Brian,
First of all, congratulations on your progress and another excellent thread! My wife and I made similar decisions some time ago and we have never looked back. I want to live to fly this RV for a very long time and this is the path to travel.
One point I wanted to elaborate on a bit is that I see a lot of builders going to extraordinary lengths to "keep it light" when it comes to building their plane. Shave an ounce here, an ounce there, and end up with a lighter, more nimble RV, right? But you can only go so far with this plan. Although they do add up, most weight-saving techniques result in fractions of a pound.
Then one day it occurred to me, I'm going to all this effort to make my airplane as light as possible. But the pilot becomes a part of the airplane when it flies. I think when the airplane is weighed at the end of the project, the pilot should be seated in it. That's the true weight you're dealing with, when you weigh your airplane to see how well you built it. After all, it doesn't fly itself! It's not really accurate to take the pilot out of the picture. So if you think about it that way, the quickest (and healthiest) way to take some weight off of the airplane is to take it off of the pilot who flies it. It's easy to overlook that. And here we're talking about pounds, not ounces! In some cases, many pounds. In my case, my finished airplane with me in it will be at least 25 pounds lighter than a few years ago. Keeping that in mind really helps me when I'm temped to stray. If I eat or drink that junk, my airplane will be heavier and more sluggish as a result.
Just a few thoughts to ponder. It's a different way of looking at it, and it helps me.
