I just unplugged the old Saitek Rudder Pedals and didn’t do anything else about them as the MSFS Controls Options didn’t show them. The TRP Rudders installed and attached were seen there which I tried to tweak by sensitivity / dead zones etc but the same issue persisted. It appears as if one toe brake (mostly left one) is somehow pressed because pressing the opposite toe brake / pedal would move the plane in straight line while taxiing.
