Primary control surfaces for roll and pitch are controlled either by a wheel (C-172, Concorde, ...) or by a center-stick (mirage 2000, most gliders, ...). Wheel tend to be used for bigger aircraft. E.g. I don't know any airliner fitted with a center stick.
What is the biggest aircraft (highest MTOW) fitted with a center-stick? (Airbus style side-stick are excluded.)
