I have not seen this done before but that does not mean it has been which is why I am seeking your advice. I want to power my elevator with a single high power digital servo. I am thinking of using two graphite control rods back to the split elevator halves but connected at the same link on the aluminum servo wheel. Something like 4-40 HD ball links stacked one on top of each other with the 4-40 bolt going through the two connectors tapped into the aluminum rod. The tubes will be the same length.

What do you think?
