DISPLAYTITLE n ellipse In geometry , a multifocal ellipse also known as n ellipse , k ellipse , polyellipse , egglipse , generalized ellipse , and in German Ehrenfried Walther von Tschirnhaus Tschirnhaus sche Eikurve is a generalization of an ellipse with multiple foci. More concretely, and given n points in a plane Focus geometry foci , an n ellipse is the Locus mathematics locus of all points of the plane whose sum of distances to the n foci is a constant. The set of points of an n ellipse is defined as math left x, y in R 2 sum i 1 n sqrt x u i 2 y v i 2 d right math The 1 ellipse corresponds to the circle. The 2 ellipse corresponds to the classic ellipse. Both are algebraic curves of degree 2. References J.C.

The Mini Ellipse is a miniature radio controlled glider designed by professional RC pilot Jaro Muller and distributed by Euromodell . The almost ready to fly model features a hollow moulded fiberglass foam fiberglass sandwich wing skin with carbon fiber spars added for strength and a one piece V tail . Hardware is included but the modeler must provide the radio system of his her choice. Wingspan is 58 1.47m . A seven channel radio control radio system is recommended, but the Mini Ellipse will operate on as few as four channels. Ballast can be added to gain more speed with the disadvantage of more weight. The model can be bought as an electrical version, too. The wings and V tail are the same, the fuselage has the place for electrical motors. Model weight for electrical versions is about 800 gramms, with state of the art motorisation brushless and power sources LiPo the mini ellipse is a little hotliner .
