Mr Dowson. I have a cockpit at home and bought SAITEK products. One of the products is the Throttle Quadrant. I bought two, so I have to use 6 thrust levers. The problem is not that I'm able to calibrate the thrust levers. When I set the Axis Assignment levers show the range -16384 to 0 and then jump unexpectedly to 16383. This happens with four thrust levers, two of the a Throttle Quadrant and two with each other. Thus thrust levers do not work propely.
If you prefer, I made two short videos (19s) to demonstrate what is happening. The links are:
I appreciate your help and patience.
