Oh it's definitely weakened because of the stress risers that the threads create. My point is that it is still far stronger than the 56 oz that these servos put out. If I were flying something bigger then the point would be well made though.

wjcalhoun, In working this out myself, I wanted to put a straight piece of all thread though farther up in order to get the horns at the hinge line, but there isn't nearly enough meat there to work with. On planes you've done this with, did you beef that area up or was the hinge design different to make it possible?
