OK, I will bite, what's a Sullivan wire?
Now I will have to look that up.
I saw what I think you are talking about at the local hobby shop the other day with a Sullivan label on it. It was a plastic sheath with wire rope to run through it with some solder connectors included.
Is that what you are talking about?
What I saw, and maybe they come in different sizes, looked like it was really overkill for throttle linkage for an 82.


On edit, I looked up Sullivan RC Products as I had seen their website once before. It appears there are many types of control other than what I saw the other day.
It appears that I may have to make an order over the internet however as my little local shop does not carry anything like I like on the website.
Maybe that's why the local guy at the club suggested piano wire in a sheath as we can come up with that stuff locally.
When you live in a small town you have to get creative sometimes to save shipping.
