I use this stack in 2 of my race quads and it's nearly perfect!
The plugs never disconnected or anything and they are super convenient to change broken components like a camera, RX or VTX very quickly!
The ESC is absolutely beefy and I never broke one, even though I smoked some motors xD
But the whole stack still is compact and I can fit a RX and VTX on top of the stack in a Five33 Lightswitch frame.
Only downside I see is that is has no USB-C, but I'm sure that this will come in the future :)
