Upgrade NowAny particular brand you like?I have a spool of kevlar thread that is just so over twisty like that. Horrible stuff.
Don't give up. I've found several other spools, different weights, less Twisties.
(red face) I looked, none of my spools are marked, not manufacturer, nor where or when I bought them. Hmmm...Any particular brand you like?
Using ‘chute swivels. It happens on descent. Then gets worse on transport home, especially if I have to bug out in a hurry.Dude that happens with elastic too....Did it happen during transport or at the launch? I won't lie once in a while I untangle them, but its not bad. Are you using chute swivels too?
I buy Emma Kites stuff from Amazon. Kevlar and Elastic.
Ok! I will try the 250 pound stuff as shock cord. I thought the 250 pound kevlar was overkill for low power rockets, but as long as it is light and not bulky, it matters not. I will do overkill for no tangles.Try heavier Kevlar. I stopped using anything under #250 as it tangles like crazy. Only use I have for the thin 100# stuff is to make shroud lines for my chutes.
I take mine and out them all in plastic bags them a tote. That way they don't get tangled. Best thing is right after flight. Wrao them up like your flying again but not, and then transport them home. Or like said use a bigger size like 250, it won't hurt. I mean do whats best for you, tossing mine in bags or wrapping them with bags and then elastic on the top so they stay together has been working well. And then after i get them home I take all the chutes out. Also prep the night before as much as possible but efficient and safe for transport. You can see in the picture some of the rockets have wal mart bags on them. I think...lol....this phone.Using ‘chute swivels. It happens on descent.

Dang! The big spool of the 100 pound stuff will be shelved. Maybe I will get into kite flying?Ok! I will try the 250 pound stuff as shock cord.

Yeah I use braided kevlar I should have mentioned that.Two words: braided kevlar.
If it's much thicker and heavier than needed....who cares? Unless you're doing an altitude attempt.
I have a spool of twisted kevlar, 200 lb, over 200 feet. Free to anyone willing to pay postage. Ain't never using twisted kevlar again.
You could use the 100 pound for spare shroud lines or like Alpha III sized rockets.Dang! The big spool of the 100 pound stuff will be shelved. Maybe I will get into kite flying?

I am going to order a spool of the 250 pound or 300 pound braided kevlar and see if it tangles less. I launch mostly BT-50, BT-55, BT-56, and BT-60 sized rockets. The tangled kevlar cord was in a BT-60 sized rocket. I figure the 300 pound kevlar, even though it is over a millimeter in diameter, ought to fit in there fairly easily.Yeah I use braided kevlar I should have mentioned that.
No one's mentioned it because most LPR rockets don't have the space or payload capacity to carry shock cord that's 1 inch in diameter.I'm surprised no one on this thread mentioned the use of tubular nylon. I have several 1" tubular nylon shock cords / harnesses. Any twisting that occurs during descent is easily corrected. They work fine every time. Vendors typically sell 1" tubular nylon shock cord for about $1.25/yard.
Awesome. I use a mix of all, from 150, 250, 550, to 1800. Mostly from Amazon and Emma kites, they sell good elastic too. If I use that I make sure it can be easily replaced like below. And the rocket shops use Emma kites, your saving money by going right to the source. Im really picky about storage and transport, my one High-Flier XL has a shock cord about 10 feet long that gets tangled a lot, lol. I added a pc of kelvar strap in the middle to stop that.

+2Two words: braided kevlar.
Hmm. Is this braided or twisted?
Maybe I will try using my spool of braided 100 pound kevlar (labeled as braided) before I buy the 250 pound stuff for $15.
Of course, $15 is the cost of an up-sized meal from McDonald’s these days. Sigh.
