Since I didn't like the rocking action of the pedals, I modified them to feel more like the GA aircraft I was used to flying. I removed the heel supports from the metal pedals and drilled 4 holes - 2 near the top and 2 near the bottom. I made wood blocks from piggybacking two 2x4 pieces of wood together then cutting a rounded taper so the blocks would "feel" like a pedal with horizontal motion instead of rocking. These pedal blocks also moved me the 3" or so nearer the pedals that I needed to be when I was sitting in the seat so my legs weren't so straight out in front of me. The floorboard allows my feet and legs to change position for comfort.
