VE3KCL writes: "I stretched the balloons to 96" diameter and put 8 grams of free lift in each balloon as with -22. This flight had a small solar panel and a bit bigger battery. As always I was hoping for over 12km altitude but .. there seems to be a hump there to get over. The balloons were badly handled and crumpled during the wait as the launch was postponed 2 times due to weather. Half the gas free lift had leaked out during the 4 day pause. I had to perforate the balloons to put more gas into them this morning before the launch. It seems the high humidity and temperatures were not kind to hydrogen gas retention."
