I too was missing the servo_blh parameters, until I found the thread about that. I’m even more confused now. What firmware version should I be using? Where is the Chibios passthru video? The BLHeli documentation doesn’t mention any of this, and that is where I went first. It was working until I upgraded firmware to the latest stable build. I don’t mean to ome across as angry, but I’m frustrated. Can we maybe settle on an operating system and a way to oonfigure blheli32?
