try the LHS
Diablokid,
I've used one I picked up at Hobby Hangar in Chantilly in a Goldberg Ultimate Bipe, and it seems to work very well. Came with the cable, the clevises, crimps, etc. I'm pretty sure it's a Sullivan 4-40 size, but I could be wrong. They have several different types available.
Where do you fly?
