV yet. It flies pretty smooth. Could feel that the motors had a bit raised temperature, but not even warm yet. Maybe in a while I take of the ducts to lessen the weight and try the quad with a small 3S battery.

Does it hover in one place pretty good or does it drift a lot and need
constant attention ?

Looks tiny to me

It is tiny indeed, and there already are even smaller brushless quads.

It hovers quite stable, and flies supersmooth. But it is very sensitive and fast, also had not set up any rates yesterday, so it was not easy to control yet. Need to get used to the nimbleness, and finetune the controls to the behavior. Fun thing is that it can be done inside the house.

Slight problem is the design, which makes it impossible to connect the USB cable without removing the 8 screws that hold the propducts in place. Each time I want to change stuff in Betaflight I must unscrew them, which is quite often. I could remove the propducts permanently, but then I need to find a way to mount the FPV camera, and flying inside becomes a bit risky then.

But I think that is what I'm going to do anyway, the propducts and cam holder are heavy, reducing flight time a lot. I want to rebuild the quad so I can use 3S batteries and do loops with it.

Too bad I don't have a way to record the videosignal atm, really need to find a way to do that.

Took off the propducts and cameraholder, and weighed them. Weight was 20 grams. The total weight of the quad is advertised as 73grams(battery not included), which means almost 1/3 of that weight is from the propducts and camholder.

I think though the ESC's are 10Amps and rated 1-2S, a 3S battery may work fine with the reduced weight.
