This is a sneak preview of some Betaflight 4.0 code that just got merged into the master. I was invited to test it out. Obviously, a lot might change between today and the January release of Betaflight 4.0, but for now, I'm really impressed.
The key feature of this code is that it dynamically raises and lowers the lowpass filter cutoff value as the throttle goes up and down. I think the results speak for themselves.
