It's a shame the quality of the potentiometers in the Saitek Throttle Quadrants don't seem to last very long. I was just on their website and it seems to be a huge problem for people including myself.
Problems include spiking to just not working or working erratically.
Looks like I'll be looking for a better set for future use.
I wonder if anyone has been able to replace the faulty potentiometers with a better quality set.
