Our little group of model builders had been flying small outdoor airplanes in a local gym each Friday morning for several weeks when Will Robinson showed up with a couple of models that looked more like true indoor aircraft. They weren't microfilm covered, su-perlight airplanes, but they were fascinating to watch as they cruised slowly about the gym, climbing almost imperceptibly toward the ceiling and descending in the same leisurely fashion. Will offered me a plan for the larger of the two and I couldn't resist. True to his word, he brought the plan the very next week.
