And this is what I did...keep in mind I am an idiot, and my advise is suspect!

I used DuBro 618 4-40 Rigging Couplers to attach the cable, and DuBro 2139 Ball Links to attach the cables to the servo horns. I didn't want to just loop the cable thru the servo horn..looked like it would saw thru the plastic servo arm...so I isolated the cable via the 618s/2139s. This gave me adjustment on the servo end as well.

This is the end that I didn't see in the instructions, but being an idiot I forged ahead as best I could. Probably overkill, but they are still as tight as the day I hooked them up. I like ball links, and hey! It's only...money!

If you REALLY want me to drag my plane over this scanner, I'll give you a pic. Shoot, I might as well start clearing stuff off now!
