Yea I know, 24 seconds isn't particularly impressive for a glider of this size. But neither would be its weight: at 530g, it's basically twice as heavy as any commerical 1.5m DLG. That being said, it still glides decently, and the flight times will only increase as I get better at discus launching.
This build was just a learning experience, as it is my first time working with composites. I will likely revisit DLGs in the future, with a goal of minimizing weight.
The wing was scratch built out of purple insulation foam, lightly reinforced with 200gsm carbon fiber and double layered with 25gsm fiberglass. Fuselage was 3D printed then same composite procedure. Tail section was made of balsa and fiberglass.
The two main breaking points whenever I crashed was where the carbon fiber boom connected to the 3D printed fuselage (fixed with kevlar), and the 3D printed electronics bay.
