Re: Spin
I don't think the objective is to make your bottle rocket to spin. Nevertheless, if you put your fins on at an angle, the rocket might just spin.MaeleeB wrote:How do you get your rocket to spin? We have tried making a gap between the fins and the bottle, but we still aren't getting good rotation.

Re: Spin
Why do you want your rocket to spin? I saw competitors with rockets that spun and didn't get a good score.MaeleeB wrote:How do you get your rocket to spin? We have tried making a gap between the fins and the bottle, but we still aren't getting good rotation.

Re: Spin
We are new at this so obviously our understanding was wrong. At the invitationals we have been to the rockets that came down spinning were in the air longer, so we were thinking (perhaps mistakenly) that to increase our time we need spin. That is not the case?

Re: Spin
Not to my understanding, it think that the rocket that fly with no spin are the best.MaeleeB wrote:We are new at this so obviously our understanding was wrong.

Re: Spin
It depends on the rocket, but what I've observed at competitions is that rockets with spin tend to have a sLiGhtly faster (albeit very pretty) descent. try to focus more on descending drag, I guess.
