One thought on “Leo, Charlie, Tucker

  • Good job! I like the overall design, but I would make two suggestions. 1) make sure you have a steering device; I could not see one on the photos. 2) The back square piece on the body is probably slowing you down. I would remove it so it doesn’t catch air during the race.
