The thought of adding weight makes my teeth curl up! NONE of my planes have any extra weight added. Yet some people have weights everywhere you look. I just don't get it.
If you think CG is that critical, consider that it moves a half inch or more as fuel is burned off. Can you really tell that if flies different at the end of the flight? I usually can't.
OK, I realize it must balance within the recommended range. But I don't understand the need to add a couple washers.
