RE: How safe are homebuilt planes?
What tolerances? Both types have virtually the same tolerances. That is if you are talking about internal tolerances..... I would like to see how long a car engine would last running at 75% for 2000 hours.... A nick in a propeller blade is where propeller blades break, (kind of like scoring glass to break it) I will look for the link that I saw that shows how much propeller blades flex in all flight regimes, both wood and metal.
