NOTE: The unit is stock is a 6 servo wing. This is how we plan to stock them into the future.
This is the Alpenbrise (alpine breeze) a 4 meter glider designed by our friend James Hammond. The Alpinbrise is available in two layups, the standard and the Super Sport. The Super Sport, has additional carbon in the layup providing greater stiffness for high speed performance flying.
The airframe was designed with the alpine soaring discipline in mind but this ship also excels at the slope and the Triangle GPS class as well. The nose of the fuselage was designed "round" to be able to accommodate a spinner if the plane is to be electrified.
The flight envelope is described as an "all rounder"; making good use of marginal lift on light days and displaying excellent energy retention when ballasted for high energy days. The Alpenbrise sports a relatively high aspect ratio at a bit over 22:1. This gives a good balance between all out speed and agility in turns but also distributes lift more evenly over the 4 meter wing. This improved lift distribution allows better performance when flying lower wing loading, while simultaneously providing increased tip stall resistance.
The wing planform in my opinion is gorgeous with its semi elliptical lines and small wing tip cords; if thats not special enough, there's the "sinusoidal" wave spar on the inside.
