How do you terminate the kevlar? Most specifically, how do you "tie" it
Do you use brass crimp sleeves like with metal cables? Seems like tha
mught cut the kevlar..
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
remove my-wife to reply :-)
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
sharp. A friend had his nylon coverd kevlar do the same. For both it was on
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
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.
