I'm building an egg lofter for an altitude competition, this is my first time. I'm trying out OpenRocket to model the rocket but it's been bothering me whether or not it matters how long my rocket is. What exactly does the length of the rocket affect? Whenever I shorten the rocket, OpenRocket just keeps telling me the apogee will be higher and higher. How short is too short? How long would be good?
Also, i'm not sure how large the inner diameter of my body tube should be. I want to easily fit an 18" parachute, but at the smallest possible diameter so the rocket is skinny as possible. My current diameter is 2.7cm, which I just picked arbritrarily. We're only allowed a B6-4 motor, which has an 18mm diameter
Last question how do i delete a thread?
