C4 Performance you can handle!

Download brochure:

Performance you can handle is a phrase that has been used before in our sport. We could think of no better words that could best describe the brilliant performance the C4 delivers along with it's easy handling. Many hours of developement have gone into the C4. We feel we now have the perfect compromise, a sail fit that matches the frame in it's differential VG setting. This all equates to a glider that handles and lands so easily in the loose VG setting to a glider that will give you optimum glide in the VG on setting. The C4 is a true competition glider straight off the shelf with performance you can handle.

			VG Cam System. This system is an efficient and simple way to change the geometry of the airframe in flight. The Cam System has advantages over other conventional VG systems. 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.

			C4 Centre Section: The centre section on the C4 is an engineering work of art. Totally manufactured in house on our CNC miller 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 our carbon fibre cross bars. Stainless steel pins are used to connect the cross bar ends to the wedge plates. The CNC allows us to work to + or - 0.1 of a millimetre tolerances.

			Nose Wire Quick Clip: Another part manufactured in house on our CNC miller the nose quick clip allows for quick and easy attachement of nose wires. Makes attaching the nose wires easy in windy conditions.

			Pullback Quick Clip: 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.

			Sail work on the C4 is of the highest quality. To get optimum performance and looks we finish off the wire holes and the top control frame holes with neoprene. See the latest specs on the new C4!

Features • New airfoil profiles • Cleaner sail with a new sail cut. • More leading edge wrap • A new leading edge tensioning system • A 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 • A new under surface that looks near perfect in flight. • Reduced wing twist • Competitive high speed glide performance • Easy to steer on climb and on glide. • Predictable landing characteristics. • Internal Stability Compensation gives unsurpassed stability throughout the VG range. • Cam Vg System allows constant anhedral with increased travel. No need to lift the pilots weight to pull VG on. • 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. • Light weight, with 7075 main airframe and tubular carbon cross bars. Streamline clip tip battens are constructed from virtually maintenance free 7075-T6 tubing.

Optional Features
* Microdrag Control Frame Option: See description below.
* Streamline Control Frame Option. See descrition below.
* 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.
* Carbon Leading Edge Inserts, for increased leading edge definition at high speeds
* Custom Colours, for the best looking flying machine around.

			Streamline Control Frame Option. The control frame uprights are a narrower profile than the standard frame and the CNC milled corners have been designed with a low drag profile. The aluminium speedbar is also faired along its entire length for low drag

			Microdrag Control Frame Option: This is the optimum control frame available for serious competition pilots. The downtube profile is thinner and the chord is wider than the standard frame, the milled corners connect neatly to the airfoiled carbon fibre speed bar. The speedbar is aerodynamically shaped and then rounded at the hand grips for pilot comfort. Another advantage of carbon on the speedbar is that it does not transfer the heat away from the pilot’s hands as much as the aluminium does in the cold at high altitudes.   Quick pins are used to release both ends of the speedbar.     Even the VG jam cleat on the Microdrag frame is faired in.
Note: Carbon Leading Edge Inserts are also and Option for the C2!
