This unusual radio controlled model glider designed in an unconventional scheme: on the one hand, the idea of carrying the fuselage (or “inhabited wing”), the other — hard power structure, constructed as “Rama”. The technology of making a model is the light-tight foam of the rigid elements of the bearing lining. The most loaded zones are enhanced with pine slats. This applies primarily to longeron nodes and edges, as well as composing, not having the foam “cores”, rudders and ailerons with a soft covering.

Despite the use of the filler melkosortnogo polystyrene foam, density of detail varies. So, the density of the center section, covered with glass fiber epoxy resin, is 12 g/дм5, wings with a covering of paper — 8 g/dm2, and the fixed elements of the empennage, similar in design to the consoles of the wing,— 5 g/dm2. The tail boom is made in form of tubes made of fiberglass. The lantern, closing the compartment of the instrument, made of hot-Plexiglas with a thickness of 1 mm.

The proposed airframe is simple to manufacture and technologically advanced, and its construction does not require complex tooling. Ballast is used to balance almost pronounced a model could be abolished, if you set the on Board batteries uvelichenii capacity.
