I tie the kevlar to 2/56 eyelets, then seal the knot with a drop of thin CA. I put a small piece of heat shrink over the loose end, then trim the loose end to the length of the heat shrink.

I use crimps. Never a problem. There are some threaded parts with a hole up the middle available. You push the Kevlar through the hole and tie a tight knot. The Kevlar will not pull out. Sold by Don's Hobby shop I think. the knot must be small for the clevis to fit over.

I use a 1 inch long piece of 1/16 heat shrink. Loop the kevlar thru and eyelet and back thru the heatshrink. Shrink, then add a drop of thin CA and let it wick into the kevlar and the heatshrink. Strong, lightweight, and no sharp edges.

Sullivan makes a neat little 2-56 clevis rod end that has a hole just the right size drilled up through the shank. You pass the kevlar through the hole, double knot the end, secure the knot with a of thin CA (this is important - kevlar is notorious for knots not holding :-) ). Pull it snug then screw on the clevis and ur done. Once you get everything hooked up and proper tension set, a smidge of CA on the clevis thread will lock it in place. Works swell.

I had a piece of Kevlar that failed on the first flight, the edge it failed on wasn't sharp. A friend had his nylon coverd kevlar do the same. For both it was on rudder and didn't cause a crash. A setup similar to the sullivan clevis. No more kevlar for me, I stricktly use nylon covered steel available from Bass Pro cheap. If you stay with kevlar use the sullivan 2-56 eyelets, smooth surface. I use a piece of small aluminum tubing crimped, plus a drop of ca. Also use heat shrink over the tubing.

I use certified aircraft 8 point crimpers to crimp my ends on. You will never lose one of them crimped with that style. The plain jane crimpers can occasionally let go however, and CA helps a bit that way.
