A friend of mine is working on his first rocket, an Alpha III, and was wondering what he should do about the shock cord. I use elastic nylon and go by the "twice as long as the rocket" rule, but all of my craft are at least 1.34" in diameter and generally longer than a foot. Would this be effective for a short rocket with a narrow diameter, or would you risk running out of room for a parachute and wadding? I imagine it would also be a nightmare to pack.
