There is no gramm of material wasted, it is just stiff enough to support the fuselage and stay in an efficient shape. As a cantilever wing with such a high aspect ratio the structural design driver is stiffness rather than strength. That's why the load safety margin is ample. With no wind ca. The nose wheel can be rotated off quite soon so that the take off run is on the main wheel only.
High concentration is required to keep the wings level with bad low speed roll control authority.
Of course MTO power is applied until a slight rotation of a few degrees lifts us off. As soon as cruise altitude is reached power can be reduced. We modified an old sailplane trailor to accomodate the large dimensions, specially the high fuselage. The largest wing segment is 7.50 m long. To make fly a human body on his own low-sy power is quite a challenge.
