During my first year of building, the 305 is the one left standing.

This is the best and smoothest esc i have ever had

The infinity 305 e.s.c.'s are by far the most robust e.s.c.'s I've ever had. I've burnt up more e.s.c's in my time than I care to say especially the FeTtec 45amp, shoot look at em to long and they spontaneously combust. I've purchased two infinity 305 e.s.c.'s and have them in my kiss builds and running dshot 2400 with absolutely no issues. Both are still running strong even had to saw my way out of a few trees. One look at these and you know they are built right. Great looking and tough as hell. Thanks for the great products. Feel free to use me as a beta tester for future products. HaHa

That is totally a great combination. I wish you would put more wiring diagrams with four different receivers

Just a note that this Stack doesn't have the Flash chip installed on the FC for Blackbox. It is a Rev D board, so a Winbond W25Q128JVSIM (https://www.digikey.com/en/products/detail/winbond-electronics/W25Q128JVSIM-TR/6819722 ) can be installed, and it works fine.

If you buy just the FC (not the stack), maybe you get the flash chip installed?
