the other advantage of the 150 (mine’s a model L from 1973) is that the flap lever can be used gradually, it doesn’t have to move in ten degree notches
The Cessna flap system does give the pilot the ability to raise or lower the flap very gradually and also to the flap deflection the pilot chooses. This ability wasn't lost with the "Gated" upgrade. There isn't a notch or lock at intervals which must be used. The surface plate is profiled at each ten degrees giving both a tactile and a visual positioning but you are not committed to these, you can still raise or lower the flaps gradually and position as you choose.
