I like both CA hinges and Kletts.A properly installed CA hinge is very strong.If the hinge breaks,it is often because too much CA was used making it stiff and brittle.I use them in my smaller planes.Yet I don't think I would use them in 1/4 scale or bigger.The Klett pinned hinges would make more sense to me.Just my thoughts on the subject.Its all really personal preference.
