Curious how much weight the average person is able to shave off their plane when they switch over to primarily glass? Took a plane for a flight today that was at max weight. The current owner stated swapping to glass would save "a lot" of weight but I'm hesitant to believe that statement. He also has an old heavy battery in the plane that could likely be upgraded to a lighter one. There are a few other things that I can think of but the panel seems to be the biggest bang for weight in my opinion.
