Hoping to two two launches of the Mega Vector Force this weekend - the first, smaller one on the smallest AT 38mm motor I could find, mostly as a shakedown; the second with a big honkin' I280DM - that should get me within about 500 feet of the mile mark.
On that note... OpenRocket says optimum delay on that flight is 13s. The I280DM comes with a built-in delay of 14s. I'm using a Chute Release, so I'm not yanking out a massive chute. Worth drilling the delay, or just let it do its thing and maybe it pops a second or so after apogee?
Also: I've used my Chute Release on big-ish flights and big-ish rockets before (2300' AGL on my L1 in an Estes Argent), but this is a lot bigger: >4000 feet on a rocket that's about 1kg dry. I figure it'll hit terminal velocity pretty quickly, but should I be worried about the "yank" of the CR opening? Suggestions for an opening height? I usually do 200' on F and small G, 400' on G and H. I'm thinking 600 feet just to make sure everything comes out.
Looking forward to this one....I've been working on this rocket all winter!
