Most of the 150s and all of the 172s I've flown had a rudder trim tab. When set
properly, the planes would cruise without needing rudder input. My C-150 did not
have such a tab. It was necessary to keep a bit of right rudder pressure all the
time. I got in the habit of flying with one foot, except for landing. I had to
break that habit in a hurry when I bought my Maule.
