Joe,

I've always had good luck with pulleys. You can get them from Hangar 9. They stay tight throughout the whole range of motion, and I've set them up crossed as well as straight. If the exits on the side of the fuselage aren't 45mm (which is the width of the pulley), then I usually cross them. If they are close, I prefer to keep them straight. The attach point of the clevis/MK end/ball link, is always in the center of the hinge line in my setup. I try and keep the same width at the attach points on the control horn as I have on the pulley, however if you're a little wide, it won't hurt anything. Try and get it as close as you can though.

My pull-pulls have always been guitar string tight, and I've not broken one ever. Get a pulley, threaded couplers, and your choice of connector from your LHS, and go to Gander mountain and get some 60lb test braided steel fishing leader and you're in business.

Easy to install, easy to setup, and easy to maintain. For lazy people like myself, it's heaven.

If you need any pictures, I can take some for you.
