I'm on 6 hours training at the moment in a French C150 and loving it, im confident enough to do circuits and my instructor has the confidence in me to not touch the controls the whole flight. When I did my first landing it was the best feeling ever and im pretty sure the instructor didn't touch the pedals even then. Maybe your instructor had a bad turn with a student when he had the rudder on landing/takeoff?. Just tell him you would like to take full control for at least one landing to show him you can do it without bad things happening. On a near solo flight i do find this baffling he doesn't trust you yet.
