Kevlar, definitely a better choice. I personally no longer use elastic or rubber band materials in my rockets, they all get long kevlar or nylon shock cords.Ok thanks. I went ahead and mounted kevlar 3x length of bt. On top of that double the kits shock cord. Elastic is ok?
Only you can answer that question, but it does need to be at least three times the length of the the longest your canopy can be.I can cut it shorter if necessary. I just saw it mentioned in an Apogee video to use 3x length of bt. Should i shorten it?
