Produktinformasjon
Seilfly med vingespenn på 936mm og Pitcheron System istedenfor vanlige balanseror og høyderor. Det trengs to servoer som styrer en vinge hver, som man mikser inn høyderor og balanseror i. Det trengs også en servo til sideror. Dette seilflyet kan man bygge ekstremt lett, med flyvekt på 115 gram ender man med en vingebelastning på 17,8gr/dm3A quick summary of the design
The Nexus 900 is the result of a long research concerning the optimization ofthe aerodynamics? efficiency at very low Reynolds number, and optimization ofcontrol by pitcheron. The result is a very tinny scale glider, with nearly exactdimension of the real glider (SZD551 Nexus) and high flying characteristics.
Depending of the capability of the driver, it can fly either at low speed than with40MPH wind, always with a perfect behaviour like a much bigger glider.Caution : the Nexus 900 designated to advanced pilots. Despite of its verygood flying characteristics and behaviour, it is not a toy, so please note that it is notadapted to beginner.Due to its very advanced manufacturing, only 2 hours are needed to make theNexus ready to fly.
Items needed for assembly1x: fast cure epoxy glue1x: fast cure cyanoacrylate glue1x: mini driller (Dremell or other)1x: scalpel or cutterand equipments :3x: picoservos,size 4g1x: 3 channels picoreceiver,size 4g1x: lipo cell, 200 to 300 mAh, size 7gPlease note that all the equipment should be high quality ones, as the Nexuscould fly fast and needs accurate response of the control system. Especially, neutralpoint and end of travel of the servos should be perfect and strictly identical.

Forklaringer av fremmedord fra R/C Sailplane glossary - fatlion.com:
Pitcheron - Pitcheron is a term used to describe a plane that has no moving elevator control surface. Instead, the wings pivot together, changing in relation to elevator. This supplies the pitch action that a normal elevator would provide. Typically, a pitcheron plane also is a wingeron plane, in that the wings pivot in an opposing manner to provide for roll control.
Wingeron - Wingeron is the term applied to wings that individually pivot to provide roll control in a plane. There are no moving control surfaces, rather, each wing, by pivoting in opposite directions performs the same function as ailerons.
