What is the heaviest aircraft fitted with a central control stick? 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.)
The biggest I can find is at 585,000 lb the C-17 has a center stick but depending on what you mean by "airbus style" this may be disqualified. 

Other contenders: 


The SR-71 had a MTOW of 172,000 lb and had a center stick 
If you consider the time it spent in the atmosphere as qualifications for "aircraft" at 240,000 lb the Space Shuttle had a center stick
