V6S is 294g, 2408 2500kv, 6s floss. If you haven't seen it (https://rotorbuilds.com/build/4638), the original Stupid Floss had the Asgard FC. The Asgard had an unfortunate, epic, solder and capacitor exploding, esc burning end. V6S has been upgraded with DYS F4 and DYS 30amp 4-in-1. I don't expect it will last long on 6s, but maybe it will handle 4s better than the original. The DYS combo makes a clean stack with no soldering between the FC and 4-in-1 ESC The only draw back to this setup is the lack of current sensing. The FC supports SBUS (Betaflight 3.1.6 not 3.1.7), and smart audio via the Betaflight OSD.

The 4-in-1 didn't survive the first 6s battery. It was replaced and the current sensor is now functioning. The current is routed through the flight controller and the xt60 has been moved to the rear. Will be flying with 4s.
