Pre-delivery Inspection
The YAK is delivered with a rucksack, the YETI harness (designed specifically for Light flights),
inner bag, compression strap, repair tape and this manual. Your instructor or dealer should have
made a test inflation followed by a test flight before delivery.

Risers and trimmers
The back risers of the YAK are fitted with trimmers that enable the pilot to adapt the glider’s
behaviour to match his level and the chosen slope. Trimming down (shortening) the back risers
makes the glider slower, the handling less responsive and more forgiving, so suitable for pilots
that have less experience. Trimming up the risers accelerates the glider, see accelerated flight
for more details. Ask for the advice of an instructor who specialises in Speedflying in order to
better understand and exploit the trimming system.
