I've planned my medium/high power rocket design for a level1 attempt, early next year. I've just bought some 750lb Kevlar cord and am looking at swivels for the parachute. Up till now on low power rockets I've used swivels that are usually used by anglers, with no problems.
I was wondering what load I really need to account for. At level 1, is 750lb a bit over the top? Are angling swivels actually strong enough?
On OR I usually go for a delay that gives me an ejection velocity of between 5 to 20 mph. Is this reasonable? I don't like using parachutes that are too big because I'm not a fan of long countryside walks to recover the rocket.
Yes, I could calculate the loads but would rather rely on the experience of you all than my jaded and revised mathematics.
SO.
