The inflation is a no brainer, the wing progressively comes up and stops by itself overhead. It has a greater speed range and higher glide ratio than the Pil-pit3 which already was a reference in that category. A bullet-proof stability. Even with the trims released all the way, the wing is very stable. The Pil-pit4 9.5m2 has a greater diving angle and is faster than the Pil-pit3, but still has a great glide and the safety of the Pil-pit3.
