The Thrustmaster Cougar Throttle is a beautiful device. It is made entirely from metal and conveys a strong feeling of authenticity. But it is not without shortcomings:
The stock pots are rather cheap and tend to produce unpleasant spikes after some use due to dirt on the sliding contact inside
The axis of the throttle lever is held in place by two plastic bearings. Even though everything is well lubricated, the stock throttle displays an annoying “stickiness”. In order to change the lever position, this initial stickiness needs to be overcome, often resulting in larger than intended control movements. The problem is a combination of stickiness and friction, hence the term: “Sticktion”.
But there is help out there! CubPilot “Cubby” at http://www.cubpilotshangar.net has made it his task to make the excellent Cougar products (and other input devices) even better. He offers contactless, ultra precise Hall sensors as a replacement for the stock pots and an Anti-Sticktion kit for the Cougar Throttle.
