C4 Performance you can
handle!
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. |

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. |

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! |
