      Hovercraft Orca-1 is designed for outdoor activities, learning piloting, and can also be used for other purposes. WIG is designed in a tandem, which made it possible to significantly reduce the size. Known disadvantage of tandem - shading rear wing, removed by reducing the distance between the wings to the point where the wing begins to show the effect slit. As a result increased the critical angle of attack.
      Reduced dimensions possible to increase the strength of the design. As a result, WIG a robust as a boat and airy as a airplane. Thus solved the basic dilemma when airy the WIG easily break, but heavy is not economical.
      Hovercraft safe and undemanding to use. Piloting on the screen when the height is less than a meter, does not require the pilot of the same experience as mode airplane.
      Pusher propeller installed in the feed, in order to protect a propeller from a water. Such an arrangement increases the reliability of operation a hovercraft.
      The bottom consists of reinforced a ski center and two side floats. This allows you to operate on a water and on snow. Floats are easily removed for repair. The bottom ski of polyethylene or teflon. In the latter case it is possible ride off from grass.
      WIG has a frame made of lightweight fiberglass profiles, fixed sandwich panels. Paneling is made of fiberglass, coated on the inside with a thin layer of polyurethane foam.
      Hovercraft equipped electronic stabilization. This system makes it possible to hop off on a steep wave. In Flight mode on the screen, the system facilitates the pilot relax.
      Basic instrumentation includes a pointer speed, tachometer, engine temperature gauge, fuel quantity indicator. As an option the ultrasonic altimeter on the range 0.1-3m.
      Important feature of WIG - is increased structural strength, which is typical for training aircraft.
      The price WIG half the cost of seaplanes.
