Default Kevlar Cord

Hey guys would this Kevlar cord from Emma kites work as shock cord mounts?

Absolutely! I use it in every build. I tie a loop at just shy of the front end of the BT, then attach the elastic shock cord to the Kevlar loop using a loop I made in the elastic. Having them attach that way helps to minimize any zippering and is easier on the body tube end. The Kevlar will slice through the BT otherwise.

Hope this helps!

I do love their pricing for this Kevlar cord and the various sizes available. Just don't be in a big hurry, as my orders came across the ocean!

The Emma Kites braided kevlar cord is good. I like the 500-lb. cord for model rockets. It's narrower and more pliable than 1/8" elastic, so it packs into the airframe easily.

It's what I use also. 100 lb. for 18mm engines, 500 lb for 24mm and larger engines. I anchor it to the engine mount assembly.

Default So use both elastic AND kevlar?

I'm considering buying some Kevlar cord - but I should use elastic too?

Is there any way you could post a pic to show this?

I guess it depends on who you ask. If your Kevlar cord is very long than you might not need elastic also. Personally, I only use the Kevlar as a leader and tie the elastic to it just inside the open end of the body tube so the Kevlar doesnít slice through the body tube at ejection.

Use both just as jeffyjeep above describes for up through "G" power.
Anything HPR just use Kevlar, in a LONG length.
