The design layout
The handiness of the 23m wingspan makes for easy maneuvering on the ground, but especially in the air. A longer wingspan doesn’t necessarily mean better performance. This very thin, high aspect ratio wing, with a maximum of 250 liters of water ballast, allowing for a potential wing loading between 39 and 58 kg/m², makes this sailplane extremely flexible, and with the best glide speed so high, a definite safe bet at competitions.In practice, a completely new level of speed should be possible with this aircraft. We used our network of connections with Lange Aviation and Professor Loek Boermans in the conception and design of the wings. We used nine exact interacting wing airfoils with laminar flow over 95% of the lower and 75% of the upper wing surfaces and based on a superelliptical wing geometry. Structural design, ballasting and the patented, extremely light control design were the work of Lange Aviation. For the Quintus M, the concept of the outer wing panel with the winglets from Professor Mark Maughmer and the classic wingtip sweepback, makes the typical and excellent Schempp-Hirth flight characteristics.The motor operation Operating the motor controls is as easy as thinking, thanks to the new automated concept. To start the engine, one simply switches the ignition to "ON" and after the motor is fully extended, push the start button. The warm-up performance is always optimal, as there is a microprocessor that adjusts the parameters to the particular start conditions. After switching off the ignition, the propeller stops perfectly in place and is retracted fully automatically by the Ilec-control and the help of the propeller brake.
Flight motor 2625-02i
The carburetor and ignition system in the 2625-02i are replaced by a fuel injection and electronic ignition system. The former ignition is replaced by a generator which delivers enough energy for the injectors and the ignition. A controller regulates the fuel flow and ignition timing based on the rpm, throttle, motor temperature, air-pressure and air-temperature. This insures that whatever the altitude and temperature, the enginewill perform optimally.The consistent and uncompromising development will set new standards in the open class. We expect to achieve a new dimension in performance through this new interpretation of the open class, as well as THE ADVENTURE FLIGHT EXPERIENCE for distance, record and roaming flights.
