Longest flight of Spirit mini : 50 km, 72minutes with Li-ion 2S1P

This is longest flight of tiny Spirit mini . Spirit min was only 166 grams, 47 cm in wing span. At first, only 30 km autonomous WP mission was planned.. But, after mission flight completed, too much energy was left, So, simple manual flight was done to test maximum flying distance. Spirit mini did 50.8 km flight loaded 2S1P Li-ion batteries. Maybe this could be world record of flight using 2S1P Li-ion ^^. My micro wings, NanoGoblin, Dart250, Drift, they sometimes did about 40 km flight easily, but, they have not ever done over 45 km flight using 2S1P. The planned mission was low altitude ( 150 meters ) round-trip along the riverside. I am sorry, but, the altitude of last waypoint was set to 800 meters. So, Spirit mini suddenly climbed just before last WP. 43:56 This was unsuspected state, but fortunately canceled mission. But, thanks to this mistake and post rainy state, we can see low altitude clouds 44:48 0:45​ manual launching 0:53
