Night soarer with built-up structure: 1 min 17 secs, 3.24MB A short video of Roy Harrowell’s solution to night soaring. Roy constructed a ‘Built-Up Zagi’ with LED’s mounted inside the structure to illuminate the entire solarfilm covered wing. This Zagi is light in both senses of the word - it shows up in the dark well and weighs about 70% of an EPP version!
