ALPHA 3 - Technical details
The first impression when flying an ALPHA 3 is : SIMPLICITY and
SECURITY.
Design features :
Reinforced leading edge, with Mylar : better rigidity and stability of
the wing.
Each cell receives a line, to maintain a perfect profile.
The cell width is scaled, it gets smaller as you go from the centre to
the wing tip (the last four being closed off) giving a beautifully clean
aerodynamic shape.
4 risers: easy to handle - for students as well as for advanced pilots
- and giving better speed system.
Compression straps sewn between the attachment points of the
lines : the distance between the cell walls always remains the
same, in order to maintain the profile and keep the shape of the
wing i.e. better performance in the turn.
Construction details :
All of the sewing and stitching is internal.
The leading and trailing edges are reinforced with a Mylar border to
increase rigidity and also to make them less sensitive to the high
tension to which they are subjected.
The winglets on the wing tips are aerodynamic elements but also
ADVANCE signature which, diminish the wing tip turbulence (vortex
effect) and give much more precision in the turn.
The lines remain in correct position on their small quick links
thanks to a plastic clip.

The braking is optimised by using a system with rings creating
braking action on the wing tip first.
The brake handles are reinforced in a way that makes them easy to
take and comfortable. They are attached to the risers with a mag-
netic snaplock.
The wing tips receive a Velcro, easy to open to remove the twigs and
gravels that could have entered the glider.
The big ears kit is easy to use and perfectly integrated to the risers.
The brake handles receive a swivel, that avoids the main brake line
twisting when making a wrap around the hand.
