- Page 2 Together with the optimized zigzag 3D shaping, a new level of surface quality is achieved. The ALLEGRO is located in the lower C area with a designed flat aspect ratio of 6. This follows our strategy of realizing small and easily manageable steps between the individual classes.

(and other equipment). If the ALLEGRO is flown in the lower half of the legal weight range, reduced agility can be expected. In strong turbulences a lower stability may be noticeable. The reaction on extreme maneuvers is very relaxed. - Page 4 Turning A turn is an interaction of inner brake, outer brake and weight shi ing. The art is the right dosage. The ALLEGRO is characterized by a sensitive handling. Small brake inputs are enough to fly precise turns.

Landing The ALLEGRO is easy to land. In the final approach against the wind you can flare the wing from a slightly braked position. At about 1m above ground level, the angle of attack should be increased by more and more braking. When the minimum speed is reached, the brakes are pulled to the maximum, the wing then allows a so touch down. -

50% of the span affected, the glider shows a more dynamic reaction: Due to the increased drag of the folded wing, the ALLEGRO will start to turn to the side of the collapse. At the same time, the glider pitches forward as a result of the smaller loaded wing surface and therefore higher wing load and required airspeed. -
Page 7: Frontal Collapse
A er a big collapse or a er a badly executed full stall, a part of the wing might be tangled up in the lines, and wonʼt reopen automatically. This is what you call a cravate. During our extensive test flights with the ALLEGRO we never experienced a cravate... -

Connection with ball and loop: In flight, the ALLEGRO can now be accelerated by pushing the speed bar, which results in a reduction of the angle of attack and as a consequence an increase in airspeed. The speed increase compared to trim speed is about 15 - 17km/h. -
Page 9: Service And Maintenance
Attention: Braking during the accelerated flight not only costs a lot of gliding performance, but as well increases instability and may lead to collapses! Always release the speed bar first, then pull the brakes! To turn, simply shi weight, or push the speed bar asymmetrically. (If you push the right side further, the wing will perform a le turn.) Geometry data of the accelerator If the entire available accelerator travel is used, the A-risers shorten by 18cm or 20cm compared to the C-risers, depending on size:... -

Exceptions are the replacement of lines as well as the repair of small tears (up to 5 cm, which do not affect seams) or holes in the cloth, which can be repaired with the original PHI repair set. A small set of sticking cloth is supplied with the wing. -
