So let's update this: Your motors idle but won't respond to throttle inputs from your radio, however you can see the throttle channel bar moving in BF. Also, when you tilt the quad, the motors respond. Seems the only answer is that for some reason your ESCs aren't receiving any commands. #1 cause would be that your ESC signal wires are connected to your board incorrectly. I've had this exact same issue happen to me before and it drove me crazy for days. Turned out that I had the white signal wires from my ESCs connected to the ground row on my flight controller instead of the signal row
