I was part of the way through writing up my second post after @Vampyre9 posted the zip file that I remembered about the way the Breeze launches. There was a YouTube video a couple of years ago that showed what occurred when the filter glass was fogged or dirty. The Breeze would launch and gain altitude for about 20 seconds and then shutdown the motors and fall back to earth. The odd altitude in Vampyre9’s log finally dawned on me what was going on.
