I am an engineer and an expert on airfoils and I know a lot about materials, stress calculations, fatigue life and a few other engineering things. A solid surface aluminum hinge is unconventional but perfectly safe. The service life should be on the order of 10,000 hours (my estimate only). It will be much less likely to fail in service than an aluminum propeller and you would not think twice about flying behind one of those.
