Question: Information: - In aircraft, a V-tail or "Vee-tail" (sometimes called a Butterfly tail) is an unconventional arrangement of the tail control surfaces that replaces the traditional fin and horizontal surfaces with two surfaces set in a V-shaped configuration when viewed from the front or rear of the aircraft. The aft edge of each twin surface is a hinged control surface (sometimes called a ruddervator) which combines the functions of both elevators and rudder. - Butterflies are insects in the clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, along with two smaller groups, the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). Butterfly fossils date to the Palaeocene, about 56 million years ago. - The Monnett Monerai is a sailplane that was developed in the United States in the late 1970s for homebuilding . It is a conventional pod - and - boom design with a V - tail and a mid-mounted cantilever wing of constant chord . The kit assembles in approximately 600 hours . It has bonded wing skins and incorporates 90 flaps for glide path control . The fuselage is of steel tube construction encased in a fiberglass shell . A spar fitting modification was released in 1983 . A powered version was designed as the Monerai P with an engine mounted on a pylon above the wings . A Sachs Rotary Engine was chosen for the prototype . A version with extended wing tips is also available ( Monerai Max ) which increases the span to 12 m ( 39 ft ) and raises the glide ratio from 28:1 to more than 30:1 . Both the powered Monerai P and the unpowered Monerai S versions are identical structurally . - A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium (generally air or water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft) or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tilleressentially, a stick or pole acting as a lever armmay be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics. What is the relationship between 'monnett monerai' and 'aircraft'?
