I have a FCC-1 (yes, the first generation) and the FCC-3. Both work famously and the customer support is so good that I’d buy the next generation if there was one with significant improvements.
That being said, if you can deal with a positional stick and don’t have to have a FBW static stick, the stock WartHog FSS is a great value and can be made to work with your Cougar TQS using RealSimulator’s USB adaptor (TUSBA).
