First Rogallo wing build . I used a hobby zone super cub for the base. Turned out pretty good but maiden will have to wait as I just had shoulder surgery. Ordered rip stop kite material from Amazon, my sister in law did the sewing. Carbon arrow shafts for the frame. I cut material on a 90 degree angle and set outer frame at 80 degrees. I set it on the plane at an 8 degree angle. Turned out solid I think.
