Guys,

The reason Comp-ARF say not to use ball links on their phenloic horns is due to the fact that a ball link has to be fitted to one SIDE on the arm. This means that, when under loads, the phenolic arm is open to a twisting load. Most composite materials are much better at absorbing loads in particular directions and it is the same with these horns. The material used is extraordinarily strong when handling straight on loads that would be induced by a clevis but not as strong absorbing a twisting load hence the warning of not using ball links.

Rgds,
Mark
