Of all the days to show up at the field without my camera. I caught what I could on my cell phone. One of the members had a real nice AeroWorks 100cc Extra 260 with a Desert Aircraft 100cc horizontally opposed engine. He also had a solar panel charging system that he built himself. I believe he said it was a 10 watt panel that charged 2 pb batteries for charging NiMH batteries in his airplane. See the video below. It’s also on our video page.
