Freedom of Distance
The SIGMA 7 is the top-performing intermediate which makes XC pilots’ hearts beat faster.
The distance easily flies by with this cross country glider, because never before could so much performance be so impressively mastered. This gives you not only the freedom of a greater radius of action, but also allows you the time to enjoy it – a lot.
Advance Sigma 7 > More about...
The Sigma 7 has many outstanding characteristics...
High canopy stability
A well-defined max-lift point on the wing profile and optimal internal pressure characterise the SIGMA 7. These make the glider distinctly more stable and also mean that it can be flown faster in turbulent air. This puts it wholeheartedly within the trend for faster transiting, that is becoming ever more popular with recreational cross country pilots.
The best speed bar position with SPI
The very stable profile, set up for the best speed, responds precisely to speed bar inputs. Accelerator movement is exactly tuned for all levels to make sure that the profile shape is completely retained at all times. In combination with the Speed-Performance-Indicator (SPI) this allows you to achieve a markedly higher average speed en route.
Precise and direct handling
The SIGMA 7 has direct and pleasant handling with low brake loads. This provides precise turn entry, makes progressive radius adjustment possible at all bank angles, and gives you effortless flying. The balance of profile and twist give the required thermal bite.
Advance Sigma 7 > Other Important Details
Narrow risers with a 2 stage accelerate system
The SIGMA 7 speed system has an adjustable ratio change. The length of the travel and its loading can be set to suit the pilot’s leg length and leg position: an initial easy-to-push 3:1 ratio while the legs are bent; then an efficient 2:1 ratio with legs straight.
A combination of line types gives the SIGMA 7 durability and good performance. The lower lines are sheathed to protect them from wear and tear. The middle and upper gallery lines are uncovered, for less drag and therefore better performance. The compact braiding and extra coating of the yarns of the Liros-Competition lines significantly improves resistance to UV radiation and abrasion. The loops at the line ends are sheathed, to reduce surface pressure and wear.
ADVANCE pays great attention to small details.
The SIGMA 7 Pilot
The SIGMA 7 is a high performance intermediate that suits the experienced thermal pilot who has, at least, already made his first cross country flights, and who possesses a good feeling for a glider. He has an active flying style, can recognise and prevent the onset of trouble, and has no problem with fast descent techniques. If these conditions are met the performance potential of this glider can be realised, and the pilot cover the countryside feeling safe and relaxed.
Advance Sigma 7 > Certification
