I'm halfway through my phase 1 testing and I've run into a frustrating issue. The lower aft edges of the canopy plexiglass interfere with the lower forward edges of the window plexiglass when I close the canopy. My best guess is that I built the canopy in my basement and the ambient temperature outside has been 20 degrees warmer than my basement. Has anyone else run into this? Is there a better solution than shaving back the edge of the canopy plexiglass to eliminate the interference?
