The Sail

The wing is the product of one the most experienced flexwing design teams in the world today. The sail fabric
is  cut  with  exacting  accuracy  from  stabilised  polyester  using  tight,  virtually  non-porous  and  tear-resistant
weave  construction.    Double-stitched  seams  using  PTFE  UV  resistant  thread  ensure  complete  panel  join
integrity. Sail reinforcement is achieved by including extra material at high stress points. A Trilam sandwich
leading edge, a Kevlar trailing edge and a spanwise Kevlar tape maintain the wing’s performance over a long
life.

The  aerofoil  section  is  defined  by  pre-formed  aluminium  and  pre-formed  aluminium/composite  ribs,  with
chord  wise  tension  being  maintained  by  attachment  to  the  trailing  edge.  The  predictable  low  speed  stall
exhibited by the Quik and Quik GT450 is achieved by the clean lines of the aerofoil’s leading edge radius and
the spanwise Kevlar tape that limits the wing washout.

The Airframe

All the main tubing used in the airframe is a high quality aluminium alloy from aircraft quality billets using a
special process of mandrel extrusion followed by being drawn to agreed industry specifications. All tubes
and inserts are anodised to give protection against corrosion.

There are no welded components in the wing frame, and sheet fittings are plated, anodised or stainless steel.
All bolts are of high tensile steel. Rigging wires are PVC covered where necessary to afford protection to the
ccupants and to also serve as an anti-kink measure.
