Yup FYI just about all the ESCs are running 32 bit bl-heli now I think with some sort of STM32F3 (er maybe F0) or similar on there to basically act as a fancy reprogrammable motor driver 
. Unfortunate thing about when BLHeli went from the older BLHeli-S (8-bit) to BLHeli-32 they decided to close up the source code whereas it used to be open to devs to browse around and poke at it. Not sure where the decision to close up the source came from exactly and honestly doesn't matter to me too much, but I like to see things stay open source so can be built on even if a given company/entity disappears.

Anyhow my thoughts on open source aside it looks like a good ESC, I still stick to individuals on most of my builds but as the ESCs are getting more reliable and less often need replacing it's becoming more beneficial to just go with the 4 in 1 ESCs for a cleaner build.
Really the MCU on there is only important in terms of how quickly it can process where it thinks the motor is in it's rotation roughly and how fast it's going by measuring BEMF I believe, the other major important component on ESCs is the MOSFETs, the choice on those is what drives how many amps you can safely push through them before they cook themselves. OH also 32 bit ones allow you to make your motors play startup music, if that is important to you

We're going with off the shelf ESC for the prototype only, the final design will have more integrated solution. The quad we're using for the prototype stage is a fairly uncommon 280 racing frame to accommodate all navigation components. As the design is optimized, the frame will reduce in size and weight.
