One team, lead by an academic, built theirs without wheels. The academic was a real arrogant, conceited ****. He sneered at any suggestion that Trebuchets had wheels and thus built his without them. The other team was lead by a (non-academic) expert in mediaval weapons and their construction. Based upon medieval sources showing Trebs with wheels, he built his with wheels.
And whaddya know? The wheeled Trebuchet significantly out-ranged the non-wheeled one. And, just as importantly, it out-ranged the longbow as well, something that I'm sure the Treb crew would have appreciated. The programme did an excellent job of explaining the physics of why the wheeled Treb had a longer range, even having slo-mo footage of a little model Treb to demonstrate. IIRC it went backwards, then as the arm approached the release point started moving forwards, giving the projectile additional impetus as it was launched.
They also had cameras set up on the "castle wall" which filmed the rocks as they flew towards to the wall, and let me tell you it was damn scary! Very good program.
