Hi everyone,
I'm in the final stages of a scratch built level 1 rocket. It is 5.5" diameter and 50" long. I expect it will weigh somewhere around 8lbs when it is launch ready. My question for the group is around the shock cord. I have 5/8" diameter nylon cord and I was planning on 3x the airframe length (or 15'), although I guess I could go longer. For high power, do I need anything to absorb some of the energy from the charge? I don't think elastic would be strong enough, but perhaps surgical tubing would. Would a deployment bag help in this area? I really appreciate your input.
