Airborne Windsports C4

airborneclimaxc4


The VG Cam system is an efficient and simple way to change the geometry of the airframe in flight. The Cam levers extend the cross bars, thus changing the nose angle of the glider, which in turn tightens the sail to give an increased glide angle. This system allows the bottom rigging to remain tight in the loose VG setting, giving the pilot a much more solid feeling when ground handling for take-off. Because the cross bars do not change position, as with conventional VG systems, the static balance of the glider remains constant as does the anhedral. The centre section on the C4 is manufactured in house on a CNC miller and the cross bar wedge is made from solid 7075 alumininium. The cross bar ends are milled in house from solid 6061-T6 and are bonded into the carbon fibre cross bars. Stainless steel pins are used to connect the cross bar ends to the wedge plates. The CNC works to + or - 0.1 of a millimetre tolerance.


Manufactured in house on our CNC miller the nose wire clip allows for quick and easy attachement of nose wires, and the crossbar pullback on the C4 is easy with the 2:1 reduction. The pullback easily locates into the quickclip. The keel, and front and rear leading edges are made from 7075 aluminium.


The top control frame holes are finished off with neoprene.


Features include new airfoil profiles, new tip geometry, more double surface, taller keel pocket for a stable high speed airfoil at the centre section, a new under surface panel layout, reduced wing twist and exceptional sail constructed of PX 20 leading edge. The main sail is made from "Matrix" Polyester laminate with a 13-degree warp oriented X-Ply Polyester yarn. A light weight Taffeta is laminated to the cloth for extra durability.


Streamline clip tip battens are constructed from virtually maintenance free 7075-T6 tubing.


Optional features include Microdrag Control Frame, streamline Control Frame, and streamline Control Frame Option with Carbon Microdrag base bar. This option offers the advantages of the most comfortable carbon base bar in combination with the narrow streamline control frame uprights for an easy grip on foot launch.
