english: So we looked at the birds, and we tried to make a model that is powerful, ultralight, and it must have excellent aerodynamic qualities that would fly by its own and only by flapping its wings.
non_english: Posmatrali smo ptice, i pokušali da napravimo model koji je snažan, a veoma lak, i vrlo aerodinamičan koji bi leteo sam od sebe samo mašući krilima.
