あった〜・・・これだね。
The pilot is me. The glider is very old. 1993 flight design a4. The brakes were near zero level. And the wind was not strong. I think the stall was because of the paraglider was so old and about my weight. 85-114 glider. Me 120kg with glider

フルグライドで飛んだが機体が古く（エアー漏れ?）風は弱かった
それに加え過重量で飛んだのがストールの原因だと思う。ってところかな
