not saying that 8-bit is something bad by default.
There's some nasty stairstepping in the throttle of even the latest VGood firmware, and there's still a lot of sync issues being reported. Also top-end thrust just isn't there. There's just a lot more capability there that can be explored.

As far as 8-bit vs 32-bit, it doesn't really matter when/how the technology was made, what matters is if it's the right application, or if it is a limiting factor. For what we're doing in terms of brushless ESC control, 32-bit doesn't have any significant advantages over 8-bit other than the fact that ithas enough overhead to be programmed in C rather than assembly, but abstraction can also be a disadvantage in certain instances. For future development, 32-bit may become advantageous soon, but even given the advances in BLHeli_S we're still well within the capabilities of the 8-bit 48mhz chips. Also there's the fact that the STM32F0 chips are significantly more expensive than the 8-bit chips. I'm not saying we shouldn't explore 32-bit options, just that it's an unnecessary expense at this exact moment. Of course that will start changing rapidly as we start exploring two way communication and other ways of dealing with control. Like I said, we're still a long way from the end of the capabilities of the processors we're currently using.

just saying 8-bit vs 32bit, I remember when it was said 640k of memory was all you’d ever need :-)

Well, nothing to do with the 8/32bit discussion, it just came into my mind, sorry off topic

Team Shendrones
It sure is a hobby in it self to follow these technical advancements, can't wait to try this stuff. Great job guys!!

Yeah.... Only in some months we got from standard 8bit 16mhz to 8bit 48mhz... Never say never... And extra processing power/bandwidth is always welcome...

Is this going to be open source? I didn't see it under your account on Github.

I think it's under testing yet, should be soon.

I sure hope one of the new blheli_s escs come with a big fat electrolytic cap on it.... like 30a 6s support. thats the one i'm getting :P

Got 'em yet?

I'm holding out on these rather than (1st choice) XM30As or (2nd choice) Kiss24A Race Eds.
