The first time I tryed taking off and landing from a sitting position was tough for some reason but now I do it often with some planes.
I always bring a lazy boy type folding chair to the field. A buddy and I will fly our "Slow" fliers towards the end of the day, these will typically fly 20 to 30 minutes of casual, conversational flying. Typically just him and I so were not tieing up the flight line. Greatway to relax, talk and enjoy flight. Easy on the legs.
