Over on the rcgroups forums a user is saying that the dronin fork off Tau works really well for the brushed scisky. It apparently works better than it's stock cleanflight because cleanflight has a bug that limits the motors to around 80% and dronin runs them up to 100%.
When my board and the rest of the parts come in I'm going to run a few tests with cleanflight, mostly to learn a little about cleanflight and to hook a logic analyzer on it so I can see their 80% problem. Then I'll probably load dronin for a couple of days and see how it works before working on getting it to work on LibrePilot.
