Everyone's running the Floss, so I'm going to try something different. So far, it's looking good.

The Emax Magnum AIO Stack definitely helps with the build process. The pads on the ESCs are really close, so take your time if you decide to get this All-In-One stack.

I inserted rubber o-rings between the FC and the 4-in-1 ESC, it's not for soft mounting, but rather a way to fill the gap as the supplied plastic spacers were not tall enough. Since the FC connects to the 4-in-1 ESC via pins, you have to be careful with soft mounting the stack. I've never broken the connector, but if you want you can reinforce it with hot glue.

I don't know what those black little components on the 4-in-1 ESC's are, but you'll need to shave a bit off the side of the plastic spacers to be able to screw them down.

I'm running Betaflight 3.1.7 at 8k/8k and DSHOT 600.

I still need to recalibrate the current sensor, as the readings are inaccurate.
