Cool, the green and red line are the detent settings. Advance throttle to the afterburner detent, and just before it goes over, left click set AB. Then go all the way down the throttle to 0% and right click, to set the cut-off. You could set it to bottom of the first detent, but the x52 doesnt have huge range, so i leave it all the way down so i dont accidentally turn off the engine.
