Is it a matter of downloading Raceflight to the Sparky2, flashing my B lheli-S ESCs with Multishot... and then what?

BLHeli_S supports regular 1-2ms input signal, as well as Oneshot125, Oneshot42 and Multishot. Autodetected when the ESC sees an input signal.

do i still load up multishot firmware and enable in Raceflight.? i don't understand what is autodetected,. if i load up the multishot what is autodetected

This requires new hardware escs, if you don't have them you cant do anything.

What is so different in new S HW from typical latest ESC design?

They use an EFM8 MCU

So the secret is just faster CPU? Or this CPU is what make hardware PWM possible?

It's a 32-bit STM32 (like your FC) that allows hardware PWM also

At least I assume so, that's what the KISS are I know it's 32-bit for sure, assumption on the STM32 being the choice.

EFM8 MCU is 8 bit according to silabs.com
there is even "8" digit in the name

Hmm, I thought the new ESC's were meant to be 32-bit...??

Nope it's still an 8 bit mcu but is capable of hardware PWM which is the real reason KISS are so smooth, 32bit isn't really needed yet on ESC's and is one of the reasons the KISS esc's are so big

Nope 32-bit is not necessary, only a hardware PWM peripheral.

BTW I think Steffen did some magic and got the top end thrust back on the SEFM. will test tonight, but I expect it to be solid. Much respect for his effort!

And much respect and appreciation for a super test setup and a very good cooperation!
