The hinge point type hinge is not balanced. meaning it does not have support from the same side of the hinge (i hope that is understandable). the natural failure would be for the pin to turn in line with the stress then pull through one of the holes, that’s what mine did.
My concern is not the hinge breaking, but rather this type of plastic is how they will stay glued in. it has a habit of stretching, bending, when ever stressed and that would break it free of the glue holding it, in short order. I have on occasion found a hinge point that has broken loose of the glue holding it (when things are miss aligned slightly). I’m afraid a perfectly aligned set of hinges will break them selves free just from flight loading
