From everything that I have seen, those numbers {30x30, 20x20, 16x16, 26x26} have always referred to the mount spacing, Not the overall size of the board. In fact, the board pretty much has to be bigger than the mount spacing or the holes would be "off the board" so to speak. In fact, the 26x26 whoop board actually measures 33mm x 33mm; it just has a 26x26 mounting and is diagonally oriented.

I realise that, but what's the point of a 20x20? It takes up less space and it's lighter. If your 20x20 takes up the same space as a 30x30 and has the same mass, then why? It also increases the chance that it won't fit into frames designed for _actual_ 20x20 boards.

It's just marketing.

it wont be a benefit for a traditional freestyler but in terms of performance and micros it give more options to build and stay lightweight, ability to use "thighter" "smaller" frames with less surface for better airflow. any tiny piece is a an overall big improvement, just a question about focus.

this aio hasnt the same diameters like 30x30electronics, its as long but not as wide.
i wont buy any 30x30mm electronics anymore, mostly about frame choices. new frames does carry 20x20 for sure but more and more doesnt provide 30x30 mount.
a racing frame designed by a buddy does only take 20x20mm electronics and nano cams, all very thight... pretty sure this aio wont fit in this frame (will fit sideways xD ), but i beleive we will see a lot more frames focusing on smaller diameters overall.

sure 20x20mm mount and large board like this wont fit in any 20x20mm frame.
actual there arent much frames designed for aio boards, as example the original hyperbola frame is specialy designed for the hglrc zeus aio.

why we shouldnt focus for smaller electronics?

Hey, by all means make things smaller, but the cost just seems extreme for this:

YAY

• save 4g over the Flywoo F7 mini stack
  

BOO

• if you want a 20x20 frame you need to be careful because of its size
  
• blown a single ESC? You're out $70. How many spares will you take out with you?
  
• harder to replace in the pit because you have to resolder every single joint if anything on the board breaks
  
• tiny little baby FETs and barely any filtration. But I guess they needed that space for the barometer
  

But I still moan about the marginalisation of indivdual ESCs, so I suspect I'm turning into a grumpy old carmudgeon ;-)

i would like one small board where single escs would be mounted to it, able to replace, but i wont spend a lot more money for this ability, i beleive there is an issue.
tbs has that "white board" where a unify nano and a receiver can be soldered directly. something like this would be nice. an aio platform, able to mount single escs, able to do the aio by myself.

im not so focused about thickness in case of an aio, just about weight and frame compatibility.

edit;
it would be become close to replace single fets xD

30x37

vs

33x33 and at 45'

It guess it all depends on what the frame supports.
A 20mm in toothpick frame will have corners coming out.

Practically same 1100mm^2 and 7g+,
just different holes... move on people... nothing to see here.

Hi Banelle,

Nothing wrong with holding on to what you like. Hey, some like blondes and some like redheads; some like Harley's, some Hondas. 

I don't fix or changing things in the field. I take a few quads and when I'm done, I'm done. If anything goes wrong with one, I just toss it in the truck {do my fixing on the bench}.   

In addition to being old, I am a little eccentric     I like building as well as flying and I often play outside the box.    Just me 

It's good to have build options, honestly.

Even if I might not use an AIO myself, different formfactors suit different build styles, different frames, and so on. I'm glad to see manufacturers moving to increase the ceiling on the performance of these low weight AIOs and small formfactor flight stacks like the latest 16x16 Goku stack.

The argument made against AIOs is very similar to the arguments made initially about 4in1 ESCs way back in 2014-2015 when they first started to hit the market, yet now 4in1 ESCs are for the most part the defacto standard, aren't any more or less reliable than individual ESCs, and have pros and cons compared to individual ESCs. These higher powered AIO, assuming they're designed by competent engineers and end up with a proven track record, could potentially become the new regular. Would that mean the end of the traditional flight stack? Doubtful.

20/30mm stack is not going away anytime soon... for "big" quads.

AIO/26mm boards are convenient, and save weight.
But, few with 3+ UART.
Few support 6S.
Even 45A rated probably more like 30A in real world.
Because so little space, less filtering capacitors and more electrical noise.

Hi Roman,

Yeah, the 30x30 will still be needed for the "big" quads; I would say they would still be used in quads bigger than 5 inch and especially in the X-Class. {with Remote ID of course}.

In the 26x26 whoop format, I have the JHEMCU GHF450, the HIFIONIC F7, and now the BEAST 55A AIO {there may  be others}; 
all of which have more than 3 UARTS. 

I have been using 35v 1000 uf capacitors for some time now and have not had any issues. It might sound like over kill, but it works for me.
