The second quadrant sets itself to default each time I start a flight. I use my left one for speed brakes plus engine 1 and 2 and the right one for engines 3 and 4 plus the flaps. The default controls for the quadrant is lever one controlling all engines throttle, lever two controlling all engines prop, and lever three controlling all engines mixture. If both are set to default they fight each other as they are both trying to control the same setting.
