This is a video of Spencer Lisenby test flying his new Swept Wing Transonic at Weldon with wind speed ranging only between 25 to 32 mph. This model has a lighter layup for test purposes, and handled the lighter slope conditions with speed and grace. Wingspan is 130 inches square to fuse with a ready-to-fly weight of 186 oz (5200 grams).
