The 737 is the only in production large transport aircraft which can be flown with pure muscle power in the event of loss of hyd. power. To enable the forces the yoke needs to transfer a large amount of torque, ergo the large travels on the roll and pitch. Having flown the 737 for more then 18 years, every time I jump into the 777 or 310 Sim I initially overcontrol and have to deliberately reduce my inputs to avoid oscillating.
