Don't use Duco to hold motor stick bracing wire! It is subject to creep failure in that it yields under a continuous load. The result is that the bracing comes loose during a flight if Duco used to hold the wire ends eg at the front. Ambroid gives a stiffer and probably stronger joint.

Well so far I've only reported the density of solid Duco. The goal is to test the relative strength of two equal glue weights: Duco against Ambroid. I'm soliciting for ideas about a good valid "joint strength test." I'm imagining a large butt-glued joint pulled to failure with increasing weights. But that may be testing "sheer" property more than tensile hold. Maybe still valid, not sure.
