I use Thrustmaster’s Rudder Controll System (RCS), bought in the mid nineties. Theese pedals are made from thick aluminum rails, resulting in a sturdy and almost undestructible device. Over the years, the original system went through a couple of modifications.
The first thing to go was the original pot. It became unreliable after less than a year of use – even the Windows calibration screen showed wild spikes when the pedals were moved. As a replacement, I installed a precision pot that worked well for several years.
