Wing Overloading and Deformations of a Model Glider

Justinas is a "self-confessed" risk-taker who is fond of gliding. He conducted research do with wing breakages and aircraft deformations caused by overloading. Using a model glider he first measured its speed before having it perform the "Nesterov" loop and other complicated aerial manoeuvres. During these turns he further calculated what might be the maximum overloading possibilities for his craft. The results he obtained were compared to a copy of the wing's deformations. He concludes that breakage in the air is possible, especially while performing acrobatics and other manoeuvres because the wing breakage momentum is so close to critical.
