This was done by putting both feet on the pedal (engine idling so maximum force could be applied by the booster) and push as hard as we could. An average person can put a few hundred pounds of force on the pedal. I plan to do the same on the plane. It might be best to block the pedals to avoid excessive load on the rudder cables (or maybe we should test those, too). Then no matter how much load is applied when moving it will be less than the pressure to which the system was tested. Gary Casey
