I just need a little help.. I seem to loose the calibration settings during a flight, I believe it's the Quadrant unit itself, everything sets up ok in the USB game controller and the FBW A320 EFB, but I do have to calibrate the quadrant unit each time that I fly. Take off, climb and cruise all seems to be ok until I start to descent and then I will loose the calibration on the unit, ether on one of the throttles or flaps, speed brakes, they also show out of sink on the cockpit pedestal....my question is, how or where is the calibration settings stored for the quadrant unit, any help would be greatly appreciated..
