Taylor D-1 Glider

William Piper asked C. G. Taylor to build an airplane smaller and lighter than the Chummy, Taylor's failed venture. Taylor first designed the D-1 Glider, which had a steel tube frame, lightweight wings, and a tailskid. Taylor and Piper pulled it behind a car to flight test it, while his son Tony Piper noted about its size, “You just put it on.”
