RE: longitudinal dihedral
First time , I just lost it, out of view.It was a nice Italian summer afternoon.Flying over a corn field, she picked up a strong lift and in few minutes, I couldn't see her. Tryed to push elevator down but nothing...The owner of the fields phone me few days later (we are good friend!). The glider land exactly at the vertical of his land in between of 2 corn field, no damage at all.
2nd time was also a warm partly cloudy summer afternoon.I went under a cloud and up she went so quickly...but I was aware this time and give motor plus down elevator till I saw her again and landed safely...
